Newton's Laws of Motion Overview

Hello everyone! Hello Tutor Z! Hello good afternoon Tutor Marky! Hello good afternoon po! So kamusta ka po Tutor Z? Well maraming trabaho pa rin Monday na Monday is Tutor Marky kaya tambak ang trabaho natin ngayon. So ako naman Tutor Z makuwento ko lang po, ako po ay fully vaccinated na! Wow! Sana all! Hello po and good afternoon sa ating mga grade 8 learners at saka grade 8 teachers po na nandito. Siyempre po, Tutor Izzy, kamusahin po natin sila? Yes po, meron po tayo, Tutor Marky, si Joseph Conrad Bulaclac. Hello po sa lahat, Joshua Passion. Good afternoon, Joshua Passion, grade 8 Einstein, watching from Laulo, National High School, SDO, Cagayan Region 2. Nandito rin po si Jemz Ngalo. Good noon po, watching from North Cotabato Division. And Sinadin Domingo Manabat, good afternoon, Sinadin Manabat is watching from Ingud Ramona Integrated School, Angadanan West District, Grade 8. And the rest, Tutor Marquis? Yes, po. Hello, good afternoon, kay Zanzia Faye Maludon from CNHS, kay Nora Padilla-Burce, kay Rubin Gabriel Dolamor, kay Marla Alcontin-Muñoz, kay Athena Sainel Salvador from CUPIS National High School, and of course, kay Joey... Good afternoon everyone. Yes, good afternoon. Of course, let's go with Joshua Passion. Hello! Again, we mentioned the two of us. Tutor Markie, what are we going to study today? To those who are watching, I am now Tutor Markie's student. Hello, Ayo. Hello, of course, I'm Tutor Markie from SDO Bulacan. And of course, I'm with Tutor Z from SDO Tarlac Province. And of course, Tutor Z mentioned earlier, so what are the things that we will be remembering this afternoon? So, since we are now on our week 3, Tutor Z, and our topic for this afternoon is the loss of motion. Wow! Yes, Tutor Izzy. So, I'll just tell you, Tutor Izzy. Maybe this is my favorite topic when it comes to physics when I was in high school. So, of course, yes, this is the resource we use. There, to Ma'am Lani, good afternoon. Okay, this is the writer of Ma'am Renan, Bacolod, and Elma Cordova. Yes. Alright. Of course, in every topic, Tutor Z, like in the past two weeks that we have had a session, of course, we have the most essential learning competency. What is that, Tutor Z? Well, for our week three, Tutor Markin, everyone, our most essential learning competency or our target to learn is to infer that when a body exerts a force on another, An equal amount of force is exerted back on it. Kumbaga, makikita natin na kapag may pwersa daw na inapply, naturally, yung naalala mo Tutor Markie last time, may natural force, naturally, may kokontra dito. Katulad ng pagbinanga mo, natural, lalaban yung binanga, Tutor Markie. Yes, tama ka, Tutor Izzy. And of course, syempre, ito yung kasunod or magkakonekta yung topic natin, Tutor Izzy, nung nakaraan. and also this week 3. So, it's time now. But before everything, of course, shout out to Jasmine Bautista from Santa Lucia National High School, to Luis Errol Faustino, to Anzir Keen Sakdalan, to Karen Adelan, to Emmanuel Citaroza, and to Freak C. Zile Agno. Hello, good afternoon, happy work. Enjoy having our lesson for this afternoon. Okay po. So for the week one, of course, we have three objectives, Tutor Z. First is to differentiate law of inertia, law of acceleration, and law of interaction. So what is the second one, Tutor Z? The second one, Tutor Marquee and everyone, is to explain how mass, remember, mass is what's inside the body, not weight, explain how mass affects the object's inertia and acceleration. Tutor Marquee? And of course, our last objective is to know the different loss of motion. What are the situations for our daily living that we can apply those losses? yes situation and to start our our session for this afternoon so grade eight prepare your papers and notes. Of course, our viewers can also comment so that you can answer your questions and we can see if you can answer the questions that we presented by Tutor Z. For the free test, this is just 5, Tutor Z. So multiple choice lang naman siya. So read the questions carefully. Write the letter of the correct answer on your answer sheet. Or yung sumang nanonood dating live dyan, so comment dun sa comment box. Okay. For number one, Tutor Z. Basahin ko, Tutor Marky. Yes, po. Okay, so para sa ating number one, mamaya nakikita ko ang dami na naman nagko-comment. Babasahin natin lahat yan. Sana walang malampasan. Number one class. Who formulated the three laws of motion? A. Alexander Graham Belba B. Aristotle C. Isaac Newton or D. Thomas Edison This is easy. We're idols. Let's see. Actually, Tutor Izzy, we already mentioned the answer in our previous session. There's someone who answered. Joshua Passion. His answer is letter C. And also Fortune Flower. Ang ganda ng pangalan. Letter C. And si Emmanuel Tarroza, Isaac Newton, tutor marquee. Okay, so let's see ano yung correct answer. All right, very good. Yes, also letter C. Si Janela Acob, Domingo rin tutor marquee. Andrew Sembrano, Anze Keen, Garcia Saldalan, Athena, Chanel Salvador, and everyone else. Babalikan natin. Okay. Okay, for the question number two, sigura ako naman ako to tutor Z. So which has the greatest inertia? Okay, is it letter A, airplane? Letter B, bike? Letter C, car? Or letter D, jeepney? So grade 8 learners, comment your answer. Hello po kay mamilinda Espino Mano. Okay, watching from Santo Lucia National High School. Hello po. So grade 8, what is your answer? Sabi ni Joshua Pachon, it's letter A. How about the others? Again, si Patrick J. Valderrama, ang sagot din niya letter A. Si Fortune Flower, letter A din. Okay, so mostly ang sagot nila is letter A. So what is the correct answer? Alright, very good, letter A. It's the letter A. Okay, for the third one, Tutor Z. Yes. So para sa ating pangatlong katanungan class, number three. All of the following apply the third law of motion except... A. Kicking a ball, B. Rowing a banka, C. Taking out ketchup from a bottle, or D. Throwing a stone. Alright, so what are their answers? Ivan said A. Joshua Pasion said A. So let's reveal the answer. The answer is letter A. Thank you very much. Very good. Patrick Vivalderrama, sir. Anzey Keen, Nick Lumibao-Veloso, Janela A. Acob, Domingo, Frizzis Al Agno, Josephine May Sereno, Angel Jamaica Antonio, and Andre Dupan. Letter A, silanglahan. Very good, guys. Very good. Very good. For next question, question number four. Which Newton's law explains when a man is pushed forward in the car as it stops? So is it letter A, the first law? Letter B, the second law? Letter C, the third law? Or letter D, the second and the third law? Okay. Come on. Come on. Grade 8. So what is your answer here in question number 4? Okay. It says Joshua Pachon. It's letter A. Emmanuel Tarroza, letter A. Okay. Sineka Veloso, letter A. Santia Femaludon. Okay, Josie P. May Sereno. So, mostly, Tutor Z, ang sagot nila is letter A. So, tingnan natin kung tamaan sila. Okay, very good. It's letter A. Very good, guys. Very good. Okay, very good. Brian Jake Saliva. Ayan. Okay, Tutor Z. All right, for the number five question class, two balls are simultaneously applied with a force. So, dalawang bola of... 20 newton. Naalala niya yung letter N newton, diba? Basta fuerza newton. Dalawang bola, 20 newton ang inapply natin. One ball has a mass or yung katawan niya siksik ng 0.3 kilogram. Yung kabila naman ay 0.4 kilogram. So medyo masiksik yung isa, yung 0.4. Which ball has a greater acceleration kung parehas na 20 newton ang binigay nating pwersa sa kanila? So the options are, Tutor Marky? Okay, letter A. They will both accelerate at the same rate. B, none of them will accelerate greater than the other. C, the one with a mass of 0.3 kilogram has the greater acceleration. Or D, the one with a mass of 0.4 kilogram has the greater acceleration. So, Tutor Marky, we have here Ryan Jake. So, Liva, five letters C, Tutor Marky. So, let's see what the correct answer is. So, let's reveal now the answer. All right, letter. C. Letter C. Masyado mabilis yun. Daming ating participants. Kaya nga po, Tutor C. So kung makapasin niyo po, Tutor C, sa question number 5 po natin, may mga numbers na involved. So hindi po bang sabihin yan, Tutor C, sa topic natin ngayon, ay may mga numbers din na tayong may encounter? Of course. Sabi ko nga last time nung nagsimula tayo, Tutor Mark, di siya school year, di ba? Ang math actually is part ng science. That's why our scientists have numbers. And in the Philippines, we're looking for Newton. And acceleration