Units and Measurements Overview

Hello children, good evening everyone. To our Plus One Onam exam series Welcome to the Triple Dhamaka series. Onam for you, my children, the examiner. This is offered for the exam. What do we do with a series? I'm leaving with you already yesterday. It was said that there will be seven in the live event. Complete Plus One in a day Let's finish studying the Onam syllabus. The first day's live broadcasts are underway. Already started 2:00 Biology and Computer Science Live Physics was first live. As part of this triple Divaga series Physics' first live is here. You are going to walk so maximum. Children need close support during this time. The chapter we are going to study live Units and Measurements In other words, in our Plus One Physics The first chapter is the simple chapter. Not only is this what we are learning today There is something special about a live 7:00 we What should we do once we start? Children in one hour, that is, eight What should we do within this hour? Just finish studying the chapter. This will be in just an hour. Units and Measurements We have completed the chapter. You are going to study. How can someone spend an hour? Learn with your children in today's live. What are we going to do? Discussing unnecessary things This one chapter is not going to do it. From the exam perspective, that is What are the exam topics? I'm going to ask that one. Learn from perspective It is unnecessary to go. We will change everything. Especially in the coming days What do you do too? To learn unnecessary things Things that come up for the exam that shouldn't be taken It's all about focusing and studying. That's what we need to do today. Going to do it live but it's... Not an easy task, one hour. So this big chapter is a small chapter. Nothing, a little, essential, medium level This is a chapter full of chapters. If you want to finish teaching, your I need your support, sir. How to support children That's all, you too should stand by the door. Okay, this is an hour. No distractions, family members. Say, say, stand aside. And then with complete focus. Questions for you to see. When you ask anything, just ask in live chat. Quick quick quick answer Come and get full of energy for this one hour. You should stand still and I will stand with you. I tried my best but yours didn't work. What should you do from the side? Come to your house and tell you I can't say but Write here and I can tell you. Maximum energy, maximum focus. You spent another hour. If you're ready to do this, this is a chapter. You won't have any trouble in the Onam exam. And what can we learn from this one chapter? Even if the question comes, you will be 100% Answer the Onam exam with confidence. Okay, children, that's all I can give. Just to say, nothing more to say And another thing yesterday I will announce the winner of Question of the Day. It will be selected then. In yesterday's live, we discussed the Question of the Winner of yesterday's live today Because it never said there would be There was no question yesterday, but Even then, what am I today? Yesterday's live will be done. From the comments in the comment box Five people will be selected. What will happen to those five people's children? There will be a cash reward, sir. How much will the cash reward be for the children? Depends on the viewers of today's live. I will do it today on this live. There are now 600 people watching. Yes, but those 600 people are 1000. Once that is done, what is 1000 divided by? We will give cash prizes to the following people: For five people = ₹200 each The child will also get it, but A minimum of 1000 people must come live. But let's talk about the cash prize. Negotiable or cash No price, so maximum live. What to do to bring in the waivers? What should you do with your friends? Must share on Instagram Cool status in our tamna Leave everything and status etc. A cool thing to do in our neighborhood. Put some status on me, Alan. Tag sir and Archana Miss too. Do it and then maximize. Friends and not only on Instagram What do you do on WhatsApp? Send a message and share it with them. Come and learn, okay, that's all. All you need to do is cash If you want to get a prize, 1000 At least we need viewers, then something else. You can do it. What is an easy program to make children like you? Those who haven't, please like it on YouTube. Please promote yourself a little. Okay, I'm ready, that's all I have to say. Let me announce one more thing, children. These are all yours last year. Aren't you seniors now in Plus Two? Children studying last year In the Plus One Agni batch of the examiner 520 out of 520 studied, 100% is the maximum. The Kerala toppers who got the marks are All of them studied our Plus One Agni. In the same batch this year Going to study dedicatedly For all children, children beyond this What can we do about this? From our fire batch of the year Let's make it because this year there will be fire batch onam. After the exam, we will have a fire batch. What are we doing now that the new feature is free? I am going to give it to Agni who joined the batch. For all children, that is, for you. Recorded classes and learning videos Previous year questions and all Facilities and Examiner's Book Set and everything with extras There will be a daily live class. If you say daily live class It won't be extra class. Your chapter itself was taken again. In the way that you give, that is, to you You can see the full as a recorder. What else can you do besides studying? You can be a recorder. Live for those who don't like to study Even so, each chapter is a lesson to learn. What will you do if you have the opportunity? I am going to Agni after this Onam exam. Okay, so what are you going to get in the batch? If you want it all, quickly. You take admission in Agni batch. All said, you will get the books too. Plus you will get features like this One more thing for you. Okay, so this one will happen. The thing is inside you. If it creates excitement, Put the fire emoji on your kids for a while. What am I going to do, waste? To start the class there. Units and Measurements is coming. Chapter one is our hour. Time is complete, we are ready for the Onam exam. The first one will be paid for. Question: A question like this is yours. You can see it in the Onam exam paper. It is possible that seven fundamentals Quantities will come in seven SI units. Don't those seven SI units exist? There are seven units to write. Sometimes you don't have to ask. I'll ask one or two questions, but in this Just ask me anything, okay? So learn to write quickly, you're already ready. Everyone probably knows. Anyone who knows, please join the live chat quickly. Those who don't know, learn to call their children long. SI of the said fundamental quantity What is the unit for you all? Do you know what a