hello rabari welcome back you very good ninth and channel i am saurabh physics maintain today they are every you learn gravity Chapter is easy but chapter Combined with force with motion so thoughts ho this chapter can you meet Difficult but the chapter is easy friend and today they are every you finish this whole chapter in one ko and thoughts what way tomorrow this one shot so welcome to gravity in one shot so everybody hello good evening saturday evening and today they are every you finish this chapter wich mens i am really happy you gas a her Look, we have holidays, but I Where is your gravity mind shot friend? it's ok so what difference does it make it's saturday if it's sunday or monday then let's go what do you say it yes good evening wide Gravitation hey friend now there is force in the dream look dude me video on chandrayaan d what what you are you trying to date something over there yes yes shalini everybody look today i come to office because i have to record something because you and yes they have done it your questions only i have taken it with in it was an mother plus listen to bill reid recordings d videos and Today we will do gravitation of this chapter Big told something really It's important which you know by heart You will slowly understand, let me tell you what exactly they are going to do First of Joe in Do Gravitation One Shot Bill Talk About Universal Doctor of Gravitation Then the value of g acceleration is give gravity what it depends on you It depends on whom it doesn't work on why does it remain different from the value of who lives these things bill talk about and Then comes an unexpected guest in this chapter they will illuminate it tomorrow in class ninth Flotation you will ask why and i will bill tel you care I don't know maybe you are my closest relative Flotation by gravity because of D value of g that something which was both d The topic is butt flotation is not difficult It is important so they should pay the bills which are in this today session is good completely it going to be more than one and half our class take 2 over more than half as you have tu be together you have to be tentatively careful I have heard this and this entire chapter went by like butter I promise you date if you R Every Day Subscribe For The First Time Please subscribe quickly and click next Its bell icon is there, press it and if you r coming every regular press d like button yaar You feel like something great is going to happen We will spoil our holiday on Saturday why are you standing in front of me Like if you believe date today is going you be a ism and if you don't fool like this Like king then wait and I look good so it's ok to do it It will be absolutely numerical I am good I am good ho are you jo of you and neha kana kabhi maa new version Let's start the chapter of gravity the story begins To all Apple Reducing the Upside Story Starters from an Apple The tree and everything fell, fell on my head, fell in front of me I don't know fell from the story toh yahi bolithi hai and he started wandering caressingly if the safe fell Why did it fall down and not go up why didn't you go here why aren't you there why did you drop it down so those thoughts what did you make we are thinking something right so it started with things falling to earth if you have anything and if you drop it with your own hands what happens if things fall apart Ground I would say things are falling towards D center of the earth what are you every study yes very good doraemon gravity gravity will tell you To you IF YOU ARE ASKING WITH QUESTIONS MENUS YOU have i watched one of the concerts last session Have You Lived Concert by Sachin gravity then i have told you are What is Gravity Gravitational Difference don't you see what it is that I am missing you telling me you are there and don't I will change you but make you watch the concept Bike friend they are small but you You say they are small, we will see them later then you leave it, check it, right yes [music] Scattering of light from caterpillars but i wood I am doing it and the molecule is just particular distance right come on forward see something called the universal doctor of gravitation ho ten d dr is formed dr is formed When you observe something continuous and if you make conclusions out of it and you You say, do you know if this is the conclusion I have always seen IT Wickham until someone sees him Disc does not proof if Antil Unlaced you find something which contracts with your hypothesis till you say i love you holds an universal doctor of gravity is Extremely Important in its name How big is the universe? Look at the huge universal doctor of gravity bro its very simple if you have to message me do something which haj matar bil have a mask if you have any There are two months between them and brother-in-law Bill B. Attractive force and bill call it d force of gravity and this force bill depend my fu things what are these yes yes very No good friend our country is not destroyed Everyone has been called ISRO scientist The price of this oil is very less I bill oil you same I oil You in yours what do I think will happen next or so is this right or else is this right you don't Finding a Balance Balance is very important son i will tell you that its ok now listen be careful very good nice Independence depends on few things first on d max of d objects i am telling you devar are you message no so it Bill be directly proportional to d Product of this you will get more message the force will be more right so Directly proportional to the product of max of you objects ok first thing What was your first observation that if I came Increase the mass and this force floods So force is proportional to product of This is my first observation and I write this Next it is inversely proportional to d Square of Distance Where to measure the off center distance I don't want to do this from here The biggest mistake date they make is that we distance ourselves I do a good job with the bar major start from the boundary of this mole d nana nan not this distance no distance between the centers of these two bodies Because we consider the center to be the center of Mass is ok so I am more technical I have come to know about class 11th bill tel you between you center of d max but i am telling you right know that bhaiya this force Depends in Worli on D Square Off distance between dz tu max and distance Where to measure from right from the center D centers such asking how much square proportion You're D square right or A square PIYUSH P OBSERVED IT HOW WE DISTANCE We doubled the force and it became one by four He said, okay friend this is 1/2 of you observe things you experiment And then you say friend this is so much it's been okay yes yes a square apple alright ok Distance is very good, now it is a little combined what ever you have observed what ever you have concluded now this is not a single Let's do it together because date is a scientist you We made a doctor, what does the doctor say? bhai its state date every particle in d Universe attracts every other particle meaning Either you have to send a message to me or you can send it to me in force of attractions now tell me the meaning of being mass You can say that brother is a particle which has mass so if you have one particle it would attract every other particle right with an force which is directly proportional to d product of dewar message whose d is the mass of the particles and the inversal Thou de square of distance betweene dem now This doctor is a bit different, what about you observed what ever you concluded After combining them all, they said right in the state this is just a statement wich you only Is it observed? Yes, yes Piyush, look at the child. If the distance is given then you will become force What will be the square of 1/2d? Force bill force tu 1/4d² so 1/4 ho didn't yougo We will do a lot of numerical on Harish don't worry relax its just starting Hey, listen, it's right, isn't it, my friend? Exactly the same do feather flat n drug force and resistance right so okay tel me is this lock is clear you are it game you Observed you give an hi on this is give you said it unlock it because If you had not seen this, the story would have also fallen Let this blog's lock be clear tell me quickly