and the others. Yes, yes, yes. So let's move on. Thank you very much, Reynid, for your participation in our pre-test. So let's move on. So just a review. So if we're going to... So we can see here that we have four pictures with our Z. So the letter A has a magnet. Okay, letter B, may airplane na lumilipad. Letter C, hinihila nung tao yung aso niya. And letter D, nagbabite. Ito talagang nangakunin ako dito kasi nagbabite ako tutor ngayon. So ngayon, ang question ko sa grade 8 learners natin, ano sa tingin nyo yung pagkakapare-pareha nung apat na to? Yes. So while we are waiting, tutor Marky, shout out kay Jester. Velasquez watching from Santa Lucia National High School. Also, kay Christine Tubig watching from Santa Lucia rin. Christian Timothy Dale Cabrera from Santa Lucia rin. Lahat sila nanandun. Pati si Velasquez, Jester, lahat sila nanonood sa atin. Alright. May nagsagot dito, Jester Velasquez. Sabi nga, 1, 2, 3, Law of Motion. Okay. What else? Okay. Lahat ba to ay gumagalaw, Tutor Izzy? Kumatingin mo? Yes, of course, obviously. Pagdating sa picture class, makikita naman natin yung visual clue, diba? Siyempre, pag may nagsasaguan, yung katulad nagsasaguan, Tutor Marky, may tumatalsik, and mapapansin mo yung aso, halos hindi na makatayo yung humihila sa kanya. Yung airplane naman, natural na lumilipad dyan kasi wala tayo nakikita ang ground. Kung di lumilipad dyan, babagsak. And of course, dahil nakaupo at nakataas yung dalawang paano nagbabike, natural na umaander yan. Alright, thank you po, Tutor Z. So, ang sabi dito ni Joshua Passion, there is motion. So, correct. So, lahat sila ay gumagalaw. And of course, kapag gumagalaw ang isang bagay, there is a certain force na present. Tama ba, Tutor Z? That is correct. Yun din po ang sabi, Tutor Marquee, ni Emmanuel Citaroza at saka ni Fizi Zahil Agno. Ayan, ang gagaling naman na ating mga Grade 8 learners. And hello po din sa mga teachers po nila na nag-sabi o nagbanggit ng, Oy, manod kayo ng tutorial session ng Grade 8. Alos lahat yata, Tutor Margin, yung Santa Lucia National High School nandito. Hello po sa aking mga Tagalusians there. Maraming salamat po, supporta. So, Grade 8 teachers po kay Sir Pong at sa kay Ma'am Grace Parungaw, hello po. Thank you very much po. And of course, yaman din lamang nabanggit po natin yung... force ito po yung mga tao behind the concept of force so ayan po apat po sila na pinepresent natin dito so tutor z ang unang unang po dito ay si aristotel yes so si ang konting hapyaw lang naman po tutor z kasi po dun sa kung baga itong introductory concept po Arisotel, grade 8 learners, said that... If an object is continuous, it needs to be applied force. And when it applies force, it will be faster. That's what Aristotle said. The second person is John Theloponous. He first introduced the theory of impetus. So, here it says, if the impetus is lost or or decreases, the speed of an object will also decrease. Or it means, the movement of an object will slowly decrease until it stops. Yes, Tutor Markie, I'll just insert it. For those who... Remember earlier, Tutor Markie returned? Okay. Actually, Aristotle also applied the idea of impetus. Let's go back to the next slide. Ang impetus class, ang ibig sabihin nun ay yung pwersang existing. Ibig sabihin, kapag hindi siya gumagalaw, yung impetus force niya ay resting. Tapos kapag gumagalaw naman siya, yung impetus niya habang gumagalaw is yung moving na force. Yun yung ibig sabihin ng impetus. Yes po. So for the third person, okay, NMC Jean Buridan. So, dito may tinawag siyang mover or tagagalaw. Okay? So, ang sabi po niya dito, motion is possible through a mover that keeps the object moving with power proportional to the speed and mass of an object. So, in this particular idea po ni Buridan, meron na pong bigat or may mass na po siyang involved as well as speed. So, that's what Tutor Z mentioned, Grade 8, the impetus. Here, the term force is mentioned first as the impetus. So, our next is Galileo Galilei. So, he claimed that even without a continuous application of force, an object can continue to move with constant speed in a straight line provided there are no outside force acting on it. So, Tutor Z. Galileo Galilei contradicts the idea of Aristotle. Am I right, Tutor Z? Yes, that's correct. Okay. And of course, the idea regarding that particular force or movement of a certain object has solidified because of Galileo Galilei. Pero may isang tao, Tutor Z, na ginamit. yung idea ni Galileo para po magkaroon po tayong ngayon na tinatawag na three laws of motion. And siya yun po siya, siya po ay si Sir Isaac Newton. Yes, that's correct. Sir, the laws of motion. O nga, Tutor Markie, banggitin ko lang dito, isa sa paborito kong laws of motion ni Isaac Newton. Kunwari, hindi tayo magagaling na sa science. Pero meron tayong matatandaan, yung an object at rest remains at rest, and an object in motion remains in motion unless merong pwersang magbabago nito. Okay. And that is what we call the first law of motion. Kaya yun na natandaan ko eh. Okay. So, grade 8 learners, nabanggit nga po ni Tutor Z, so an object at rest remains at rest. So, like for example, Tutor Z, itong nasa... Let's go to the next slide. There is a ball. What is this ball? It's a soccer ball. Soccer or a football. If you can see, it's at rest. That's right, Tutor Izzy. Now, there. There's a ball that a child will hit. When the ball is hit by a child, what will happen is it will move. So, when it moves, keeping the goal, the net shooter Z stops the ball. So, from that, this is an application of the first law of motion, which is the law of inertia. There. Shooter Z, what is the law of inertia? Yes, class, the law of inertia, it is the Newton's first law of motion, yung tinatawag na na law of inertia. Ang sabi ng law of inertia ni Newton, an object at rest remains at rest and an object in motion will continue to move at constant velocity unless acted upon by a net. Force. So, ibig sabihin nito, class, katulad nga nang sabi natin kanina yung impetus sa tutor Marquee, kapag ang object ay atres, meron ng force yun, pero atres ang kanyang resulta. Tapos, yung motion naman, yung gagalaw. So, basically, magbabago yan kapag merong outside force na makikisali. Tulad ng bola, atres yan, yan na yung force niya, atres, pero may outside force na tumira sa kanya. he moved it. And while he was moving, there was an outside force that stopped him from moving. So basically, there are two forces, the one inside and the one outside that will be involved. There. Thank you, Tutor Z. So hello to our viewers, to Joshua Passion, there, Law of Inertia, to Manuel Tarroza, Law of Inertia. Yes, and I would like to read this too, Tutor Marky. This is my idea always, why I love science class. Jester Velasquez said, science is everywhere. That is correct. All of those, including the Filipino-English subjects, were based on the ideas of science. There. So, next slide. Okay. So, for our next slide. So, there. Tutor Z, there. So, there's a man who's in a car. Maybe Tutor Z runs fast. So she ran to the wall. The tendency of Tutor Z is that she ran away when she ran to the wall. Yes. So what do you think of Tutor Z or Grade 8? What do you think of the man not wearing clothes? Why did she run away? Let's see if our Grade 8 learners know. So why did the man run away? What did he not do while he was in the school? So while we are waiting, Tutor Markie, we have people from other schools. Nika Dikinya from Canaan East National High School. We also have Danica Gamula. Good afternoon, sir. I'm Danica Gamula watching from... Rangayan City of Ilagan Isabella, teacher subject, Ma'am Karen Adelan. Hello. Hello, hello. Ayan, dami lang sumo ko Tutor Izzy. Sabi nila, sabi ni Joshua, hindi po siya nagsuot ng seatbelt. Ayan, sabi ni Joanna, seatbelt po. Sabi ni Judy, seatbelt. And Anze, Dakeen, Garcia, Sakdalan, Frixie, Agno. Ayan, so correct. So kasi. He didn't wear a seatbelt. Seatbelt grade 8 is very important because since we are applying the law of inertia, while the car is constantly moving, if there is no outside force, no one will stop him. In our example, the wall stops him. So, the tendency of the person inside the car, okay, he said this, he will run and run. So, the one who will make the man safe or make him live is the seatbelt. Right, Tutor Z? Yes, that's correct, Tutor Marky. Okay, next. So, will this vault stop? Okay, so patuloy na umiikot. So, may nabanggit na ako kanina dito, sabi ni... Who is that? It's Jester Velasquez. Sir, it