meter is? Children, what is a meter? We can write Mater A as Mater A. What is its symbol? What is its symbol? Just write the symbol M and you're done. The program is over, ready, next. What is the SI unit of mass, children? You all probably know. What is a kilogram? Children, kilograms. What is its symbol, children? You may know that KG is There's no complication in it, it's simple. Something that is taught in small classes This is the S of Next Time Time. The unit of measure is seconds. If you write "seconds", you can't write them. Simple enough, no extra S needed. There is only S and C. There is no "I" or "S" only. So if you say SEC, in the live chat I see, please correct me. Mark. I didn't get it, did I hear it in the exam? SI unit of electric current Ampere is the son of Ampere Ampere Symbol Capital Letter A It's not difficult, it's simple, children. Next, tell me the temperature there, Alan sir. Is anyone on live? Alan Sir, Alan Sir Yes, didn't you break Alan sir? I'll hear from you tomorrow, okay? Tell me you're ready. The SI unit of temperature is the Kelvin. Children's symbol capital letter Kelvin K is the capital letter K. Next Amount of Substance In chemistry, we study the mole and We measure the size of atoms and everything. Do something will be in a unit. What was that unit for everyone? You know, it's M O L E S, right? Moles, its symbol is simply M O L. Listen, there's one thing you don't want here. No need for pleural, just MOLE. The only thing missing from the symbol is MOL. That's its symbol. No problem, Last Luminous. Do you see the intensity? Don't you see, I'll show you down. Don't worry about the luminous intensity. In other words, it measures the intensity of light. A unit is a unit of children, its SI What is the unit? It is candela. The children learned the symbol of the candle. The CD is simple, children. Ready Seven Fundamental Quantities Seven Learn SI Units and Their Symbols Put any one in the exam. These seven fundamental lexical questions will be asked. No Alan sir, okay, seven fundamentals. Quantities plus two extras There are quantities of them and you. You should study units, not just units. We need to learn their definition so that we can Let's look at the children one by one first. Who is in the question itself? What is it? The SI unit and dimensional formula Off-plane angle right it Definition A plane angle is a He has an extra quantity. SI unit who is dimensional formula Who is the definition of who is plain? Angle is a regular angle in a circle. Isn't the resulting angle called theta? Don't you study at Max? Theta sine theta cos theta a Of a circle or a triangle The regular angle formed inside is Our plane angle is OK to D angle. Angle in two dimensions is okay. If so, what if we say food? What would be nothing here? Isn't there a length of the arc? This is Who doesn't have the length of it? Let's call this circle L. Let's call the radius R, that's how it is. When we say theta, we mean a plane angle. In other words, it is simply equal to Arc Length Divided by Radius Plane Who doesn't have length when it comes to angle? That length divided by the radius of the circle. No, if Radius does this, the program will So how do you write it as a formula? Theta = Theta = Arc Length If you say L radius, who will you tell? After this, grab it and put it in the box. The program is over. The program is over. This is it. The definition of a plane angle is as follows: Say in English: Who has no children? What is the ratio of length to radius? Just write down the plane angle is the Ratio of arc length to radius Arc length times radius is not two. That's all there is to say about radius. It's clear, should Alan be banned? How many people say Alan Sir should be banned? What about those who want to ban Alan Sir? Make children with a horned emoji on their heads. Put it on, ready, that's the next program. What is this person's unit? Is the SI unit the SI unit degree? Sir, if you say 30 degrees or 40 degrees Is it degrees or not? Don't get me wrong, it's radians. Its SI unit is radian. Has anyone learned the symbol for radian? Did you hear the symbol "rad"? Okay. Next What is dimensional formula no Dimension or dimensionless is that? You should ask in the exam. Quantity with unit but dimension Non-existent quantity exists. Does it exist? The unit is doing Without quantity dimension Quantity plane angle is a Example, right, sir? So that's it. After asking, you should say that. There exists a No problem, there is a unit dimension. No, there's nothing wrong with that. Things about plane angles What you have learned so far Is there any problem, children? There's no problem, clear it, children. Sir, is it Alan Sir? Everyone is like he says. If it's clear, say "Clear, sir." You should say "Sir" not "Clear Sir". Isn't that what we Malayalis say? If so, without a plane angle There is another supplementary quantity. When you say supplementary, it means extra. That's all, who is he, his children? What is the right angle? S Unit and Dimensional Formula of Next is the solid angle and also what Easy Definition Definition Exam You might ask, who is this solid angle here? The angle formed inside the circle is A plane angle is a regular angle, and so on. You are taking a big spear. Imagine that football. Imagine the center, from that center, An angle to football Isn't there a 3D angle? A cone of our cone ice cream Ice cream is made here and there. Isn't that 3D angle? What do we call this angle? We call it a three-dimensional angle. Solid angle Symbol of solid angle Theta is not the theta of a plane angle. The symbol was the symbol for the solid angle. This is the symbol, this is this, this is the Omega. Why call your children Omega? Call our Om, three Om, four Om. Isn't that Om that says, "Ohm?" That symbol of Om? Omega is his symbol, that's all. That's how you see this solid angle, sir. How do we define children as a The spear has no arc length. A spear will have an area of What is on the surface? It's not the length, it's the area. What will happen to this area? Call me, just don't call me Area. We will call the intercepted area That's all there is to it, the intercepted area. The area itself is OK divided by you. Think about it, the radius of this spear Isn't there a radius of six? Is there no radius because of that radius? Sir, what needs to be divided is not a solid angle. That is, the intercepted area above The radius below is not the radius of the radius. Square will come, okay, square will come, clear. It's clear, my children. The square of the radius is clear, children. You will probably come to know what I am not saying anymore. How do you define it, sir? It's simple. What is the ratio of a solid angle? The square of the intercepted area The ratio of the radius to the radius is It is the ratio of the square of the radius. So solid angle is