yes tell me quickly perfectly very good friend ok very easy sir two months is this force is proportional to the product Of this tu message and inversional tu de square of distance between devar tu center just this much is right okay okay let's go very good so we said Force is proportional to m1 * m2 / d² But wherever you remove d Proportionality sign is not a constant for you has to put when you are going class 11 bill b chapter The first chapter will be on units and dimensions Inside that you can see the constant of bill release what is value and why does it come constant so whenever you remove Applying the Proportionality Sign to a Constant does he need constant here It is named G Capital G and its name is Do you know what is the universal gravitation constant? This constant is such that They will come at universal speed Constant Sureli because we know what we did the experiment but waluj I was not able to see it since long I said there is something what are you missing is that but The date does not change with each passing day things in class 11 don't worry today but this understand that friend whenever you remove the proposal n artist and you have to put account ok Now listen G is the universal gravitational constant it is attractive in nature so gravitation Force is such a force that always It is attractive, it does not discriminate damn discrimination this is what i have to say Come to me if you have meat come on right it's you have a mask i bill Its attractive force is attractive which sends Unlike Charge Electrostatic Force what is in it sir plus plus repair Sir North does Magnetic Force Pal North Pal repeal but here But there's nothing like that, there's no affair at all your message always attracts simple ok fine so thoughts that's the same way this is always Attractive in nature but how many people Do you remember force and loss of motion? Tell me this first. These remember force and loss of motion and Specifications What is mass dream in anything If peas are molecules then particles are yes it is called mass okay now mass say you are right ki bhai space time fabric It gets destroyed by gravity it comes but why does gravity come but Not us, we said it first, we observed So I tell you why this chapter is necessary Do you know almost all the missions of ISRO What is going to happen from this chapter Leaving the cap to Chandrayaan brother of calculation should one you have to launch it when you have tu make sir dat it lands on de moon All these calculations are without relativity There is power that depends on this chapter I bill tel u exactly what vasu sir say But for that first listen carefully right? First listen, learn it friend, yes so you be the lesson Action Reaction is between max a and mass b if i ask you late say this is f1 Remove proportionality and get this constant In that it is called ji force of gravity ok very good no you tell me late than f1 f2 forget who forgot about f1 f2 let's say this is only f This is called force of gravity as Attracting be with what sir force f B is attracting A with what force F d only difference between the value of forces direction is different action reaction is different So action is reaction, what did I explain? what did i tell you body a body a Apply force F on body B and body B Apply force F on body A in opposite direction direction is what is getting forced off Gravitation is in between the two, but if i tell you bhai body a kitna force she is applying it on body b you will say sir force of gravitation in which direction in date direction him in direction if you If I ask you can you body be this uplaying ho match force on body aye shar In which direction is the force of gravitation right in this direction in east direction right clear so this is what they are tomorrow Reaction A pulls B B pulls A force was applied but the direction was opposite It is very easy isn't it? Yes I am TR sorry today no, today I will understand it properly, isn't it a mind shot ok that's great a jo so those are the same as RC's f1 is equal to you - of f2 sir mines why brother applied - oil you direction na if f1 was in this direction f2 was in this direction tha so - how will f2 happen this will be mines f2 so That's why force one f one is equal to you - what is the value of f2 what is it d magnitude sir force of gravitation gm1m2 / d² It is very clear, very very Good yes electric field equation yes very good Sir this child will come when we move ahead will the bill increase na, you understand this I know you have a lot of questions right know what this is the value of g welcome to this this is de value look brother everybody listen you be very careful this is something per witch Copernicus Date Very Very Presage Copernicus' experiment inside a hut After making the whole setup, did you sit outside, friend? I should not be disturbed and should not be allowed to go out keep on looking at me silently ok oh this much what has happened has been found the value of g 6.67 * 10 Power-11 Experiment from Way Go this value 6.67 * d power of 10 tu d power of -11 yes Piyush kid will ask a lot of questions questions will come right, just relax very much Good Newton I'm the Spinning King now The revenues are very good right? Yes How did this child come to know through experiment Aaya ji had value, now what did we do? You take the mass, take the distance of each one 1 how much force is there in me square also got added but what is the force k 1 * 1 / 1 It was not happening, the force was something different I said friend why is he keeping it separate Divided, means that some child is born The value of g was ok, fine, so g = 6.7 - 11 now what will be the unit of this if you Think about IT unit, you are easy na bhaiya F = m1 is m2 / d² right? now if you just rearrange everything if you wanna you find d unit of g what will you do What is the unit of force Sir Newton Newton = G * K / Distance in cm what will be the unit of me square so ji newton me square your square de It is called D unit of G This is a very common question, it's a very common The question which I hope you face and you would not The answer is exactly like this yes very good very nice oh sorry i said copernicus what condition me bed maine copernicus ne koper di That was Kepler's and Copernicus's Wright Geocentering Model of Earth Henry Days Kids Slide Direction Thoughts Henry no cavementation thank you very spinning nice cc I got confused that's it it is in Negative cry only child if a force is on this side The second force is in this direction It is opposite right and direction means direction means right okay yes yes correct The value of g was found. The unit of g was found. go me bed it vasant copernicus copernicus Gave D Model of Hero Center It came after Kepler and became very mobile its time for him its henry cavity bye bye D unit is newton meter square It is square now listen this value of ji bole to Sir In the Universal Doctor of Gravitation, Universal Gravitation Constant is its value it independence of what Mediation depends on anything in its name What is the Universal Gravitational Constant Universal world means IT bill note Change Universal Gravitational Constant is not Depend on anything Medium Mass size shop Peas now no one will say that Sir G = F * d² / m² so it is small depend on d no man this is just you find the units that is a constant, it is in depend on anything is clear dikhi ji's value bill note depend on mars not understand note Understand Anything on The Day After Tomorrow yes very good Hi gravitation is there no yes doctor of theory resolution practical from practicals yes go it very good ok brother what is the importance now yaar what is this the importance of universal Doctor of Gravitation and This is Where I Want You and ISRO Scientist I understand which offers are very match interested in all special what is string theory what is What are black holes and worm holes? but you know what happens which happens this something witch come later this that thing It is important that someone tells you that without a friend and clearing class first i want you How will you like Teach You Class 10th You won't enjoy it, right? What did you think you read? The basics are not clear yet Newtonian mechanics is basic and you no joe d space mission no what is date they are doing