is because of the presence of inertia. So, here, it is the tendency of an object to maintain. So, it's inertia, as Tutor Z said earlier, while it's resting, still there is an inertia because it has force applied. If it continues to move, still there is an inertia. So, and also there is a velocity. So, this is what we call... inertia. Of course, it may be happening in a straight line. Tutor Z, what is observed by our students? Maybe, sir, who wins the strength. Because the other one, although she has more inertia, because her mass is greater. The other one is moving, however, the bigger one is smaller. So the bigger one will win. Although we said that the inertia diva class is... Pansinin nyo yung isa gumagalaw, yung isa hindi. Tandaan na yung pinag-uusapan natin dito is yung first law of motion na an object at rest remains at rest. Yun yung parang malaking elepante. May force pa rin kahit hindi siya gumagalaw. And then an object in motion remains in motion. So parehas silang may inertia. Magkaiba lang yung state nila. And for that, thank you very much Tutor Izzy. Mas pala Tutor Izzy, nabanggit mo kanina yung bigat. So it may affect also the inertia, is that right? Yes, mass, tutor, multi-mass. So the greater the mass of an object, the harder it is to move when it's at rest or difficult to stop when in motion. So there, so Joshua Passion is right, that's what he said. So here, tutor Izzy, there are two balls, one is 300 kilograms, the other is 30 kilograms. Yes. Tutor Izzy, kung na-gets ng mga grade 8 natin yung previous topic natin kanina sa previous slide. So, sige nga, grade 8. So, yung first statement natin, objects with a greater mass have blank inertia. Is it more or less? More or less, class. More or less. And while we are waiting, Shira Jel Ampan Tamaing watching from... Hello to Ferdinand Alexis Glorioso from Doña Candlara Meneses Duque National High School. Hello. And Audrey Mara Luta watching from Raniag High School, Ramon Isabela. Okay, there's an answer. Tutor Marky. Jester said it's less, Andre said less, Francine said less, Sancia said less, Manuel said less, and Catly said less. Okay, so the correct answer is more. More. Okay, it's more. Okay, the greater the mass, the greater the inertia. So, it's directly proportional. So, if one thing is heavy, the other thing is also heavy. So, next po. Okay, Tutor Easy. Alright, it takes, okay, class, more or less ulit ang question. It takes blank force to change their motion. Madali lang to. Come on, wag nyo isipin mahirap ang science. It takes blank force to change their motion. Is it more force or less force? Ayan. Okay, may mga sumasagot, Tutor Marky. Si Fortune Flowers, sabi niya, more. Judy Ann Enriquez, more. Ganun din si Kurt and Andre Dupan. Sabi ni Immanuel Tarroza, more den. Si Jester, less. Si Jasmine, ano yun, Dago, less den. Okay, so let's see. Tutor Izzy, okay, the correct answer is more. Okay, thank you very much. Galing naman. Next. Okay, so after the first law of motion, which is the law of inertia, let's move on to the second law of motion. Okay, second law na tayo. Okay, second law na tayo. So, ngayon, ayan. So, kung makikita po natin, may, may, may, anong tawag dito? Pinupukol yung lalaki. Yes. Okay, so therefore, my force. So, so from that, Tutor Z, okay, it may explain with this particular picture. So if we're going to explain this, yung nasa taas po, may ina pa siyang 20 newton sa 5 kilogram na mass. And then therefore, meron po siya tutor Z na mataas or mabilis yung kanyang acceleration. Dito naman po sa ilalim, although parehas po sila tutor Z, grade 8 ng... ng mass which is 5 kilogram ang inapply po tutor Z nitong pangalawa is 10 newton lang 10 newton lang of course ngayon po low lang ang acceleration nya tutor Z so from that it may explain the second law of motion which is the law of acceleration yes tutor Z the law of acceleration class is the second law of motion na nag-estate na the acceleration of an object is directly proportional or uh to matapat okay the um ratio to the net force acting on it and is inversely proportional to the object's mass. The direction of the acceleration is in the direction of the net force acting on the object. So, Tutor Marquis? Okay po. So, dito sa law of acceleration, Tutor Z, may dalawang quantity na tayong present. So, dito, taplo pala actually, si net force, si acceleration, atsaka si mass. So, grade 8, naroon silang relasyon sa isa't isa. So, sabi nga dito sa... In our first sentence, acceleration is directly proportional to the force. So, it means, the higher the acceleration, the higher the force. Like in the first sentence. So, the second sentence, it's okay. Acceleration is inversely proportional to the mass. So, it means, when acceleration is low, the mass is higher. So, inversely proportional. sa liwa. So, regarding tutors in the direction of the acceleration, kung saan papunta yung acceleration, dun din papunta po yung net force. Yes. I-clarify lang natin, Tutor Marky, para lagi nila naalala. Yung mas na sinasabi ni Tutor Marky is kung gaano kasiksik yung object, okay? So, katulad na nasa picture, Tutor Marky, sabi mo nga, magkaibang pwersa ang binigay, pero same object, parehas na quantity of matter inside that object. One is faster because the force is stronger. The force is too much. Then, same object but the force is weak. So, there's only a little acceleration. There. So, happy viewing again to Bea Sandra Ronas. Hello there. And to Tutor Z, we didn't mention you earlier. So, next week. Okay, next week. In week 4, we will award Tutor Z the most active here in our Tutor. Most active. And then, who is the school that always participates with us. And also, the SD. Right, Tutor Z? That's right. Too bad last time, no one answered the special question. Too bad. How much is that, Tutor Z? 100 pesos load, I hope. I thought it was a sauce. So moving on. Hello. Hello to Kenneth Vivar Calara. And of course, Tutor Z, because we already have numbers that we are discussing here. Of course, I know Tutor Z, as a review, Tutor Z also mentioned this in Week 1. Regarding the units involved in computation of the acceleration, we have three systems, the MKS. the cgs and the fbs but to thursday in the philippines what we use mostly here is the mks we have here the combination of mass and acceleration to make it force and that is the newton okay so when we will complete the problems regarding acceleration we're going to use the uh this unit the kilogram for the mass meters per second It's for the acceleration. And for the force, it is the Newton. That is because we are in the Philippines. Tutor Markie is in the class. That is the international system. And you know in the Philippines, if it's international, that's what we will follow. So it's the same. Okay. So hello to I-Din D. Iglesias Julio from Ranyag High School. You have eight competencies, right? na competent. Ayan. I love physics, sabi ni Jester Velasquez. Ayan. Okay. Next, so ito po yung tutor Z, yung formula na ginagamit natin for the law of acceleration. The F is equal to MA. We're in F, that means force, M for the mass, and A for, small letter A for the acceleration. So force, kapag ang unit natin for force is the Newton. Newton. So, Tutor Z, for us to get the formula, we are going to apply this particular formula. So, I am teaching you this face-to-face, the triangular method, FMA. So, how do we use this in grade 8? So, if it disappears, like for example, letter F, that means force. If the force disappears, let's cover it. then M and A will be left. So what we will do here is we will multiply M by A or we will multiply mass by acceleration. However, if... If A or acceleration is missing, we will divide force by mass. And for the last one, what happens if letter M or unknown C, M or C mass is missing? We will divide force by acceleration. Yes. So, Tutor Markie, let's repeat it. If force is missing, M or A division is missing. Yes, sir. If force is missing, MA is there, multiplication. So, it's just two things. Yes, that's right. And for that, we will apply this TutorZ through the problem set. So, now, to our Grade 8 learners, prepare your mathematics ability. So, let's exercise that. There. Joshua said there's also a math pyramid method. There. no ah physics enthusiast talaga tong si joshua so good afternoon kay kian everyone so watching from pnhs and of course kay ah kay stella lapus from partida national high school san miguel bulacan so we are invading mga tango bulacan tutor z so let's start po tutor z just sa problem natin so dito daw tutor z merong track okay may track daw so ang track ay may be got or my mask now one thousand kilogram so you want to awesome kilogram night on the other national track for the track go Magalha and pop on Tasha now is acceleration is four point five thousand meters per second squared so my own question at Indy to find the net force needed to accelerate the car the truck okay so my own tutors II sempre What will we do first when we analyze the problem? What will we do first? Identify the variables, tutor marquee, or the available numbers. There, very good. Tutor Z is correct, grade 8. So, let's look for the variables. So, what are the given and what are the unknown? So, here, okay. These are the given. So, Tutor Z. Yes, our given class is our acceleration. 