the ratio of Intercept Intercepted Area Two Square of the Radius of the Sphere The program is over, no problem. That's how it is, sir, in formula form. Nothing to write about solid angle. Simple Omega Omega = Intercept Ariane Call it A divided by the radius. The square can be written as r². This is his The formula is not difficult yet. So, children, the next question is, what? Is this SI unit the SI of this? Whose unit is the radian of a plane angle? His SI unit was his children. Who is Sti Radian? Who is Sti Radian? Same as Radeon but with Stay. Add stay, add stay. Radian, no problem, Alan, my children. Sir Alan, can you restrict it? When are you saying something wrong, Alan sir? Can be fired Okay, ready, what is the next dimension formula? What is the dimensional formula for children? Write dimensionless or dimensionless. This one also has units but no dimensions. These are the things to remember. From the plane angle you It is important to remember that If there is no problem, let's What can you do without wasting time? Let's move on to the next topic. Significant Figures Significant Two to find the figures The main rule you need to know Look at the first rule, children, decimal. It is a joke to say that a number is a decimal. Is the number a decimal or a decimal? The rule is number one, it's very simple. Find non-zero non-zero Find the person, put the bracket, zero. Otherwise, find someone. Find and put the bracket. After that, everyone is significant. After that, everyone is significant. It's significant until the end, so how much? There is a significant one, two, three. Four five six seven eight eight This number is a significant figure. So what is the decimal rule, children? That's all, the first non-zero. Find out and then to the end That's how the decimal is, sir. Otherwise or if it is non-decimal The rule is almost the same as the first non-rule. Zero must be found and then to the end. Last non-zero is not significant. Find it and then there too. Put brackets around the last non-zero Six is there too, put a bracket on this. How many people are inside the brackets? Two, three, four, five, six, that much There is only a significant figure and there is only a program. So if it is non-decimal, then it is not a decimal. First non-zero Last non-zero Only the people in between These two are significant. All you need to do is learn the rules, the rest is up to you. When we ask questions about rules Let's understand, then, the questions in the exam Without hesitation when asked You should be able to answer. For that, all these seven Questions and what is a three 10? I have questions for you now. You will be asked those 10 questions. Not even a question when you're done. There is no child you don't know. Okay, so Alan sir got it too? Did you answer each question one by one? First Answer: What is children first? Look, point zero. Decimal number is decimal number is first After the discovery of non-zero Everyone is significant but After that, there is only one person, sir, so answer that. How many one one's passed, next number? Decimal is the first non-zero decimal. So after the first non-zero Everyone is significant, everyone. It is significant how many children there are. There are four names, four significant ones. There are figures, one person, four people, decimal. Is the first non-zero and then all Significant is OK, next is here. Decimal is first, then everyone else. Find non-zero everyone It's significant, so how many people are there? Again, the first non-zero is four decimal places. Find out and then everyone Nothing significant can be imagined. This is not decimal, it is non-decimal. What is the rule if it is decimal, first nonce? Zero last non zero is him so The answer is that there is only one child. So if it's non-decimal, the rule changes. First non-zero Last non-zero Then Alan sir, you have said it correctly so far, Alan. Let's get rid of the sir for now. No, then by the way 1000 We will only give cash rewards if the name comes up. Okay, let's talk about 1000. If you don't come, no one will get anything. I'm not going to get anything, okay? I'm not going, what do you think? The decimal is the first non-zero number in the children. For non is significant until last Decimal is the first non zero, the last non Only three people are significant. The last question is decimal first. Non-zero and all after that The four things I've said so far are significant. I understood the answer to every question. I think that's great. No problem, if I tell you that rule. If you say "padapada" using the answer Okay, that's how it is. Different types of questions, children. Significant figures again You have to find five apples. I'm saying five apples, these five apples. When you say that, your children are one of them. What is the difference between five apples and five children? That's exactly five. Five means 501. No, it's five, what does this mean? If you say five, you can write it as 50, 500. Can be written as Even if you write 500, it is correct. That means five apples exactly. If I say the number, how many of those five? There is a significant figure, Infinite. Okay, but I'm five meters tall. If you say five meters or 5 cm, How many significant figures are there in one? There are significant figures, but five If you say apple, that's exactly right. If you say the number is five, then it is an apple. There is no doubt here, is that 51 Apple, sir? Where else can I apply? 10 They say things like "100 Students" The exam is exact numbers. Infinite when it comes to numbers The thing about having a signifier is Understand, next time, how much is 5000? There is a significant, but there is no simple. Is the decimal number the first non-zero? Last non-zero is a significant Sir, there is a figure of 5000 apples. If you say so, then it is an infinite signifier. Even if you say 5000 mangoes, it's infinite. The significator is 5000 people. It's not an exact number, it's half of it. There's still no point one. Infinite but just 5000 There is only one significant figure, if you say so. Okay, next, say 36*10 ^5. Children, isn't this power, power, power? Ortho Powers Significant When It Comes Figures zero is significant. No figures, no power. There is no significant figure, that's how it is. Just look at the 36 in the number to see the decimal. Is the first non-zero everyone? The answer is significant, how many two? There are only significant figures. Significant figures in power It won't happen, remember that. Thank you so much, actually. You should thank me. Because you get the cash prize. Thank you so much for leaving. I'm going to give you more work, children. Thousands of people have come here. Did you do this work too? Okay, this too. You How much is one cash prize each? It's not what everyone gets into. I have 20% more of that in my hand. I'm going to take it from you, that is, 100. If each person gets Rs. 100 No, since it's 1000, whatever. Everyone will get a minimum of Rs. 200. 