a warm hole in it, none of this is This is simple Newtonian mechanics this is just simple gravity that's all i'm going to do and you can achieve what this is Relativistic physics comes into play when you speed up You move from the light of black holes you go right so what are the things which Are in theory this is called theoretical Physics right today I am telling you this universal doctor of gravity is good enough you Teach You About Falling APPLES ONLY ONE THINK IT CAN TEACH YOU ABOUT those things which burn the earth date is first second wahi are you not floating in space and you are stick to you if you jump you come Back why date is from simple universal doctor of gravity that moon is orbiting d Why did the Earth and Moon not leave us? I am fed up saying that I am going This does not happen because of Universal Dr. of gravity is what the planets are Arbitrating D Sun Universal Dr Of Gravitation is what they do when their tides are high low tide because of universal drop off gravity so this simple dr can explain you what of this without even going in relativistic physics right yes correct no problem no problem excellent i I'm telling you that this is enough vetiver it is understood til no date is good an There is no need to take it further right now Bill releases once you go ahead now The world and what else is there, right know it It is important that you understand this If you move ahead without understanding this properly then there is a problem okay come on brother so this is d Importance of universal dor of gravitation If you want to write then write IF THIS CAMES BROTHER TELL ME THREE Importance of universal dor of gravitation can you write it tell me yes or no yes hello yes it is a constant because they The Experience Way Experiment yes moon loves her move ahead brother Now let's look at the properties of gravitational Force inside very important question from this There are a lot of big questions First D Gravitational force is always there Attractive in nature always attractive ever don't say this, go away from me it Always Sir come to me right so gravitational force is always attractive in nature it is the weakest force in nature sir and which one force is there i would tell you devar this Electrostatic force is magnetic There are many forces for you sir, different forces but Gravitation is the weakest force sir then it is not there because you are dealing with elders Maslace you are able to see the meaning sun I am seeing this huge meaning is huge thats why you can see the value of this The Force of Gravity Also Hugh Edderwise it's the weakest force in nature right it Exist today action reaction par i told you this mass is attracting this mass with what force of gravitation this mass is attracting this mass with what force Gravitation is equal and opposite is action Reaction body A on body B Gravitational Force is applied by body B on body A gravitational force exerted its independence of medium desant matar where are you you are sitting in what are you are seating in space you are sitting in and ten note matar it country note depend on media Next IT Oy D Inverse Square Dr means this force is inverted proportional tu d square of distance between d tu We have given a special name to this body inverse square dr just fine now deej I hope the property is clear now tell me one thing ask you something yes yes very good same gravity this is what way Observed, now listen to nuclear force Strong nuclear week has also come Nuclear listen everybody let's ask you when you release this object it burns you D meaning when this body is falling dr when this body is falling dr it is falling dr because it is falling dr because Fruit Dr Because Piyush Painting Distance There is a difference between Roshan and this thing, is there any problem No gravity very good sir earth is attracting this object and date is that it is falling dr attracting this body and this body is falling dr what is this reaction of this it is force action reaction right what is it D reaction its non contact force I can't take this question right no very good this object is also attracting the earth with ho match force sir equal force but you tell me something i can see object is moving but wahi is in d earth moving move Tel Me Date yes Mass is very good Force = mass * acceleration IF mass is very hi Acceleration is very low, hence the force yes but mass of earth is huge that is same acceleration of earth is negligible Negligible means zero right so that's what you don't see any effect on the earth right it is correct isn't it very good let's just do this clear yes very good yes nice very good uncle its a good question i have this Question in this question quickly At least it is clear here Universal Dr.Off gravity clear absolutely clear ahead Let's go yes welcome to this question very good let's see How many people have seen if you remember I don't know but please look at him small It is kept well now what is free fruit Apart from this there is a simple funda, it's a very Simple statement IF AN OBJECT IS moving under the influence of the force of gravity along sir force of gravity we Said force of gravitation difference Between Gravity Gravitation Gravitation can be between any tu particle which have Mars The right force of gravity can be between other tu particles wich have max Gravity Gravity it's de special word they put it on Planets or Heavy Heavenly Bodies between the planets and any object that There will be a force, we will give it a special name Given the gravity access, the force of gravity so you can say force of gravity is d bigger umbrella inside it Gravity is a small part of us I specially do this for heavenly bodies Gravity Option Gravity of Earth Ever Heard have you felt the gravity of my phone no force of Gravitation Can Happen But Gravity Only happens and they only do that on the planets fine isn't it yes yes Gravitation is the Universal Think Bucket Gravity is a very big umbrella There is no download gravity is the force between each other particles date is the force of gravitation but force of gravity is life Specific Terms They Use on Planets Heavy heavenly body par deve se ki bhai d force of attraction na im giving you special name let tomorrow it gravity just that much There is a difference, okay fine, let's see now free fruit what is free fruit others think can be set you be in free fruit if devar is only And only de force of gravity means heavenly body falling on earth body falling on jupiter listen fall on it jump be free on right so free fruit if an object is moving inside The influence of the force of gravity let it set you in an state of free fruit now acceleration of d frilly falling bodies is independence of its masses And how did you prove it by living it equal to it is you don't worry i will prove this to you you but right no i am just telling you that Brother it is free but when do we term it i from free fruit they only use it when an body is falling under the force of gravity and gravity alone clear if it's on the same The force is going, gravity means it's free It is clear in the fruit very good you can try the calculation It's not a derivation, let's experiment with it Object give me gravity g no i want you to war new and talking about earth alone right now i Only meaning force of gravity on earth acceleration due to gravity on earth i am giving d special word g ok fine F = this late se up very good so f=sir g mass of earth in mass of object upon this there is distance na this distance and i would say Radius of earth brother earth if it is hair then this becomes r² now meaning is so big if I will place the object on Burj Khalifa done it still doesn't matter right 6400k The discussion going on here is about the diameter of the Earth ok fine so f = gm / r² very good no we have read this too friend they have Also Understand what is this d max i want you to find Acceleration of the object which has large mass How will you get out the bill you find acceleration you are sir divided by am from bill Square you tell me something Universal Gravitation Constant Multiple other planets also found d value of g here is acceleration there is doubt here yes Small Assumption but they are considering you be round right no dat ise same yes what is this r square IF THIS IS YOUR EARTH AND