4.5 thousand meter per second square. Then there's the direction of the east. So if it's acceleration, remember the direction. Its mass or its body is 1,000 kilograms. So what's missing is the net force. Net force. Thank you, Tutor Izzy. So there. Grade 8, you can see here the symbol of A or acceleration. It's a small letter and it has an arrow at the top. Okay, that means it's a vector. Vector quantity. So, we need it in direction. So, that's it. Peace. So, now, of course, as Tutor Izzy said earlier, what we're looking for is net force. So, let's go back to the formula. So, what is the formula when we're looking for force through the law of acceleration? Right? This one. okay f okay f is equal to ma so if you're going to apply the triangular uh concept canina so meron tayong mass which is 1000 meron tayong acceleration which is 4.5 thousand meters per second squared ang gagawin yung dito tutorzi ay anong operation multiplication ayun kagali si tutorzi yun so now plunging the value ayun po yung So now, grade 8. So, what do you think is the answer? Okay, grade 8, what do you think is the answer to our problem? Okay, to our first problem. What is our answer here? Okay, there. So, let's see the answer now. So, we're just going to do multiplication. So, ayan. So, 4,500 kilograms per meters per second squared or 4,500 newton to the east. Ayan, ang dami nating tutors ni nakakuha ng correct answer. So, Tutor Marquee, question. Studyante mo ako eh. Ako. Kunwari, sasagot ako sa classroom, ano ang pipiliin ko dapat? At yung kilogram, meter per second squared or Newton and then direction? Tutor Z, any of the two. Any of the two because, Tutor Z, the kilogram meters per second squared and then the Newton. Same lang po yan, tutor Z. So, kumbaga, dito po sa Newton, dinisect lang natin siya. So, yun lang din po yun. Pero, syempre, huwag po natin kalilimutan grade A kasi may nakikita po ako dito sa sagot nila, wala pong direction. That is correct. Ayan. Kasi vector na siya eh. Apo. So, okay po. So... Alright, before we proceed, sir, we have some new participants. They're gone. There. Angel May Espillo from Partida National High School, San Miguel, Bulacan. Okay, so let's move to Jersey. There. Yes, sir. I'll just explain this because we have 3 minutes to go. Okay, so this guy here applied a force of 2 Newton class to the right. And the ball weighs 200 grams. So what we're asking here is what is the acceleration of the ball? So as you can see, the unit that we used here is grams. So remember when we asked you earlier about the value of Newton? So you guys, because of Newton, we're using kilograms there. So, basically, kapag ganyan yung sample natin sa problem, all we need to do is to convert that gram to kilogram. So, we have 1 kilogram is equal to 1,000 kilogram. And if we're going to convert that, it will become 0.2 kilogram. Ayan. So, ayan po. so of course identifying the the given and also the the unknown. Acceleration. Since we're looking for acceleration graded, we'll cover this. What will happen is force divided by mass. And then the correct answer is we divided this to grade 8. Force is 2 newton divided by 0.2 kilogram. And then the answer is 10 meters per second. Joshua Pasion, 10 meter per second squared to the right. Thank you, Joshua. So, okay. It's a bit long. Okay, so there's a box, class. In our third question, there's a box. Then, there's a force letter A. So, force A may apply to 20 newton. Okay, and then, in force B, there's a negative 10. Newton. Bakit negative 2, 3, Z? Kasi ito po ay Papunta sa left. Okay, papunta sa left. So, ngayon, so of course, ang given, ayan po, ang given, and hinahanap po natin yung mass. So, of course, sabi nga po ni 2, 3, Z nung previous na topic, kapag may ganyan, nahanapin po natin yung resultant force. So, we're going to apply now the mathematics from the previous lesson na ginawa natin. Ito yung the answer would be 10 newton okay and then since she's the force okay and at acceleration is 1.50 what we did here is we divided the 10 kilograms meters per second squared by 1.50 meters per second squared and then the answer would be 6.67 kilogram Good, Joshua, passion pa rin. Guru, Tutor Izzy, iskip muna po natin tong try list. So, para mo maisingal na po natin yung last. Okay, last law of motion po natin. Okay lang yung Tutor Margie kasi naintindihan naman na nila yung second law of motion. Okay po. And of course, ang kakabilib naman pati po mat-problem talagang yung problem solving na ang bilis po nilang mag-gets. Ito naman po sa third law of motion. Ayan. Kung may makikita po nyo, nagihilahan. Okay. Pero, they are in different motion a different direction rather so as well as dito kapag tayo ay tinulok po natin yung pader also tayo nag-exert ng force dun sa pader okay at yung pader nag-exert din ng force papunta sa atin tutor is ito yung balance force nung last time tama po ba okay yan so law of interaction sabi dito okay uh it states that for every action there is always an equal and opposite reaction so that's why that's what we call tutor marking normal force yes, normal force and for this it is also called law of action and reaction If someone reacts, you apply an action, someone will apply a reaction, but opposite action. Equal. Direction. And also equal. There. Okay. There. And always it should be in pairs. Okay. And there. And again, the three laws of motion, the law of inertia, the law of acceleration, and the law of interaction. So. So for the post, maybe this is just five questions, Tutor Z. Okay. So, it's just fast, grade 8. So, for the first one, it's the tendency of an object to resist any change in its initial state. If it is initial at rest, it tends to remain at rest. Is it inertia or interaction? By the way, class, while you're answering to the module, that's from what I have learned, Tutor Marquis. Tama po. Ayan. So, ayan. Sagot po ni Joshua Pasion. It is inertia. Wow. Is it correct, Tutor Marky? Let's see. Okay, very good, Joshua. And also, Emmanuel Tarroza. Hello. Jester Velasquez. Okay. Moving on for the next question. Okay, Tutor Z. Fill in the blanks with the correct terms. Newton's second law of motion is also known as the law of interaction or acceleration. It's easy for science class, right? I didn't memorize, but I remember. Is it interaction or acceleration? Jester Velasquez says acceleration. Is he right, Tutor Marky? Okay, very good, Jester. It's acceleration. Very good. Very good. For the next one. Okay, Lazaro, you did great. The law of interaction states that for every action, there is an equal and blank reaction. The last one is also a tutor mark. Yes. Is it opposite or same? Grade 8. There is an equal and blank reaction. Ayan. Sabi ni Jekster ulit. Tutor Z. Si Jekster. Binis lang ni Jekster. Sabi ni Jekster is opposite. Very good. So ayan. Sabi ni Patrick J. Valderrama. Opposite din siya. And the correct answer is opposite. Ayan. Siguro ito na yung last. Okay. Tutor Z. Alright. Direction. Identify the law of motion that applies in this picture. So meron tayong dalawang magkaibang direction na tutor marquee. Meron ba tayong option dyan? Wala po. Wala. Tatlo lang naman yan. Let's see. Anong law yan, class? Yung mayroong opposite direction, tapos mukhang same ang force, tutor marquee. Kasi yung pahanya yun eh. Law of what? Law of what? Yes. Law of acceleration. Meron dito Tutor Markey by Josephine May Sereno. Interaction, Joshua Passion. And Emmanuel Citaroza, acceleration. Ano ba ang tamang sagot? Third law of interaction, Jester Velasquez. Okay. The correct answer is law of interaction. Yes. Pang ilan to Tutor Markey? Third law of interaction. Yes, so Tama rin si Jester Velasquez. Ayan. Okay. Okay. So crazy.