200 20% 40 Rs 40 I will give you plus but for that What do you want, children, just for fun? But I need 1000 likes, okay, likes work. There is only a program that has been worked on. Okay, there's no program for the year. Ready, that's how we are next. Let's go to the topic Significant You have so many questions for Figures. Must be ready to do two marks There is a question about a mark, but There should be no doubt about it, okay? It's clear, that's how it is. Let's go to Next Dimensions Basic All dimensions of quantities I think you know. If you don't know anymore, hurry up and let's go. Let's learn what the dimension of length is. Write children as L in the box. What is the dimension of mass? Write in the box Next What is the dimension of time? Write in the box Write in the current What is the dimension of the current? Isn't the unit ampere, my children? Write ampere in the box. Or what can you do? I is another symbol for current. Let's write in the box, we need more amps. Okay, I'm going to use it. What is going to be used next? What is temperature, children? Can I write or not? I have time. No one knows what the unit of temperature is. Look, isn't it Kelvin? That's K. Write in the box Write K Write in the box, this is one in the exam. I'll ask Mark, did you hear that? Next What is the SI unit of luminous intensity? Don't you want to put your children in a candle? Its a simple CD. Write "CD" in the box. Who is next to raise children? What is the substance and its simple form? Write L or ML, what is the box? Write, the program is over, then seven. Dimensionality of Fundamental Quantities The formula should be learned as a basic. It's not enough to just study this, Alan sir. Okay, just say the answer and you're all set. If so, then next. Let's move on to the next question. More advanced questions The quantities advanced are What can you do with them? I need to be able to say the dimension formula all at once. So you've learned how to speed? Nothing is questioned here. Hey, sir, how's Speed doing? We are not going to discuss anymore. Study it, okay, if you know. If you know, you don't know, that's it. That's the thing, okay? I used to say, "Speed" Distance length is distance times time. It's time, it's not coming anymore. Now if we say speed, then lt ^ -1 Velocity and speed are the same. Velocity is both lt ^ -1 What is the difference when it comes to acceleration? -1 is not speed and velocity Acceleration will be -2 lt ^ -2 will be that much. There is a thing in the past, our one of this Alan Sir by Heart on Shot Live Alan Sir is teaching me hard. Did you see what the answer says? It's the examiner's. Sit down politely with me. If you learn, you can do it no matter how old you are. Anan sir, the thing about learning is that it is possible. What do you get from that live chat? I'm just explaining, okay, for the sake of etiquette. If you say force, just study. Nothing, this acceleration with M Katie. Stop with acceleration M L T ^ -2 If you add mass, it becomes force. The next thing is work or energy. Or even if torque work comes, energy Even if you say energy, it's kinetic. Let energy be potential energy. Whatever energy it may be, whatever energy it may be Even if work or energy comes, torque Even if it comes, it's nothing, this force's stuff. Write it down and write ml t ^ -2. Then replace L with L square. That's all there is to it, then work. Whether it's energy or torque Let's find the dimension formula ML square. If t ^ -2 is the next power, then the power Is there anything wrong with this work? Write t ^ -2 what to do -3 that's it Okay, so ML squared is t^-3 to the power That's all, so connect like this. Connect and learn. The next area will be easy, children. When you say length, there's only one L. If we say area, how many L will there be? There will be two L's or L square. How much is the volume? Dimensions are length width height. Everything is length, so how long is it? Yes, children, the cube is three lengths. That's all there is to it, sir. Density. In other words, mass by volume is mass by Volume Mass will lie on top of the volume If we say the volume is below, then L cubed. What does it mean when you say L cube is below? L race two minus three so you You should study it by heart or else Make your screen colorful. Take a shot and put it away. Only if you do it by heart We can move forward, okay? If it's not by heart now, then by evening. Make it overnight and make it. That's all, nothing more. There's no time to say it because it's based We have to deal with the problems that have arisen. Going but causing problems Before we go, let's take a look at the exam. Important question coming up, Alan sir. You also told me to move forward. What do you say, children? I have been here a long time. We are at the starting point, having said that. Starting with units and then The matter of significant figures Said supplementary SI units After we said the definitions and everything, We have completed significant figures. I have explained the basics of dimensions so far. Okay, isn't that right? If it's not difficult, let's Forward together for all It took 20 minutes to get this far. I have finished things. Okay, ready. The set is ready, okay, that's it. Let's ask in the next exam. A principle is a question that goes There is something called homogeneity. It's very simple, you ask. You know the children for example. Force is a quantity. If you say length, it is the same. Another quantity is a force. Can you add length to the number? Example: There is a force of three. Newton plus a length of 4 cm = Can I write seven? No, because what is the use of force against children? Length also has different dimensions. The force also has a dimension of mlt^-2. The dimension of length is just L, so With other dimensions I never know what quantities will do. Can't do add or subtract. A person who says this cannot be done The principle is the principle of Homogeneity, just read it now. Because you can write it in English. The Principle of Homogeneity must be followed. What does it say? That only quantities with the Same dimensional formula can be added or Subtracted with the same dimensional formula We only need quantities. Subtraction is possible. That's all there is to it, one K like. If you say you'll give me the money, I'll make it. Only something happens here. It won't work if you take a class and teach it. Isn't this what happens when you give a bribe like this? A question of what you will do. Should I bring it to the point where it's okay? It doesn't matter, let my money go. It doesn't matter. Didn't you do this many names? Ready, then this is it? This is just a mark for this. The principle of privacy is If you say "Omeganity", it's