THIS IS YOUR the object is so far the radius of the earth and of another planet you can see there is no planet in which case the r is date is d radius of the planet right so date is r over every clear now listen in d how off meaning is na in d case of meaning IF THEY APPLY D TO FORMAL GIVE VALUE of Gravitation Constant D Universal If there is a gravitational constant, then we know it hey right this is this match mass of earth is how did you solve this match sir mathematics Give the radius of the Earth as per the calculation call it this match ok fine if you put joe Value that amount of data you get It's 9.81m on Second Square acceleration what acceleration so unit bill b me on second square ok clear absolutely right so this is how you found it value of gd actual diu to gravity correct Distance should be from the center of the body objects will be taken from the center of the earth Distance from center to circumference what is it's d radius right No uncle but can it be done if you know your height if you know the depth right then the value of g Nearby Arthrface is taken today at 9.8m Second Square no do you understand why people say this Take D value of convenience at GS 9.8 take it is 10 but 9.8 is the average value of acceleration due to gravity on d surface of the earth is cleared yes right d² = d² is the distance between the center of you objects if an object has meaning It doesn't matter how much you think about it if i give you value done 6400 Km and 1m it doesn't make any sense so I'm only taking R okay so we say near D Surface of Earth Value of G reams of data right okay come on now listen everybody is lying down Told you this chapter can be club very Nicely with motion and with force also motion i remember you read the three equations First Equation V = U + A T Second Equation The equation is equal to 2 out + 1/2 at² third Quickly remember the equation v² = v² + 2VS tell me yes yes Piyush nothing kid do such f/m Neither one went under the M F that's what it is you go m / r² yes isn't it correct very good dees r to three equations so there is nothing in these equations Acceleration give you gravity then if you are Studying objects in the vertical direction then dewar falling on earth falling on moon falling on planets there we I just said friend there was an acceleration here we used to say so let's go, it's all If there is no difference then acceleration friend both are acceleration only na so v=u+ gt s equals beauty plus half gt² and v² = this thing, this particular think I want you Oil U When and how many people need to take plus and minus It is confusing between ho and fu face confusion in this think k sir when u take we equals u+at when tu take we equals you are mine at i explain this to you bill I have explained the motion to you from so many people do you remember tell me quickly yes or no I it doesn't happen yes very good right it's very good you see it means i Happy very good no everybody look brother you take Positive value when motion of D object and de acceleration both r and se direction if your motion is also up Acceleration is also up give it to you brother V = U + GT will come IF U se sir i motion this upward and acceleration give it the word dr u her they = simply i can explain it to you ok hay when download gta v download IF Motion and Velocity Directions from this Upward Mains Opposite is V = I drop the main object like this Moving Dr acceleration due to gravity is also dr Direction from the word I bill him be equals U+GT JUST FINE THIS IS THE WAY IT BILLS There won't be any confusion about help you yes its ok balcony aate d se time what bill b d time difference between d tu balls tu rich what do you think of d ground please solve the options because Object The idea doesn't matter priya do it do it is just you read d question property bhaiya Rahul what does it mean to me what is his name I don't care what brother you want different floor and most building if dropped an important What does whenever question dropped mean? is his Motion There has been a Initial Velocity ate d se time what bill b d time The difference between the two balls means friend it is at a height so it bill take more time i Now understand this question of yours This question is not about gravitation, Vikram motion question sir ho 45 m at u = 0 45 m at bal right u = 0 correct you want you find the right time want u find d time what do u have sir I have S, I have G and I have you Is there any equation that connects these three? be this afraid of other equations which combine dies Three Things Yes equals ut + 1/2 gt² both in how d hair is dropped motion of d hair is in d Direction of acceleration due to gravity Both are on the bottom side i bill him plus it's very easy no problem right so s how much is it 45 = Ut + 1/2 gt² How much is U You can match what you told me Dropped Mains Initial Velocity Zero S It's 45 = ut minus zero in t plus half In this case, how much is 10 * t²? So this is zero. gone right 45 equals half * 10 * t² now You will solve it and see how much will come from 5 to 599 = t² t = 3 seconds 45 minute ball takes three minutes sec what about 80m ball per s=18 me apply d se formula fast sir 80 is equal to u in ut is u0 so it's zero right zero plus half * g means 10 * t² right this If you subtract this what five, how much will you get 5 * 1 = 16 = t² t = 4 sec hey d80 m boy is taking 4 seconds you are rich you are d Ground what is the time difference Is tell me yes or no right Deepansh it's ok child you are here Only one thing is correct, Aarush it is clear Tell me quickly, everybody is yes, isn't it Shruti? Rutba come on move ahead now look everybody has come don't you accelerate due to gravity Waluj 9.8 but you know it is in average Value and what all you are saying sir Meaning, it is not a perfect sphere you R right date is the same d value of g variations what do you mean sir look listen to me this is D center ok is the equator, this is the match 12756/2 because diameter is 12756 ho match one you seven one four by you Radius in d equator is more d Radius on pole and what was the value of yes this acceleration gave you gravity mass of earth upon a square This more radius comes to the pal so can you say Live Poll Bill B Bill B More Give Equator tell me quickly think about it if this radius If it is more then life will be less acceleration due to gravity at the equator Bill B Lee Why Sir Distance from Center The date is too much, so it has gone away right? n body is at a distance from d The center of the Earth is compared to Equator means force of attraction The main force of gravity will be more If it is more then the acceleration will be give you gravity is more at de pole compare You are the center of my heart, so you are the pole in this world, De Equator tell me quickly, this matter is clear This clear earth's shop depends on this hain jio it jio it shop it's little Oblivion kid of shop a little bit such fair no there is a little bit of bullying from cid that's why Yes correct yes Take it out from the value in front, there is no problem Is orange orange is round that orange Which one is flat, like this one pumpkin can you say it is more like What is Pumpkin like or Watermelon? a bit like a watermelon okay its clear now let's go so date is the same what is everybody important thing sir d Acceleration due to gravity and poles this more give acceleration to gravity and Equator If I take a Max sail But he will feel more force compared to you Why is the equator for sale? Its value is on the line. It is too clear right yes karma has come welcome tu dis Right FB Concludes Everything Will Say The Value Ka Gravitational Acceleration Varies With D Radius Where the radius is more there force [ __ ] radius of earth is laser on d port de dat of equator so g is Invariable proportional to radius of D meaning and dates same d value of g and d Polar regions is 9.83 is more than 9.8 and at the end of the poll this is 9.78 The value of g at the equator is low, very good Appropriate term at the equator at 9.78 m The second square is on the Pal Par at 9.83 m What is the second square average of this Sir 9.81 is what we said as the average value of On Earth it is 9.81 but lower at the equator hey right correct what should be the force of gravity if You stand at the center of the