Hello everyone! Hello Tutor Z! Hello good afternoon Tutor Marky!

Hello good afternoon po! So kamusta ka po Tutor Z? Well maraming trabaho pa rin Monday na Monday is Tutor Marky kaya tambak ang trabaho natin ngayon. So ako naman Tutor Z makuwento ko lang po, ako po ay fully vaccinated na!

Wow! Sana all! Hello po and good afternoon sa ating mga grade 8 learners at saka grade 8 teachers po na nandito.

Siyempre po, Tutor Izzy, kamusahin po natin sila? Yes po, meron po tayo, Tutor Marky, si Joseph Conrad Bulaclac. Hello po sa lahat, Joshua Passion.

Good afternoon, Joshua Passion, grade 8 Einstein, watching from Laulo, National High School, SDO, Cagayan Region 2. Nandito rin po si Jemz Ngalo. Good noon po, watching from North Cotabato Division. And Sinadin Domingo Manabat, good afternoon, Sinadin Manabat is watching from Ingud Ramona Integrated School, Angadanan West District, Grade 8. And the rest, Tutor Marquis?

Yes, po. Hello, good afternoon, kay Zanzia Faye Maludon from CNHS, kay Nora Padilla-Burce, kay Rubin Gabriel Dolamor, kay Marla Alcontin-Muñoz, kay Athena Sainel Salvador from CUPIS National High School, and of course, kay Joey... Good afternoon everyone.

Yes, good afternoon. Of course, let's go with Joshua Passion. Hello!

Again, we mentioned the two of us. Tutor Markie, what are we going to study today? To those who are watching, I am now Tutor Markie's student.

Hello, Ayo. Hello, of course, I'm Tutor Markie from SDO Bulacan. And of course, I'm with Tutor Z from SDO Tarlac Province. And of course, Tutor Z mentioned earlier, so what are the things that we will be remembering this afternoon? So, since we are now on our week 3, Tutor Z, and our topic for this afternoon is the loss of motion.

Wow! Yes, Tutor Izzy. So, I'll just tell you, Tutor Izzy.

Maybe this is my favorite topic when it comes to physics when I was in high school. So, of course, yes, this is the resource we use. There, to Ma'am Lani, good afternoon.

Okay, this is the writer of Ma'am Renan, Bacolod, and Elma Cordova. Yes. Alright. Of course, in every topic, Tutor Z, like in the past two weeks that we have had a session, of course, we have the most essential learning competency.

What is that, Tutor Z? Well, for our week three, Tutor Markin, everyone, our most essential learning competency or our target to learn is to infer that when a body exerts a force on another, An equal amount of force is exerted back on it. Kumbaga, makikita natin na kapag may pwersa daw na inapply, naturally, yung naalala mo Tutor Markie last time, may natural force, naturally, may kokontra dito.

Katulad ng pagbinanga mo, natural, lalaban yung binanga, Tutor Markie. Yes, tama ka, Tutor Izzy. And of course, syempre, ito yung kasunod or magkakonekta yung topic natin, Tutor Izzy, nung nakaraan.

and also this week 3. So, it's time now. But before everything, of course, shout out to Jasmine Bautista from Santa Lucia National High School, to Luis Errol Faustino, to Anzir Keen Sakdalan, to Karen Adelan, to Emmanuel Citaroza, and to Freak C. Zile Agno. Hello, good afternoon, happy work.

Enjoy having our lesson for this afternoon. Okay po. So for the week one, of course, we have three objectives, Tutor Z. First is to differentiate law of inertia, law of acceleration, and law of interaction.

So what is the second one, Tutor Z? The second one, Tutor Marquee and everyone, is to explain how mass, remember, mass is what's inside the body, not weight, explain how mass affects the object's inertia and acceleration. Tutor Marquee? And of course, our last objective is to know the different loss of motion.

What are the situations for our daily living that we can apply those losses? yes situation and to start our our session for this afternoon so grade eight prepare your papers and notes. Of course, our viewers can also comment so that you can answer your questions and we can see if you can answer the questions that we presented by Tutor Z. For the free test, this is just 5, Tutor Z. So multiple choice lang naman siya.

So read the questions carefully. Write the letter of the correct answer on your answer sheet. Or yung sumang nanonood dating live dyan, so comment dun sa comment box.

Okay. For number one, Tutor Z. Basahin ko, Tutor Marky. Yes, po. Okay, so para sa ating number one, mamaya nakikita ko ang dami na naman nagko-comment. Babasahin natin lahat yan.

Sana walang malampasan. Number one class. Who formulated the three laws of motion? A.

Alexander Graham Belba B. Aristotle C. Isaac Newton or D. Thomas Edison This is easy. We're idols.

Let's see. Actually, Tutor Izzy, we already mentioned the answer in our previous session. There's someone who answered. Joshua Passion. His answer is letter C.

And also Fortune Flower. Ang ganda ng pangalan. Letter C. And si Emmanuel Tarroza, Isaac Newton, tutor marquee.

Okay, so let's see ano yung correct answer. All right, very good. Yes, also letter C. Si Janela Acob, Domingo rin tutor marquee. Andrew Sembrano, Anze Keen, Garcia Saldalan, Athena, Chanel Salvador, and everyone else.

Babalikan natin. Okay. Okay, for the question number two, sigura ako naman ako to tutor Z. So which has the greatest inertia?

Okay, is it letter A, airplane? Letter B, bike? Letter C, car?

Or letter D, jeepney? So grade 8 learners, comment your answer. Hello po kay mamilinda Espino Mano.

Okay, watching from Santo Lucia National High School. Hello po. So grade 8, what is your answer? Sabi ni Joshua Pachon, it's letter A.

How about the others? Again, si Patrick J. Valderrama, ang sagot din niya letter A. Si Fortune Flower, letter A din.

Okay, so mostly ang sagot nila is letter A. So what is the correct answer? Alright, very good, letter A. It's the letter A.

Okay, for the third one, Tutor Z. Yes. So para sa ating pangatlong katanungan class, number three. All of the following apply the third law of motion except... A. Kicking a ball, B.

Rowing a banka, C. Taking out ketchup from a bottle, or D. Throwing a stone.

Alright, so what are their answers? Ivan said A. Joshua Pasion said A. So let's reveal the answer. The answer is letter A.

Thank you very much. Very good. Patrick Vivalderrama, sir.

Anzey Keen, Nick Lumibao-Veloso, Janela A. Acob, Domingo, Frizzis Al Agno, Josephine May Sereno, Angel Jamaica Antonio, and Andre Dupan. Letter A, silanglahan. Very good, guys. Very good. Very good.

For next question, question number four. Which Newton's law explains when a man is pushed forward in the car as it stops? So is it letter A, the first law?

Letter B, the second law? Letter C, the third law? Or letter D, the second and the third law? Okay.

Come on. Come on. Grade 8. So what is your answer here in question number 4? Okay.

It says Joshua Pachon. It's letter A. Emmanuel Tarroza, letter A.

Okay. Sineka Veloso, letter A. Santia Femaludon.

Okay, Josie P. May Sereno. So, mostly, Tutor Z, ang sagot nila is letter A. So, tingnan natin kung tamaan sila.

Okay, very good. It's letter A. Very good, guys.

Very good. Okay, very good. Brian Jake Saliva. Ayan. Okay, Tutor Z. All right, for the number five question class, two balls are simultaneously applied with a force.

So, dalawang bola of... 20 newton. Naalala niya yung letter N newton, diba?

Basta fuerza newton. Dalawang bola, 20 newton ang inapply natin. One ball has a mass or yung katawan niya siksik ng 0.3 kilogram. Yung kabila naman ay 0.4 kilogram.

So medyo masiksik yung isa, yung 0.4. Which ball has a greater acceleration kung parehas na 20 newton ang binigay nating pwersa sa kanila? So the options are, Tutor Marky?

Okay, letter A. They will both accelerate at the same rate. B, none of them will accelerate greater than the other. C, the one with a mass of 0.3 kilogram has the greater acceleration. Or D, the one with a mass of 0.4 kilogram has the greater acceleration.

So, Tutor Marky, we have here Ryan Jake. So, Liva, five letters C, Tutor Marky. So, let's see what the correct answer is. So, let's reveal now the answer. All right, letter.

C. Letter C. Masyado mabilis yun. Daming ating participants.

Kaya nga po, Tutor C. So kung makapasin niyo po, Tutor C, sa question number 5 po natin, may mga numbers na involved. So hindi po bang sabihin yan, Tutor C, sa topic natin ngayon, ay may mga numbers din na tayong may encounter? Of course. Sabi ko nga last time nung nagsimula tayo, Tutor Mark, di siya school year, di ba? Ang math actually is part ng science.