just a mark. Please answer the questions based on this. The following two types of questions are the main ones. Come up with a formula. I will give you this, you will say that. Is the formula dimensionally correct? You have to figure out what's wrong. How do we find out? Let's ask a question and see. A question that may come up on the exam Let's try it out, using the principle. Principle of Homogeneity Check the equation using this An equation is dimensionally correct if it is a Is the equation dimensionally correct or not? You should check whether it is simple. What should you do first? Write down the equation Half MV squared. = Even when written as mg In the three-mark question, you How many marks will you get? Children, half a mark. You'll get it right away, okay? Even though I don't know anything about it Write something down. Write down the item. This is your check. Okay, what to do, ready, now tell me, children. What you need to do in the next step Once you get an equation, the next step is You look at Equal to Plus Minus. People who were separated Look, there's no plus or minus here. So, get rid of it, but equal to Two separated by Aren't there people? One is this and one is that? They were both caught and put in a box. Put him in his box. Catch him and put him in his box. Sorry, don't be afraid, until the Onam exam. You can watch learning videos. If you can't, it's okay. After you finish your Onam exams, we will Live series start What will be done inside the batch? So you're live. You can study at that time. What can I do to prepare for this Onam exam? Just finish the lock, don't you hear? Okay, so it's learning video time. I will come to the table but you will wait for now. You are stressed to study. It's okay, you're live. We will go live after this Onam exam. The series begins with Agnibass inside it. Study hard, okay solution Don't get your children ready, don't come. Don't worry, relax. I'll make a way for everything, okay? Ready, children, two boxes, two people. You caught it and put it in a box. That's all these two have to prove. Is the dimension formula of the box the same? You must prove that or You should check this box. What is the dimensional formula for children? The box is V square, its dimensions are What is the formula Half's dimensional formula? What is half a quantity of children? No, it's a number, it has no dimension. The dimension formula for the next month is M. That is to say, velocity or speed. Dimension Formula Byheart We I have studied lt ^ -1 but not V. The square of is the square of so lt ^ -1. Don't forget to take it, sir. Take the square and let it lie outside. L has a square and this L has t ^ -1 Both of them deserve that square. Then square L and give ML. If we say square t ^ -1 squared 2*-1 is how much -2, isn't it? So t^- is over. This is the dimensional formula for this box. Did you get that? The dimensions of the first box. What is the formula, children? This is ML. Square T Whose Dimension Formula Is This? Look and tell me whose dimension formula is here. Haven't you seen it somewhere? Think about it and tell me where. I was thinking, listen, Next. The second one that said MGH Just look at the dimension formula. This is the same as the dimension of M. What is the formula for the dimension of Sir M? If we say that G is the same as the formula mass, Acceleration due to gravity is the children Acceleration due to gravity Acceleration due to elephant Let the acceleration be due to the ant. What is the acceleration dimensional formula L T? Isn't it race two minus two? That's why I wrote that. Okay, let's get the acceleration. If you say Next H, it's Height. If you say height, then length is So, all these people are in this combine. I did it, M is M is L is too All L squared has t^-2 and M. So we get L squared t^-2. The second box, MGH's I got the dimensional formula ML. Square T^-2 Now tell me the two boxes. Is the dimensional formula a match, sir? The match is ml² t^-2 ml² t^-2 The match is happening, so without further ado, We will write in the next step, children. Using children from the next step Using Principle of Homogeneity Full You should write it as it is, I am full. Using the principle of not writing Homogeneity What is wheat wheat? This equation is dimensional. I will write Dimensionally Correct DC You will write dimensionally correct using Principle We can say that this equation is Don't write "correct" dimensionally. Correct or not? We can't say this. Sometimes it will be correct, sometimes it will be May not be dimensionally correct. Is it correct? Is it dimensionally correct? We can say that then If you have a question like this, Can you do it? Can you do it? Let's see if we can do it again. You can ask questions by asking a single question. What else can we ask? Okay, let's get to the next question. Using dimensional analysis verify that Is equation F = dimensionally correct? You need to verify whether it is not What is the formula, children? The equation that says f=n m viva by t Yes, as soon as I write this, You will get marks, plus and minus. Isn't it just equal to two? Separated by equal to Catch people and put them in a box, including this one. They caught him too and put him in their own box. You put it in the box, okay? Ready, no problem now. You can use the dimensional formula for the box. Just look at each one and you'll see that it's F. The dimension formula of the said box is F. That being said, Force is the M of Force. We have learned that L T^-2. Now you have to learn by heart. It's clear that the children are the next second. Who is in the box mv / t is his We have noticed the dimensional formula. Let's see if M is the same as V. They have said velocity. We know that the velocity is lt ^ -1 Is divided by T is the same as T, okay? Now you be careful, be careful. Be careful, let M stay there. Let the L stand there and let this T be up. If we say t when it comes, then t ^1 is t When it comes up, t ^1 goes up. What happens when t ^ -1 is reached? So t ^ When he comes up t ^ -1 else t ^ It is already t ^ - t^-1, just add the power -1+ -1 -2 ml t ^ -2 is obtained first. mlt ^ -2 second of the box Does the ml of the box match t^-2? Sir, there is a match, so write it down. By using the principle of homogeneity We say that this equation is dimensional. Correct dimensionally correct understood I think it's a waste of time. Let's move on without doing the next question. Hold on, hold on, next question. Okay, let's change the next question. This is the equation, take the root of 2π. Is this dimensionally correct, M by G? Oh no, hurry up, hurry up, hurry up, this is all They will ask all this for the exam. I'll ask if this equation is one dimensional. Tell me quickly if it's correct, Dimensionally. Is it correct? Tell me quickly or quickly. This is what they ask in the exam. You must