earth It's not a trick question but it is like this The question is yes, but we take a trip We really enjoy talking, what This is called force of gravity on a particle which is the center of the earth zero why Same same if you are telling me k sir pole Spare D bodies close to center of D give meaning to the object at the center Closest to the center of the earth witch Infinite yes very good it is five derivation happens, I don't know now listen everybody brother gravity de force of gravity anyway because earth was attracting d object very good director very good nice yes so when you have an object when you have an object At the center of the Earth Its earth is attracting this particle in which Directions like this like this like this and you tell me if i pull apart 10 Newton Hair 10 Newton Hair Net Force How much is it sir, it has been cancelled since then think it's happening in the case of the body which is at the center it has meaning from every side He is attracting me that's why he is getting paid Gravitational acceleration will become zero yes yes very good yaar they have dan lot of sessions you make notes, i will laugh and have a good session on this right Ok Zero is at the center, on the equator, sir Please is it maximum right Now weaver talking about earth every time Recently they launched Chandrayaan yesterday what day You know, we're doing this and it's right because we do it Are you also planning now tell me haj is already on this nasa has done it right so on pay have you noticed if you have seen any of the Video Earth Center Light and Art Way Constructed We do not believe that the center of the Earth is the Earth point object like this yes isn't it very good so that is to say Does the Moon reduce attraction? Moon Attract Lee why because the mass of moon it take the mass of earth this is the diameter of moon so if you calculate using d Simple Formula F Equals GM1m2/R² If will you calculate or else if you Calculate Acceleration using Formula your gravity date is on the moon's radius of the moon's square both the radius and mass of moon is less today compared to earth date The same value of G date is acceleration give you gravity is also less why ji moon Find the mass of moon / radius of moon square if u put jo d value what U Gate 1.62m at Second Square will you do 1/6 of 9.8 16th of d value of g of d earth About the force of attraction on Earth and the moon 16 How did you figure out simple mathematics? Dr. did you know that you are from class 9th Realize this, we have just done all these things with that simple simple doctor wich you are study right na hey that date thank you son read further okay everybody have done mathematics a Value of G on D Moon is 16th of D Meaning Why Because Moon Has Less Than Moon and Moon hj let diameter also right is ok Attracting water on the earth if you release dat it bill fall on d earth no you are telling me that brother the moon is also getting attracted by d earth but same this in d Moon Fruit in D have you ever thought Tell Breaking Down Dr [music] Force tha video tel me yes and no It is a thing of gas, if you release the body IF YOU DROP A BODY IT'S FULL ON D meaning but if you don't drop a body and you push d body in this direction mens u give Velocity in this direction given scenario bill change means look here if you drop IT BILL FALL ON D EARTH IF YOU PUSH IT it bill falls on d earth but travels some Horizontal Distance If You Are Very Close hughes height this is what bill happen if you give it so match velocity you bill rich n Point K Body Bill Start Going In This circular motion this circular motion is what they call it kal s and beat and beat The one who is going to uproot the right and not the beat and the beat means key d text in which it is going around d meaning right so this is happen because you have live it horizontal velocity which is enough you cup it in this circular motion right so thats it no you tell me something bill this motion because It happened earlier that Moon was pushed and He started doing this right centrifuge is different pressure Centrifuge isiodophores wich come in picture when you we are looking at the frame from the moon india i bill not talk today so very nice concept but class 11th right know it today is very good isn't it right, sending optics into orbit you wanna understand know I will give you one statement, you tell me True and Jal de Moon is moving in a circle around d earth means i can see the moon is Arbitrating D Earth Can I Say More Is In yes or no for free tell me can i say moon is in free fall yes Water yes no o nice everybody free fruit definition of gravity on d object Think about it, tell me one thing, if the force of gravity of earth waj not dewar what would have happened This is the meaning if force of gravity because off earth it's not there right if this force this note devar what bill happen more bill se I am going well, remember me in your prayers, right D From Moon Bill I'm going to put IT Bill in these En tangential part it bill note n circular text this force of gravity is what is making moon in this circular the text is right isn't it yes correct true so moon have The song is straight tangently away bye bye tata no correct very good yes it is going away yes That 3.8 cm was thought to be true in its region but the moon is going in a circle it is because it is because earth is attracting d moon you word is d center right This is the force which makes your body move in N Circle, we have given this force a special name Centripetal force is the other force wich is given max n body tu move in a circle dat The force is called centripetal force here But who is providing the centripetal force? hain is provisioning d centripetal force sir force of gravity of d earth Earth was pulling me so I walked in the Moon Circle but it's d only force what was the definition of acting free fruit there should be only one force of gravity Is there any other force on the moon? No, only force of gravity date is the same it is going in a circle so the moon is in free Fruit International Space Station yes everything is clear very good I enjoyed it ok I would like to answer it but I don't know right will the rest of the people be angry at this IF you want i can give you a small concert bye if you ask me in the comment area I will give it to you, it's okay but now this not in session let's sleep gravity goes ahead en centimeter force because of this gravity Working As Sentimental Force What Do You Do see you see moose motion around d earth se think if you take a if you take a what is this hey I got something if you take this Are you seeing this particular thought IF you take particular this think and look at it like this This is how you will rotate it in circles which force is there because of this string This string is there because of which the circle is formed I'm going to think this is gravity this is also example Gravity is between planets and heavenly bodies gravity between you message yes i have given velocity to you are right moon Someone gave velocity to the moon, pushed it like this who did it, had a very big theory that when the meaning was new then on 1st March As the object came and hit the Earth with force If I gave it, I took out the meaning of society and went out to roam It seems to him that he was very wicked Did the moon keep coming together and became this theory Isn't it, we will find out the rest Chandrayaan I have gone to tell you, isn't this okay then centimeter force it x towards D Center Important Center There is some doubt about direction velocity Other doubts Every instant, this moon or these hair if you release d force it bill co in this direction so d velocity of d The instant the particles arrive is a line which is touching a point is They say it is Tacent so d velocity of an particle where will the acceleration happen Tell me quickly it is clear tell me quickly it is clear dude velocity if it is going in uniform circular motion i have tat this tu If you see any body uniform circular before you is in motion it could mean his speed se ho d body is moving with 2 m per second in n circle but this d direction also doesn't change the direction avery instant right so it means velocity change this velocity is changing means dewar Bill be in acceleration because