That's why our scientists have numbers. And in the Philippines, we're looking for Newton. And acceleration and the others. Yes, yes, yes.

So let's move on. Thank you very much, Reynid, for your participation in our pre-test. So let's move on.

So just a review. So if we're going to... So we can see here that we have four pictures with our Z.

So the letter A has a magnet. Okay, letter B, may airplane na lumilipad. Letter C, hinihila nung tao yung aso niya.

And letter D, nagbabite. Ito talagang nangakunin ako dito kasi nagbabite ako tutor ngayon. So ngayon, ang question ko sa grade 8 learners natin, ano sa tingin nyo yung pagkakapare-pareha nung apat na to? Yes.

So while we are waiting, tutor Marky, shout out kay Jester. Velasquez watching from Santa Lucia National High School. Also, kay Christine Tubig watching from Santa Lucia rin.

Christian Timothy Dale Cabrera from Santa Lucia rin. Lahat sila nanandun. Pati si Velasquez, Jester, lahat sila nanonood sa atin. Alright.

May nagsagot dito, Jester Velasquez. Sabi nga, 1, 2, 3, Law of Motion. Okay. What else? Okay.

Lahat ba to ay gumagalaw, Tutor Izzy? Kumatingin mo? Yes, of course, obviously.

Pagdating sa picture class, makikita naman natin yung visual clue, diba? Siyempre, pag may nagsasaguan, yung katulad nagsasaguan, Tutor Marky, may tumatalsik, and mapapansin mo yung aso, halos hindi na makatayo yung humihila sa kanya. Yung airplane naman, natural na lumilipad dyan kasi wala tayo nakikita ang ground.

Kung di lumilipad dyan, babagsak. And of course, dahil nakaupo at nakataas yung dalawang paano nagbabike, natural na umaander yan. Alright, thank you po, Tutor Z. So, ang sabi dito ni Joshua Passion, there is motion.

So, correct. So, lahat sila ay gumagalaw. And of course, kapag gumagalaw ang isang bagay, there is a certain force na present.

Tama ba, Tutor Z? That is correct. Yun din po ang sabi, Tutor Marquee, ni Emmanuel Citaroza at saka ni Fizi Zahil Agno.

Ayan, ang gagaling naman na ating mga Grade 8 learners. And hello po din sa mga teachers po nila na nag-sabi o nagbanggit ng, Oy, manod kayo ng tutorial session ng Grade 8. Alos lahat yata, Tutor Margin, yung Santa Lucia National High School nandito. Hello po sa aking mga Tagalusians there.

Maraming salamat po, supporta. So, Grade 8 teachers po kay Sir Pong at sa kay Ma'am Grace Parungaw, hello po. Thank you very much po.

And of course, yaman din lamang nabanggit po natin yung... force ito po yung mga tao behind the concept of force so ayan po apat po sila na pinepresent natin dito so tutor z ang unang unang po dito ay si aristotel yes so si ang konting hapyaw lang naman po tutor z kasi po dun sa kung baga itong introductory concept po Arisotel, grade 8 learners, said that... If an object is continuous, it needs to be applied force.

And when it applies force, it will be faster. That's what Aristotle said. The second person is John Theloponous. He first introduced the theory of impetus.

So, here it says, if the impetus is lost or or decreases, the speed of an object will also decrease. Or it means, the movement of an object will slowly decrease until it stops. Yes, Tutor Markie, I'll just insert it.

For those who... Remember earlier, Tutor Markie returned? Okay.

Actually, Aristotle also applied the idea of impetus. Let's go back to the next slide. Ang impetus class, ang ibig sabihin nun ay yung pwersang existing.

Ibig sabihin, kapag hindi siya gumagalaw, yung impetus force niya ay resting. Tapos kapag gumagalaw naman siya, yung impetus niya habang gumagalaw is yung moving na force. Yun yung ibig sabihin ng impetus. Yes po.

So for the third person, okay, NMC Jean Buridan. So, dito may tinawag siyang mover or tagagalaw. Okay? So, ang sabi po niya dito, motion is possible through a mover that keeps the object moving with power proportional to the speed and mass of an object. So, in this particular idea po ni Buridan, meron na pong bigat or may mass na po siyang involved as well as speed.

So, that's what Tutor Z mentioned, Grade 8, the impetus. Here, the term force is mentioned first as the impetus. So, our next is Galileo Galilei. So, he claimed that even without a continuous application of force, an object can continue to move with constant speed in a straight line provided there are no outside force acting on it. So, Tutor Z. Galileo Galilei contradicts the idea of Aristotle.

Am I right, Tutor Z? Yes, that's correct. Okay.

And of course, the idea regarding that particular force or movement of a certain object has solidified because of Galileo Galilei. Pero may isang tao, Tutor Z, na ginamit. yung idea ni Galileo para po magkaroon po tayong ngayon na tinatawag na three laws of motion.

And siya yun po siya, siya po ay si Sir Isaac Newton. Yes, that's correct. Sir, the laws of motion.

O nga, Tutor Markie, banggitin ko lang dito, isa sa paborito kong laws of motion ni Isaac Newton. Kunwari, hindi tayo magagaling na sa science. Pero meron tayong matatandaan, yung an object at rest remains at rest, and an object in motion remains in motion unless merong pwersang magbabago nito. Okay.

And that is what we call the first law of motion. Kaya yun na natandaan ko eh. Okay.

So, grade 8 learners, nabanggit nga po ni Tutor Z, so an object at rest remains at rest. So, like for example, Tutor Z, itong nasa... Let's go to the next slide. There is a ball. What is this ball?

It's a soccer ball. Soccer or a football. If you can see, it's at rest. That's right, Tutor Izzy.

Now, there. There's a ball that a child will hit. When the ball is hit by a child, what will happen is it will move.

So, when it moves, keeping the goal, the net shooter Z stops the ball. So, from that, this is an application of the first law of motion, which is the law of inertia. There.

Shooter Z, what is the law of inertia? Yes, class, the law of inertia, it is the Newton's first law of motion, yung tinatawag na na law of inertia. Ang sabi ng law of inertia ni Newton, an object at rest remains at rest and an object in motion will continue to move at constant velocity unless acted upon by a net. Force.

So, ibig sabihin nito, class, katulad nga nang sabi natin kanina yung impetus sa tutor Marquee, kapag ang object ay atres, meron ng force yun, pero atres ang kanyang resulta. Tapos, yung motion naman, yung gagalaw. So, basically, magbabago yan kapag merong outside force na makikisali. Tulad ng bola, atres yan, yan na yung force niya, atres, pero may outside force na tumira sa kanya. he moved it.

And while he was moving, there was an outside force that stopped him from moving. So basically, there are two forces, the one inside and the one outside that will be involved. There. Thank you, Tutor Z. So hello to our viewers, to Joshua Passion, there, Law of Inertia, to Manuel Tarroza, Law of Inertia. Yes, and I would like to read this too, Tutor Marky.

This is my idea always, why I love science class. Jester Velasquez said, science is everywhere. That is correct.

All of those, including the Filipino-English subjects, were based on the ideas of science. There. So, next slide.

Okay. So, for our next slide. So, there. Tutor Z, there.

So, there's a man who's in a car. Maybe Tutor Z runs fast. So she ran to the wall. The tendency of Tutor Z is that she ran away when she ran to the wall. Yes.

So what do you think of Tutor Z or Grade 8? What do you think of the man not wearing clothes? Why did she run away?

Let's see if our Grade 8 learners know. So why did the man run away? What did he not do while he was in the school? So while we are waiting, Tutor Markie, we have people from other schools. Nika Dikinya from Canaan East National High School.

We also have Danica Gamula. Good afternoon, sir. I'm Danica Gamula watching from... Rangayan City of Ilagan Isabella, teacher subject, Ma'am Karen Adelan. Hello.

Hello, hello. Ayan, dami lang sumo ko Tutor Izzy. Sabi nila, sabi ni Joshua, hindi po siya nagsuot ng seatbelt.

Ayan, sabi ni Joanna, seatbelt po. Sabi ni Judy, seatbelt. And Anze, Dakeen, Garcia, Sakdalan, Frixie, Agno. Ayan, so correct. So kasi.