have studied sometime, sir. We know the formula, right? It's 2π*l/g, not m by g. If you say that and write it down It's not enough, you proved it. You have to prove it and show it. If you give it, some people will say dimension. It says it's correct. Why did you study? Formula You forgot to know that 2π*√l/g is Oh well, let's do it anyway. Let's see, all you have to do is equal to Separately, this The thing and then this thing Put it in the box. What is the first box? If you tell your children T is T, it's time. The period is one of the pendulum's Whose time is the time period of the pendulum? Whether it's a period or a time Whatever happens, it's time. What is the dimension formula of time? It's the same, alas, on the simple left side. Who is in the box on the right side of the tea bag? There are 2π children and then There is an M inside the root and a G below it. Okay, be careful, 2* pies too. What is the dimensional formula for children? They are numbers, not quantities. Is there no dimensional formula for numbers? Then I will ignore it next time. Who is inside the route? Who is on top inside the route? There is mass, okay, mass above. Dimensional formula for mass is mass m. If we say that G is the same, then the acceleration Due to gravity gravity No matter what, acceleration If the dimension formula is L T ^ -2 Okay, what do we do next? We do the route like this Putting this L and T Loading up, I'm all ready. It's on top, L says on top. When you hear l ^ -1, you say T. The one who climbs to the top comes to the top at t ^ -2 It will be a T square, just look at it. There's no need to simplify this further. Because you just look at it and say this. Will the two ever be the same? It will never be the same, that is, the left. The dimension formula for this box on the side is The dimension of that little thing on the right side The formula doesn't match either, then. Rewrite it using Principal Opportunity We Can Say That this equation is dimensionally wrong It doesn't have to be written as dimensionally wrong. It's okay to write "need" or "wrong". You can't write "Okay, correct." You can't write "dimensionally correct" But when you write "Rong", you Even if it's written as Dimensionally Wrong It's okay, just wrong. It's okay to write, but dimensionally Just write it as wrong, clear. Either that or it's dimensionally incorrect. It doesn't matter what you write. This is not a match on the left. The box and the box on the right The dimensional formula cannot be matched. This equation is dimensionally incorrect. Let me ask you a few more questions. A slightly more difficult question. Let's do this, children. Pay attention, pay attention. Pay attention, pay attention, v* t minus NT Cube Okay, this is an equation. Tell me quickly if it is dimensionally correct or not. No, sorry, I changed the formula to this: Chance to come will be = V T Minus AT squared this equation dimensionally Is it correct that Alan sir is gone? I think the children are in the next class, Alan sir. I think so. Some people must have left. Didn't you say Alan is spam? Alan Sir was told to get fired. There will be sadness, emotionally. It's too late to say. Alan Sir is an emotional man. You can't obey, you made me sad. Okay, didn't you make me sad? What should I do? Children, please pay attention here. Separated by two People are this and that minus this. They are separated people. This one too Did he also get three boxes? Got the box, three box dimensions. Look at the formula quickly, quickly, quickly. Look, first box first. If you say that the letter S is in the box, it is S. Who will be the first to see this equation? You have to understand that if you say S Displacement is motion in a straight line. Didn't you learn basic or not? Tell me or I will give it in the question. Don't worry, I'll say it in the question. They say the displacement is S. But if you don't say it, you should understand. If you say S, it means displacement. Isn't displacement a long word? Is it long or not? If we say V in length VT, If we say velocity T is time, Then take the second box. The V in VT stands for velocity. Velocity L T ^ -1 Tie T as If it says time, then write T. If you say "t", just say "t". If you say t ^1, then t ^ -1 t ^1 What happens if both are T's? Add powers one plus -1 zero t ^ zero is obtained as t ^ zero. One is basically l * 1. Only the one that comes is simply L. There will be nothing else but what will happen. That's basically it, okay, ready. Next, tell me, sir, do you want to take the minus again? No no no minus us The only thing in the formula is the box. Just take it and put it inside the box. If you say A is the only square Acceleration is acceleration, sir. We know that lt ^ -2 is the square of t. So it will be T square. Imagine if these two were there. When adding t ^ 2+ -2 2 - 2 is zero. So what will happen again in the end? I thought there would only be L. Look at the children of the three boxes. What is LLL of three boxes? The dimensional formula is the same for me. Let's write by using the principle of Homogeneity means that this equation Is it dimensionally correct? It actually is. Is it correct? Actually, it's not correct. What is the actual equation for children? S = U T plus half square is dimensional. This is also a limitation of the analysis. Let's have an equation that is actually correct. I can't say whether it is because actually This is correct. This is actually correct. No, but it is dimensionally correct. We can only say I understand that it's clear. I think we have dimensional To the next part of the analysis Let's go, that is, we have already learned. What is an equation dimensionally yet? You can tell whether it is correct or not. Okay, let's find that program. Or that program to prove You will learn it and ask it in the exam. The most frequently asked questions in exams It's a type question, nothing else. Chance to ask for something here too. There is, that is, the equation that derives Let's watch the program. Look at the question. If the kinetic energy depends on Mass and speed of a body arriving at It's an expression that means arrive at. If you say it's an expression, then its You have to make the equation yourself or It says you have to drive. How do you do this? Always keep your children safe. There will be quantity, who knows? That one who says it will depend Is there no quantity? You should take him first. Write down the kinetic energy KE. Write it as "K" or "K" It's okay to write "I am KE". This is written as kinetic energy. Who depends on the masses? Speed too, so you're next. Write proportional to the step. Write and then depend on who Write down everything they do. There is mass and there is speed, write it down. M * V but what power of M is it? I don't know if it's m ^1 or m ^2. I don't know, so that's M's. I gave the power a name. I don't