acceleration This can be done by the rate of change of velocity or speed. could but not with velocity Velocity is the product of changing mean acceleration Little do we know what acceleration is used for only you change the direction magneto is from d value of d speed what is this changing direction Changing the Magnitude of Speed to R it will go yes it is becoming clear right yes good Tension quantity Tension quantity is like this This is the direction of Jim who is a Netra scholar We call this current as Norway current Cancer which quality of direction is there It means and it doesn't mean more than that I will tell you later, is it still right? you guys talk SE ANSWER SAME MOON DOESN'T FRUIT YOU so answer this is same meaning result in this you are absolutely fine Is and let u measure ur weight on an awning machine sir no i am fit me weight is showing 70 and you are friend from hey 70 k is not your wait it is your mass so what is the difference Between wet and mask and related oil I am yes yes very good devanshi nice Friend, I am getting fat, my clothes don't fit me you are so what these things happen when you don't worry just have fun The discussion will be long very good Nice Notes Notes There is a very basic difference How many peas are there inside any thing? how many molecules are there so date this what way is the mass of d body it country Note that this depends on the acceleration you Gravitational mass doesn't matter brother mass What is scanner quantity unit? kilogram it is always constant it can never be zero if a body sees this Occupy some space it will bill you some max isn't it okay now if we talk about wait what is this wait it is force de force of Attractions because earth is so blue = M * g because weight is n force F = m * a Blue=MG is the same thing right? IT DEPENDS ON G newton weight is de force and force is Newton so wait is Newton right it where is it from place to place it This zero is at the center of the earth because tell me force is zero center of earth when someone asks you how much you weigh why do you guys answer in a, give the same you answer these questions tell me the truth Telegram Sorry don't worry it doesn't matter It's not fun, that's the truth we like it why do we do it we are dating this is what everyone says you are Right in newton only Because you are more comfortable with KK 5 Give me a kilo of brinjal, sorry five kilos of brinjal Give me five kilos of rice and one kilo of brinjal adi kilo so you who are comfortable with k so nobody tells you bill wait in newton date tel you are the same because you can hear the gk yes that is what a weighing machine actually is Find your weight in Newton but what is it IT Madam Late 9.8 What are the savings Gravitation video is also easy to do at home Mummy's love for taking clothes and saree it is good na ok so wait worries because Depends on the value of g tell me if weight I will measure myself at the equator and at the pole me wait bill be more on equator and more on Tell me soon pal We don't balance the time for Deepansh month For once I remember when Diwali used to be hers yes he tells you max how to compare by The pose is very good, if you want to lose weight Brother, if we go to the equator then there will be a lot of trouble so okay right so wait is an force mass it's mass by mass ten note change ok fine Now listen if weight depends on D Value of G if G change d weight bill change means that i have some late on earth wait if i call you di moon me wait bill change that's because moon pays value to it what is the difference sir value of g on d moon is g / 6 is not 16 meaning so you are you wet bill be one sixth you are wet bill B16 on d moon right so thats what you are Wait Bill Wickham 16th on de moon is clear isn't it yes ho can i measure mask when you mask you can compare it to what i am living here It is there and I am living here too, in both places I am dying means my life is cancelled now are you comparing mass and thoughts this being balance yes you are right shaurya strength six Times will come brother [music] if the value of gravity of earth Suddenly Wickham Zero same think if an body is going in an circle because of this thread if you cut d Thread D Body Bill to Straight Intangular Direction se think if de moon is going in n circle but suddenly d value of n force of gravity of earth wikham zero what bill happens is going on is going on it is going on it is going on zero This is how straight tension moon will make the IT bill ok fine let's talk about the question brother which of you solve quickly if you are 50 k on earth surface what are you on an Planet witch it mass one fourth times and radius half in comparison tu meaning good question means this one question this I will ask you 50 questions above it's a pattern if you solve this mean you can solve 50 100 questions more like this solve it easily come on Oh no, it is coming, there is not that much difference come on friend we are talking about pal yes if you Ko tu act antapik and north sail alaska alaska let me talk bill Time session in d on d channel ho tu make n make a slide projector it's good will this ever happen Hey, you can live your life comfortably You will leave and 100 generations will follow you And when we go out, maybe something will happen, it's okay Yes 12.5 DVD Lot Of Deez Deepa it depends only on ho match mate region depend on anything you are waiting no it doesn't matter and wait s50 on earth if you take the moon me me battery if u take d to be a machine On a Different Planet Which Has Mass 1/4 Times of Earth and Radius Half of D Earth what bill it read your mass there Your mass will tell you how much A wait in front of us think what we are going to read what is your weight they say 50 ka date this is exactly this is a real life Question It doesn't matter if you do it, but wait I won't get it but don't worry you miss me I will tell you Listen, I am making the same mistake as many people do. Well I'm telling you look everybody Maid 50 K on Earth Surface on a planet which has mass one by four Times him on the planet how much difference will it be If your mother is showing 50K what does it mean What is your weight on earth 15 * D value of g honors hai na this is it your wait on meaning is very good know what is its value of g on this planet g = M/r² now he is saying that friend M is there na date it 1/4 times of d mass of Earth which is R radius is half of D Earth r equals 1 / 2 of r a no value of acceleration due to gravity on earth is how much it is sir gma of our RA square now put this valuj n in it will come on d planet it yes multiply by sir 1/ 4 m apn 1/ 2 R A's Hole Square in It's done so what are you getting sir ji your r a² d value of acceleration due to gravity on this planet is equal to the value of yes on earth se a gaya correct yes aditya They have used the simple formula r² carefully look right yes very good i know 15 you I told you brother on this earth the value of weight and match you can see this is coming out you be 50 right? So we told you how much the earth weight would be 15 * Now let us see the value of g find that bhai ho match it with d value of g varying on this planet and for what date i have She has nothing from the formula Max off this planet is 1/4 of earth radium of this planet is one by two of d earth if you Pat dees value u bill relies care d the value of g on this planet is actually Equal to d earth means d value of weight bill not change you bill exactly the way d what will be the answer 50 your weight bill read 50k only right na Square na bow no problem Shouted Let's ask the next question which is following It is written on both surfaces of the moon and surface of d earth weight of d times weight of d Best Note Mass Of Ds Note Gravitational Force I went there and said I will install it exercise i want you lift heavy weights you tell me something because on how many matches you have schorler quantity So that is why the weight of bar bill has changed because Depends on D value change because it is wait it bill depend on g gravitational force right so if you think about it if mother Take Here I used to lift 10 kg from you right moon so you know what will happen bill you bill you bill be able to lift 60k right so moon pe kya hai you can do butter yes Oho absolutely yes very good