He didn't wear a seatbelt. Seatbelt grade 8 is very important because since we are applying the law of inertia, while the car is constantly moving, if there is no outside force, no one will stop him. In our example, the wall stops him. So, the tendency of the person inside the car, okay, he said this, he will run and run.

So, the one who will make the man safe or make him live is the seatbelt. Right, Tutor Z? Yes, that's correct, Tutor Marky.

Okay, next. So, will this vault stop? Okay, so patuloy na umiikot.

So, may nabanggit na ako kanina dito, sabi ni... Who is that? It's Jester Velasquez.

Sir, it is because of the presence of inertia. So, here, it is the tendency of an object to maintain. So, it's inertia, as Tutor Z said earlier, while it's resting, still there is an inertia because it has force applied. If it continues to move, still there is an inertia.

So, and also there is a velocity. So, this is what we call... inertia.

Of course, it may be happening in a straight line. Tutor Z, what is observed by our students? Maybe, sir, who wins the strength.

Because the other one, although she has more inertia, because her mass is greater. The other one is moving, however, the bigger one is smaller. So the bigger one will win. Although we said that the inertia diva class is... Pansinin nyo yung isa gumagalaw, yung isa hindi.

Tandaan na yung pinag-uusapan natin dito is yung first law of motion na an object at rest remains at rest. Yun yung parang malaking elepante. May force pa rin kahit hindi siya gumagalaw.

And then an object in motion remains in motion. So parehas silang may inertia. Magkaiba lang yung state nila. And for that, thank you very much Tutor Izzy. Mas pala Tutor Izzy, nabanggit mo kanina yung bigat.

So it may affect also the inertia, is that right? Yes, mass, tutor, multi-mass. So the greater the mass of an object, the harder it is to move when it's at rest or difficult to stop when in motion.

So there, so Joshua Passion is right, that's what he said. So here, tutor Izzy, there are two balls, one is 300 kilograms, the other is 30 kilograms. Yes. Tutor Izzy, kung na-gets ng mga grade 8 natin yung previous topic natin kanina sa previous slide.

So, sige nga, grade 8. So, yung first statement natin, objects with a greater mass have blank inertia. Is it more or less? More or less, class. More or less.

And while we are waiting, Shira Jel Ampan Tamaing watching from... Hello to Ferdinand Alexis Glorioso from Doña Candlara Meneses Duque National High School. Hello.

And Audrey Mara Luta watching from Raniag High School, Ramon Isabela. Okay, there's an answer. Tutor Marky.

Jester said it's less, Andre said less, Francine said less, Sancia said less, Manuel said less, and Catly said less. Okay, so the correct answer is more. More.

Okay, it's more. Okay, the greater the mass, the greater the inertia. So, it's directly proportional. So, if one thing is heavy, the other thing is also heavy.

So, next po. Okay, Tutor Easy. Alright, it takes, okay, class, more or less ulit ang question. It takes blank force to change their motion.

Madali lang to. Come on, wag nyo isipin mahirap ang science. It takes blank force to change their motion.

Is it more force or less force? Ayan. Okay, may mga sumasagot, Tutor Marky. Si Fortune Flowers, sabi niya, more.

Judy Ann Enriquez, more. Ganun din si Kurt and Andre Dupan. Sabi ni Immanuel Tarroza, more den.

Si Jester, less. Si Jasmine, ano yun, Dago, less den. Okay, so let's see.

Tutor Izzy, okay, the correct answer is more. Okay, thank you very much. Galing naman. Next. Okay, so after the first law of motion, which is the law of inertia, let's move on to the second law of motion.

Okay, second law na tayo. Okay, second law na tayo. So, ngayon, ayan.

So, kung makikita po natin, may, may, may, anong tawag dito? Pinupukol yung lalaki. Yes. Okay, so therefore, my force. So, so from that, Tutor Z, okay, it may explain with this particular picture.

So if we're going to explain this, yung nasa taas po, may ina pa siyang 20 newton sa 5 kilogram na mass. And then therefore, meron po siya tutor Z na mataas or mabilis yung kanyang acceleration. Dito naman po sa ilalim, although parehas po sila tutor Z, grade 8 ng...

ng mass which is 5 kilogram ang inapply po tutor Z nitong pangalawa is 10 newton lang 10 newton lang of course ngayon po low lang ang acceleration nya tutor Z so from that it may explain the second law of motion which is the law of acceleration yes tutor Z the law of acceleration class is the second law of motion na nag-estate na the acceleration of an object is directly proportional or uh to matapat okay the um ratio to the net force acting on it and is inversely proportional to the object's mass. The direction of the acceleration is in the direction of the net force acting on the object. So, Tutor Marquis? Okay po. So, dito sa law of acceleration, Tutor Z, may dalawang quantity na tayong present.

So, dito, taplo pala actually, si net force, si acceleration, atsaka si mass. So, grade 8, naroon silang relasyon sa isa't isa. So, sabi nga dito sa...

In our first sentence, acceleration is directly proportional to the force. So, it means, the higher the acceleration, the higher the force. Like in the first sentence.

So, the second sentence, it's okay. Acceleration is inversely proportional to the mass. So, it means, when acceleration is low, the mass is higher.

So, inversely proportional. sa liwa. So, regarding tutors in the direction of the acceleration, kung saan papunta yung acceleration, dun din papunta po yung net force.

Yes. I-clarify lang natin, Tutor Marky, para lagi nila naalala. Yung mas na sinasabi ni Tutor Marky is kung gaano kasiksik yung object, okay?

So, katulad na nasa picture, Tutor Marky, sabi mo nga, magkaibang pwersa ang binigay, pero same object, parehas na quantity of matter inside that object. One is faster because the force is stronger. The force is too much.

Then, same object but the force is weak. So, there's only a little acceleration. There. So, happy viewing again to Bea Sandra Ronas. Hello there.

And to Tutor Z, we didn't mention you earlier. So, next week. Okay, next week. In week 4, we will award Tutor Z the most active here in our Tutor.

Most active. And then, who is the school that always participates with us. And also, the SD.

Right, Tutor Z? That's right. Too bad last time, no one answered the special question.

Too bad. How much is that, Tutor Z? 100 pesos load, I hope. I thought it was a sauce.

So moving on. Hello. Hello to Kenneth Vivar Calara.

And of course, Tutor Z, because we already have numbers that we are discussing here. Of course, I know Tutor Z, as a review, Tutor Z also mentioned this in Week 1. Regarding the units involved in computation of the acceleration, we have three systems, the MKS. the cgs and the fbs but to thursday in the philippines what we use mostly here is the mks we have here the combination of mass and acceleration to make it force and that is the newton okay so when we will complete the problems regarding acceleration we're going to use the uh this unit the kilogram for the mass meters per second It's for the acceleration. And for the force, it is the Newton. That is because we are in the Philippines.

Tutor Markie is in the class. That is the international system. And you know in the Philippines, if it's international, that's what we will follow. So it's the same.

Okay. So hello to I-Din D. Iglesias Julio from Ranyag High School. You have eight competencies, right? na competent. Ayan.

I love physics, sabi ni Jester Velasquez. Ayan. Okay.

Next, so ito po yung tutor Z, yung formula na ginagamit natin for the law of acceleration. The F is equal to MA. We're in F, that means force, M for the mass, and A for, small letter A for the acceleration. So force, kapag ang unit natin for force is the Newton.

Newton. So, Tutor Z, for us to get the formula, we are going to apply this particular formula. So, I am teaching you this face-to-face, the triangular method, FMA.

So, how do we use this in grade 8? So, if it disappears, like for example, letter F, that means force. If the force disappears, let's cover it. then M and A will be left.

So what we will do here is we will multiply M by A or we will multiply mass by acceleration. However, if... If A or acceleration is missing, we will divide force by mass. And for the last one, what happens if letter M or unknown C, M or C mass is missing? We will divide force by acceleration.

Yes. So, Tutor Markie, let's repeat it. If force is missing, M or A division is missing. Yes, sir.

If force is missing, MA is there, multiplication. So, it's just two things. Yes, that's right. And for that, we will apply this TutorZ through the problem set.

So, now, to our Grade 8 learners, prepare your mathematics ability. So, let's exercise that. There.