know what power it is. So I gave it a B. Our Let's find the total work A and B. I'll ask about that drawback, you hear? I asked about limitations. I'll give it to you, I'll show it to you, did you hear the last one? I have a question. Okay, children, are you ready? What should I do next, sir? Change proportionality to equal to. Okay, I put equal to but equal to You have to be consistent when you put it in. We call the constant small k. Called in that constant dimension I heard it must be a constant that doesn't exist. Remember, okay, I'm going to race you. Equation What are we doing, children? I'm holding it in a box and then this Equation What We Do One This is called Equation One. This equation is called important. You have no problems yet. Okay, sir, I will teach in the fire department now. When we start the daily live class Most of the class in the record class My daily live class is mine. Even when we start, we are me, me I will be there to teach, okay? I'll run away from here. Okay, I'm ready. Now tell me. What should I do next, children? Equal to and separate here The dimension formula should be the same, sir. Check here, check your children here. No, what we are doing is the equation correct? The equation is correct now, not a check. Find that A and B. We are the ones who find it. What you do is what you should do. That's all there is to this box on the left side. The box on the left side is on the right side. You can find the box dimensional formula there. Take kinetic energy as an energy. What is the dimensional formula for energy? You should study by heart ml² t ^ -2 Kinetic energy as work done Let it be potential energy. Let it be everyone's torque. The dimensional formula is ml² t ^ -2 which is The dimension formula on the left side is now Write the dimensional formula on the right side. Does K have a dimensional formula or not? It is a dimensionless constant. What is the dimensional formula for mass, sir? Yes, but he has power. I forgot. Don't go, there's power, put it in the box. If you say V, it means speed. The dimension formula is L T ^ -1. There is power, don't forget to write power. Children also forget about the exam hall at the end. This power will just go like this That power will be written as M. Don't forget, okay, next time, kids. What are you doing out there? Look, there's an M Race A. No problem, is this Power B missing? Doesn't the power bone that says B have one? Write L is equal to B and T is equal to minus. What do you get if you power up One B? Nothing B into minus one then one If another power comes on top of the power, those two Multiply the powers by minus B. Multiplying by one gives minus B. So you get T-race to minus B. Okay, this is the left one. Sorry on the side, on the right side, on the left side. What is ML squared t^-2 now? Did you compare both sides? You guys compiled both sides. You will understand when you write, right? The power of A is here, the power of M is here. What is Sir One? It's not written there. That's one thing, so I can say that. I can say that A = A = 1. Okay, I got Simple M's Power Compair A. I took a second look and saw that L's power was B. Is L to the power of two, so I have What can be said is that b = 2. That's all, sir. I need to do something else too. The reason why you shouldn't do this is because the power of T is -b here. Here -2 is -b = -2 minus minus cut and get b = 2 again. We don't have any extra information. We only get A and B. The program is over, sir. What should we do? There is nothing more. Write Substituting in One. Substitute Write Tutting in Equation One. With Equation One Substitute it then. Kinetic energy is equal to something. Dimensionless constant in m ^ v ^ m If we say ^1 v ^2 then m^1 will be m v ^2 If we say v² then kinetic We have the formula for energy, children. K into MV square sir actually half MV is not square, yes, but dimensional. Using analysis, we can find that half It can't be made dimensional. This is also a limitation of the analysis. We will study in the limited time, okay then? KS Half if you want You can write it as "yes" but it's dimensional. When driving with analysis You should stop here. You are next. There is no need to go to the steppe. Is it clear? Do you understand? I think I understand. I think, okay, a question like this. Let's practice more. Only need to do What can you do? Only then can you write the exam with confidence. Okay, children. Okay, grab the children, but if the Time Period of a Simple Pendulum Depends on its length, mass and Acceleration Due to Gravity Arrives What is the expression at its? It says that every simple pendulum Whoever it is, it's not time. What does the time period depend on? It depends on what you are doing. Length Mass Acceleration Length Mass Acceleration Due To Gravity depends on these three people. What do we do then? We will write proportional to these three names. We don't know his powers. Power A, this power B, this power We will call it C, which we did earlier. Same step, no problem, okay? What will we do next? We don't like proportionality. I'll put equal to two there and see. But what do we do when we put equal to? Will have to wait for a constant K. Constant Katie L. Race said that To M race to B G race to C same Write again and that's it. Is this B in the box? Is this B? What do you do with this? In a beautiful box Put it in and then you Call this step Equation One. It's easy to learn just like this. Okay, now I can write the exam. You can find the dimensions of these two boxes. Think of the formula for this box and this You can use the dimensional formula of the box. Think about the time period on the left side. Is time period time the same as time? It's okay, it's simple. Equal to K dimensionless The constant is what we have been listening to. So there is no dimension, the next one is L. What is the dimension of L, sir? If you say that, they are long. I've said it before, blah blah blah. The dimension of the length of the blade is It's Formula L, but it's about power. Don't forget that there is a race to the L. Don't forget, it's an okay set. If you call your children the Next MM What should I read then? If you say M in the question, it means mass. It's not necessary to jump in, sometimes they're different. If you say something, M. They can say "moment" If you want, I'll tell you, then I'll take a look. You should look at the mass M in the question. In other words, mass is the mass dimension formula M. We know that M is the race to be. Don't forget, there's a B bed there. Acceleration if you say last G Due to gravity, they are already there. It has been said that acceleration is due to What is the acceleration of gravity? What is the dimension formula lt ^ -2 that lt ^ -What is the power of G? You have to give a total of C for ^ -2. Okay, what are you doing all this for, sir? What