change is great isn't it now this is d and off gravity half is gravity over is it coming back even tell me any other problem Nice Dates True I Respect Date Kids You guys are playing outside, you guys are studying here I know but it's only today you can enjoy tomorrow Tomorrow is Sunday, tomorrow is your holiday have you returned from school why is it simple it is force in time for how long The amount of force applied is called its impulse Ft it is equal to change in momentum Rest I have convinced you about force and loss Look at that guy in off motion, he has momentum Concept Bikes Read it friend, if you like reading then The external knows that you should not say this Like reading extra, please read this walk quietly come on trust impression Everybody listen to you Mick a little stunt pressure I tell you a little nothing it's Perpendicular force to surface devar was d chapter called s in class 8 Force and pressure, oh, have you read this? you have studied in this thrust is force what type of force which is perpendicular to the surface we have called named it thrust isn't it yes very good so thrust is d force like perpendicular you d surface if trust is force unit bill b newton what is easy pressure its thrust force acting on unit area right date is de pressure so unit kya hogi Sir Force your area and trust / area means newton me square was de scientist on hai name they have jivan d unit pascal okay so newton per m The special name of the square is Pascal, okay isn't it force this was good yes what is this For this is acting perpendicular field date This Yes Explain it is multiple times na please watch it and Adverwise Vase De Concept IF YOU THINK ABOUT IT INSIDE AN Liquids are special if you are swimming pool I go and you give me the bill, I release it There is pressure on you to perform, right? no the water pressure is ok so de pressure in liquid it action which direction sir HOW TO KNOW IF YOU TAKE A BOTTLE AND YOU CHOOSE one level and you five hole cut cut cut cut you Bill release from debt level d water bill reduce out equals in which directions mean pressure from here right so pressure comes in point in liquid is equal to this is acting in order Directions If you have to give it to me in this liquid, then you are as much If you go deeper, the pressure bill is increased, right? IT BILL VARY WITH DENSITY IF LIQUID There will be more dance if it is liquid Dangerous pressure bill should be more correct to basketball also first dr I have wooed her well so everybody Now I had actually read the extras. get you this formula in class earth only This is how the pressure is coming in front of you n depth it is rozi ha ro means sir density yes this acceleration give you gravity haa this D depth means depth means how much from the top below is right this is d ha right d only These chapters of Reason I Can Think Of why flotation in your gravity we know because of this ji, this ji is No, that's why you have this chapter If I had not gone I would probably not have come but now I am not hating because of this, don't hate me because of this right it's a small topic yaar it's easy Liquid depends on its density yes absolutely Do you like swimming or have a friend or try it like me because i don't know swimming but i have trade then i leave diya i sang up it is true i have no idea Vegetation hey I had a headache So I gave up Do You Swim Do You like swimming you have real height of Realised it doesn't matter yaar when you are inside d tal na if you Jump, you can't jump too much like this isn't it you fool lighter vile swimming right no very good so what do you fool lighter same do you fool lighter because there is water in dewar is a force wich is acting upwards he Aditya When you go to take a bath, how many people take a bath? I tried this and don't tell any lie nobody tells me an live over her you me try it this you have a bucket full of water and you have your mug you bill take d mug you bill cup it upside dr and you bill push it in side d how many people tried did you do it for sure because I I used to do it friend right, when they used to send me to take bath I thought it was half an hour instead of 15 minutes Why are we doing this, we used to have fun you are doing good good, do you want to put it in your mouth sometime Whatever these things come in the water, you do them isn't it right yes yes obviously very good Experience by Object Immersion Liquid It means when you push something in an Liquid You Full Resistance D Liquid against you d liquid apply a force in D is upward direction correct right? so when you immerse liquid inside when You immerse yourself in a solid body inside liquid this upward force acting on d solid because of di liquid is upward we call force so now think from ther and point force rd bye and see it also d se think what This up thrust bond force happens and Bond C Say Yes or No and si se yes no Pressure Relief from pressure depends on death value I still do it, it's very good Property of the liquid which applies force on d body immersed in it sona si hai The name of the property but force is i.e. and point force okay don't get confused come on now look now first and bond force so if I said come to the level and this if you remember concept bs dude i have donation This derivation in d concept is BS right at a good level so what is the pressure if you are relieved then it means you can do it brother Pressure means area, if we do it People will force the force to be cancelled but d the difference is pressure on the top most point and pressure on bottom most point Pressure on d bottom surface and pressure on d immense surface bill bee say yes or no tel me Pressure on the upward surface of the date block and pressure on the downward surface way bill B says yes or no yes no wahi sir depth is different this wala surface So it is on h1, the one below it is on h2, that means Pressure bill be different right so can you say K difference in pressure wood B bottom -P top If you make this now thar know what is it what is it first Direction more den di force on top surface sir wahi Because pressure and top surface was li da Pressure on bottom surface so I can say F = sorry f / a = p so f = p * area right Now from area of top surface in bottom surface Both of them are square, right, so I say P bottom mines P top in an ise d force off ther so what is the pressure rosie ha right rosie h2 - h1 * a Rosie h2 - h1 look carefully brother PM -P Top in area so p bottom kitna hai sir rosi ha so ro ji ha you mines ji h1* area it's ok if you take rose out yes h2 - h1 * hey this h2 - h1 what will you do bill you get this right you bill get this tell me once what is this the volume of an cube what is this the volume of when it denotes density How did you come Why do you know right this is your cute right This this a and this a what is the area sir a² What is your height and what will be the volume sir a² * a date is the same as d volume no it is there then what kind of area is this area is IF YOU MULTIPLY THIS AREA BY THIS HEIGHT Density of liquid multiplied by g Multiply by volume of body this is the force of Force Tell Friend, wait for the atmosphere that is around you because of that is it right or not yes Let us go Look now there is property na so and upward force is Experienced by the object immersed in liquid right if any body in liquid If it happens, it will be applied on him, give upward force upward force is called san first so now look carefully friend if IF body is this Floating Atting D Surface If a body is floating on the surface ho money forces acting on this body is How much force is acting on the body which is pulling down seconds it d Force Consolidated yes very goodbye My name is Saurabh, tell me mother why is it did it I am relieved so I forget about it yes yes and right now listen that don't give cancel if tell me if this force and this force they are competing with each other if body means it floats on the surface means this force is less and this force is More if this force is more then the body will flood yes correct if any body floods it means Gravity pulls pushing up gravity is pulling dr if body is floating on d in d in d liquid means gravity is weak Upward Force Strong Downward Force date is gravity is taken and date is when d body bill float okay we can speak