Joshua said there's also a math pyramid method. There. no ah physics enthusiast talaga tong si joshua so good afternoon kay kian everyone so watching from pnhs and of course kay ah kay stella lapus from partida national high school san miguel bulacan so we are invading mga tango bulacan tutor z so let's start po tutor z just sa problem natin so dito daw tutor z merong track okay may track daw so ang track ay may be got or my mask now one thousand kilogram so you want to awesome kilogram night on the other national track for the track go Magalha and pop on Tasha now is acceleration is four point five thousand meters per second squared so my own question at Indy to find the net force needed to accelerate the car the truck okay so my own tutors II sempre What will we do first when we analyze the problem? What will we do first? Identify the variables, tutor marquee, or the available numbers.

There, very good. Tutor Z is correct, grade 8. So, let's look for the variables. So, what are the given and what are the unknown? So, here, okay.

These are the given. So, Tutor Z. Yes, our given class is our acceleration. 4.5 thousand meter per second square. Then there's the direction of the east.

So if it's acceleration, remember the direction. Its mass or its body is 1,000 kilograms. So what's missing is the net force.

Net force. Thank you, Tutor Izzy. So there.

Grade 8, you can see here the symbol of A or acceleration. It's a small letter and it has an arrow at the top. Okay, that means it's a vector.

Vector quantity. So, we need it in direction. So, that's it.

Peace. So, now, of course, as Tutor Izzy said earlier, what we're looking for is net force. So, let's go back to the formula. So, what is the formula when we're looking for force through the law of acceleration? Right?

This one. okay f okay f is equal to ma so if you're going to apply the triangular uh concept canina so meron tayong mass which is 1000 meron tayong acceleration which is 4.5 thousand meters per second squared ang gagawin yung dito tutorzi ay anong operation multiplication ayun kagali si tutorzi yun so now plunging the value ayun po yung So now, grade 8. So, what do you think is the answer? Okay, grade 8, what do you think is the answer to our problem?

Okay, to our first problem. What is our answer here? Okay, there.

So, let's see the answer now. So, we're just going to do multiplication. So, ayan. So, 4,500 kilograms per meters per second squared or 4,500 newton to the east. Ayan, ang dami nating tutors ni nakakuha ng correct answer.

So, Tutor Marquee, question. Studyante mo ako eh. Ako.

Kunwari, sasagot ako sa classroom, ano ang pipiliin ko dapat? At yung kilogram, meter per second squared or Newton and then direction? Tutor Z, any of the two. Any of the two because, Tutor Z, the kilogram meters per second squared and then the Newton. Same lang po yan, tutor Z.

So, kumbaga, dito po sa Newton, dinisect lang natin siya. So, yun lang din po yun. Pero, syempre, huwag po natin kalilimutan grade A kasi may nakikita po ako dito sa sagot nila, wala pong direction. That is correct. Ayan.

Kasi vector na siya eh. Apo. So, okay po. So... Alright, before we proceed, sir, we have some new participants.

They're gone. There. Angel May Espillo from Partida National High School, San Miguel, Bulacan.

Okay, so let's move to Jersey. There. Yes, sir.

I'll just explain this because we have 3 minutes to go. Okay, so this guy here applied a force of 2 Newton class to the right. And the ball weighs 200 grams. So what we're asking here is what is the acceleration of the ball?

So as you can see, the unit that we used here is grams. So remember when we asked you earlier about the value of Newton? So you guys, because of Newton, we're using kilograms there. So, basically, kapag ganyan yung sample natin sa problem, all we need to do is to convert that gram to kilogram.

So, we have 1 kilogram is equal to 1,000 kilogram. And if we're going to convert that, it will become 0.2 kilogram. Ayan. So, ayan po. so of course identifying the the given and also the the unknown.

Acceleration. Since we're looking for acceleration graded, we'll cover this. What will happen is force divided by mass. And then the correct answer is we divided this to grade 8. Force is 2 newton divided by 0.2 kilogram.

And then the answer is 10 meters per second. Joshua Pasion, 10 meter per second squared to the right. Thank you, Joshua. So, okay.

It's a bit long. Okay, so there's a box, class. In our third question, there's a box. Then, there's a force letter A. So, force A may apply to 20 newton.

Okay, and then, in force B, there's a negative 10. Newton. Bakit negative 2, 3, Z? Kasi ito po ay Papunta sa left. Okay, papunta sa left.

So, ngayon, so of course, ang given, ayan po, ang given, and hinahanap po natin yung mass. So, of course, sabi nga po ni 2, 3, Z nung previous na topic, kapag may ganyan, nahanapin po natin yung resultant force. So, we're going to apply now the mathematics from the previous lesson na ginawa natin.

Ito yung the answer would be 10 newton okay and then since she's the force okay and at acceleration is 1.50 what we did here is we divided the 10 kilograms meters per second squared by 1.50 meters per second squared and then the answer would be 6.67 kilogram Good, Joshua, passion pa rin. Guru, Tutor Izzy, iskip muna po natin tong try list. So, para mo maisingal na po natin yung last.

Okay, last law of motion po natin. Okay lang yung Tutor Margie kasi naintindihan naman na nila yung second law of motion. Okay po. And of course, ang kakabilib naman pati po mat-problem talagang yung problem solving na ang bilis po nilang mag-gets. Ito naman po sa third law of motion.

Ayan. Kung may makikita po nyo, nagihilahan. Okay. Pero, they are in different motion a different direction rather so as well as dito kapag tayo ay tinulok po natin yung pader also tayo nag-exert ng force dun sa pader okay at yung pader nag-exert din ng force papunta sa atin tutor is ito yung balance force nung last time tama po ba okay yan so law of interaction sabi dito okay uh it states that for every action there is always an equal and opposite reaction so that's why that's what we call tutor marking normal force yes, normal force and for this it is also called law of action and reaction If someone reacts, you apply an action, someone will apply a reaction, but opposite action.

Equal. Direction. And also equal.

There. Okay. There.

And always it should be in pairs. Okay. And there. And again, the three laws of motion, the law of inertia, the law of acceleration, and the law of interaction. So.

So for the post, maybe this is just five questions, Tutor Z. Okay. So, it's just fast, grade 8. So, for the first one, it's the tendency of an object to resist any change in its initial state. If it is initial at rest, it tends to remain at rest.

Is it inertia or interaction? By the way, class, while you're answering to the module, that's from what I have learned, Tutor Marquis. Tama po. Ayan.

So, ayan. Sagot po ni Joshua Pasion. It is inertia.

Wow. Is it correct, Tutor Marky? Let's see. Okay, very good, Joshua.

And also, Emmanuel Tarroza. Hello. Jester Velasquez. Okay. Moving on for the next question.

Okay, Tutor Z. Fill in the blanks with the correct terms. Newton's second law of motion is also known as the law of interaction or acceleration. It's easy for science class, right? I didn't memorize, but I remember. Is it interaction or acceleration?

Jester Velasquez says acceleration. Is he right, Tutor Marky? Okay, very good, Jester. It's acceleration. Very good.

Very good. For the next one. Okay, Lazaro, you did great.

The law of interaction states that for every action, there is an equal and blank reaction. The last one is also a tutor mark. Yes.

Is it opposite or same? Grade 8. There is an equal and blank reaction. Ayan.

Sabi ni Jekster ulit. Tutor Z. Si Jekster. Binis lang ni Jekster. Sabi ni Jekster is opposite. Very good.

So ayan. Sabi ni Patrick J. Valderrama. Opposite din siya.

And the correct answer is opposite. Ayan. Siguro ito na yung last. Okay.

Tutor Z. Alright. Direction. Identify the law of motion that applies in this picture. So meron tayong dalawang magkaibang direction na tutor marquee.

Meron ba tayong option dyan? Wala po. Wala. Tatlo lang naman yan. Let's see.

Anong law yan, class? Yung mayroong opposite direction, tapos mukhang same ang force, tutor marquee. Kasi yung pahanya yun eh. Law of what?

Law of what? Yes. Law of acceleration.

Meron dito Tutor Markey by Josephine May Sereno. Interaction, Joshua Passion. And Emmanuel Citaroza, acceleration. Ano ba ang tamang sagot? Third law of interaction, Jester Velasquez.

Okay. The correct answer is law of interaction. Yes. Pang ilan to Tutor Markey?

Third law of interaction. Yes, so Tama rin si Jester Velasquez. Ayan. Okay.

Okay. So crazy.