Downward force is line point force Find if both forces become equal meaning D weight of d body force what bill happen you take the body keep it in water or any liquid where it is left dog she will stop there quietly if you take this body you cup it over every bill st over her if you cup this body over her and State IT Bill stays every right, this should be in it It will go where you leave it, it will stop there IF D weight of d body is more den for then what will be Gravity force is stronger and bond force this light week give what bill have IT BILL SINGH CORRECT VERY GOOD VOICE ISE your right because density is more than it Depends on density simple welcome when bill body sink wait it more right so Based on this particular thought principle Here comes the Archimedes Principle Gravity Acceleration Gravity Multiplied bye d volume of body na this is where we drove Do you remember, tell me quickly if this is clear? it will become air soon tell me yes Yes It is very easy to get a particular thought clear, isn't it? yes now listen r km Flood IT Experience Equal to the weight of the flood in IT Once IF YOU HAVE JUST A BODY WHICH IS IRREGULAR Do you know whose body to remove? for sir cuboid do you know why do you know Random Stone Ho Can You Find D Volume of d story anybody This is not a trick question it is real QUESTION IF I GIVE YOU A RANDOM STONE and s i askku and i ask you what is d The volume of this stone may be yours but date I will tell you a universal very good story, yes put it in water its length is ok yes almost is almost behind very good dhanush good See if you take a vessel yes very good friend sorry nice if you take a vessel wich haj water field you d top right you that Story Sunny Hai Have You Hard Date Story Do Hungary Devar vaj en crow witch was hawk na thirsty It was there but the water level was very low, what did D Karo Do D Karo Started Putting Tables in d water what happened water level race it started to happen and when d level reached over every de crow was able to drink to water hai no yes correct english do ok fit in her brother IF YOU HAVE WATER FIELD IT TIL D TOP and when you put a stone in the water Bill Come Out As Much As Water Bill Can Be Displaced Volume of water bill will be displayed on date D Volume of D Stone It's clear right so if an body is Fully Sub Mist Amount of Flood Displaced is the volume of the body say if n body is full sab mast can i se dat volume of body is equal to you volume of liquid Oil Me a body is fully submerged can i say the The volume of the body is equal to the volume of Liquid Displacement Yes or No yes and no command yes No it is this match water and if put that stone inside db girl and me water level is This Match This Extra in Increase volume volume of liquid is equal to D volume of body yes isn't it yes His Formula They have derived it properly, yes, right? aditya date i have you do not worry correct right so that was the same d point force is Defending on the density of liquid ho match volume of liquid is displaced Multiply by d value of g then If anyone has any doubt, watch the concept bike in date i have lived you on one level And I have given you the level, right? Easy story which story is this and forgetting First let's ask questions, question questions Question of volume 120 cm³ is immersed in an Aquarium ahead shone calculate d point Force Acting on D Submarine and Tech D Digital water is one gram present or just remember the density, just remember the density of Water is measured in one gram per centimeter and 1 kg per but when am I The timetable depends on me, friend. where can i go to play badminton After that I take some rest and study We do it on other weekdays, friend Office is at 10:00, after that what are we Let's prepare, do they have to go to Patna is it how to patna when is it patna what is it We have to fly Chandrayaan, we do all this We people yes yes I am not working listen to me so the volume is Volume of liquid displays equal to volume of Body Energy how much is it aa [music] nor how much did we get think about it IT CAME TO ME 120 grams multiply by 10 newtons per me Square [music] yes very good So that was the correct answer, this is 1.2 Newton it is clear right yes sorry Tel u ki bhaiya which body will flute Which body will sink they have a very simple funda first you check the density of Body comparison with the density of the liquid If the density of the body is less than that of the liquid Density of body is same as density of liquid IT Bill Float if density of body is equal to density of liquid it is an suspended body I mean you cup it here it is bill st every you cup it her it bill ster inside d Liquid if the density of body is more Density of Liquid IT Bills is Sync Right no thank you aishwarya Hey Purvi, today it got recorded. it will take a week Yes Why does Piyush do this because he drinks water It displays We make Shiv empty from inside, that's it Is practice one point Brother, if you want to compare the density of the body Density is low, meaning flood will be equal meaning it will be submerged, if it is too much then sun it I will go right and take this to Devar this one more A concept called relative density nothing is related road date is relative The only difference between density and you have one single word and one single Quantity One Single Numerical Value Wich Bill oil you's brother body bill sink and flood why sir do you know the meaning of road what is it d ratio of density of liquid to d density of water Now take oil and water, oil flattens the skin is it not the density of the liquid of water is what they call related Density of Liquids Right So For Example mass of 100 cm cube of water This is equal to 100 grams and another one is kerosene Mass of hundred cc is equal to 80 What is its density in grams? Everybody density of kerosene bill b sir 80 / 100 Density of water Bill B Sir 100 grams per 100cc related density of Kerosene bill should be matched with density of kerosene its density of water is equal to ED/100/100/100 IF YOU SOLVE IT you got bill 0.8 0.8 aa just looking at it this value of 0.8 you can say yaar this to It is a lighter so it will flute kerosene oil why bills float in water because are this lee de one is na if you have mercury mercury But my favorite cubic centimeter is the volume 60 gros so its road data related to it What is the density 13.6 more de one That means IT Bill Singh is AG right? Yes correct. The child follows the exact timetable on community post and also on telegram right so with this density i want you to oil You brother, class ninth is on gravity only this match today they have dan fu questions but lot of theory but date was I am so important to anyone else Problem in Gravitation Watch Today Session very sensitively besides i have lived you Special Concepts If You Are Particularly So if you have any problem with any topic, watch two small Small session, all your doubts will be cleared you have everything left now It is yours, it is ours, the path is short It is your duty to show it and take it to the temple Dialogue from oh my god i have just copied it is ok so it's yours when you come to study Jump only teach you my less is less than this me when is tu make sir dat you practice more We will do these questions before reading them If you don't come, then you won't enjoy it I won't enjoy it so head read this properly understand this chapter properly what about you have tel me d Comment area: Talking about notes, so Notes became a proper proper sequence for and yes I know human you me not be You will get Getting Fool chapter notes You will not get session vijay but its notes I will go to telegram and relax, it's fine right yes two-three questions sorry now on one homework u IF IRON IF D Density of iron is more than water the ship floats you answer everything else is ok this is d homework question but u are ok fine alright it will be 7 o'clock friend sleep very soon Everybody with this gravity chapter is don u study properly because they are are you going to do good question exam ha Right inside the next session bill be on Solving questions before date if you study very nice you bill fool very empowered Otherwise you will get into trouble Read, see the concept bike, see you next I ask you, will it be fun? d best see you next time Bye