you need to do is give the children a little something here. There is a problem, M M Race to B, another M Nothing but L looking at L race to There is a L l ^ C lying there. So we have to bring them all together. There are multiple people in that You are multiple people. You can only unite if you It's possible to compile, so how is that? Do it, there is no one else for me, so I ^ If you just write B first, M will be race B. There is no one else. Next l ^ is there, okay? Let it stand there and then this Open the bracket and LNC We get then l ^ c then c at t ^ -2 We get t ^ -2 * c or t ^ -2c Now you combine two bones. How to combine m ^ b There will be l ^ two powers added together. There will be plus c then t ^ -2c This will be the dimension on the right side. Formula M, L, and T are separate. I got it now you are the composer. Sir, how do you compile it here? How much power do you have? How much power do you have? What is the power of M there, sir? There is no M there, only T. Meaning, how many powers of M are zero? So M's power is zero, M's power is B. That is, the power of M is zero. = How many zeros past B? Children are zero, next is here. Let's leave the plus C there, let's have C. There is only one person in Time, after all. There are A and C, but they are not needed here. Let's hold this -2c is T's Power here is T's power what is nothing Didn't you write it or didn't you write anything? If you say there is one, then -2c What will be the children -2c = 1? That is C = How do you get C = If you take -2 and add it, you get -1/2. So what is C, children -1/2 what is b? Children, I got both of these. I think you are the last one. The length is A plus C. What is here, sir? There is no length here. That is, zero is the power of length, so A. Plus C = zero, you get C already knows then Substituted C If we say -1/2 then a - 1/2 = zero -1/2 Going beyond it will be +1/2 so A = Did you get just 1/2 or +1/2 ABC? Hold it and write it down. Substituting into equation number After substituting one The program is over, that's all. The rest of the event is up to you to decorate. What is the program to write for? What if you substitute? The dimensionless constant that says There are l ^ l ^ to a is l ^ how much is half Is that the race to the next half? Race to B is B, how much is zero sir? So the power of mass is zero. It does not depend on whether m ^ zero. If I say one, my race is zero one. Okay If you say next c g ^ g ^c -1/2 is so g ^ -1/2 is next We will write in step t = k * l ^ half m ^ Zero n ^ zero is one, so don't write it. No need, one is enough g ^ -1/2 okay g ^ -1/2 is what I heard in the last step. It is written because the power of g is c. If you say C, it's -1/2, okay now. Write in the next step, children k * l If we say ^1/2 g ^ -1/2, what is 1/g? ^1/2 is what will take it down. That's all minus power to show minus What does it mean to hit? Just take it down and that's it. Done, so g ^ -1/2 down. When going back to g ^ -1/2 Didn't you write that Plus One is 1/2 and now Race Two? What is this race two if you say one 1/2? What does it mean when you say one 1/2, children? Basically, it means root. What is this? What is this? What is this? What is this? One by one route L is the bottom G race one by one Okay, so this route is called Route G. I think it's common. Since both of them have root, * The root of L by G is the time dimension The formula program is over. Now if you look at the actual equation You will understand the time period. We will learn about the equation oscillations. Your last second, if you say so. This is the equation we will study in the chapter. Then you will understand this K. You will understand what the value is 2π. But that's this dimensional formula You can use it to create dimensional What do you get from using the method? You can't do it. If you can't find it, then you Don't stop here. Ready, ready, I understand. I think I have one more question for you children. What if you do it there? Even if it comes To gain the confidence to do 100% Just one more question for you. What if Did you say? Hold on to the centripetal force. F depends on centripetal force What is that, sir? You need to think about the force. Isn't that force dependent? What are they doing? Should I write proportional? Proportional? Write it down, now tell me what it depends on. What you do depends on the mass. Are you doing it? Have you started writing? Velocity Velocity Depend Start writing down what you are doing. Radius, which depends on Radius, is a Whose radius do you need to look at? Let the radius of the circle be Let radius be the radius of the sphere. We need radius, whose radius? It's not relevant here. While studying other chapters, there The relevant matter is the relevant matter here. No one's radius, radius power, sir. I don't know, give me the power, A. Our job is to find BC. Proportionality in the next step Which question is the demand seme program? Even if you come, you shouldn't do the same program. Proportional demand equals demand. Let k be a dimensional constant m ^ b. ^ b r ^c Okay, now what do you do with this? Grab it and put it in a box, it's Equation One. Call it the same program yet. The same program that was done is called Equation One. Call because we have to write in the end. Substituting in Equation One This is what you should write. Dimension of Force Formula per Dimension Write down the dimension formula of force M. We know that L T ^ -2 = K is the dimension of K. There is no formula, the mass is M ^ If you say V, it means velocity. I know sir lt ^ -1 is lt ^ -1 but You must not forget its power. Power should be provided as common. L should be given outside the bracket. Don't give it to me in vain. Who should be given the total number? If we say that radius is radius, If you say, what is the length, is it not length? What is the length of a race? To C is the problem again because L is here There are two L there so we have Open the brackets and press L. I need to put it together so I can do it. I have another one. No one is in this bracket. If you open it, you will get LNB, so B l ^ b will get t ^ -1 b will get t ^ - B There is L Race C For all this If you combine with me, I will get M race to A, my children L There is Race to B and Race to C. What would that be, Race to Powers? Add B plus C then T race. Two minus B, isn't that all there is to it? Now you are left side and right side. You Equate Powers program Solve here Power M's Power A here How much power does M have, sir? There is nothing. Here one means MA, if there is no power It's called zero but M has power. If it is not written, it means power one. That's a first for me. It can be said that A = 1 person. You got it, now you jump and grab the power of L. To equate Before you think, here is a B plus. C is then B plus C = what is there? We don't care if we get it. What's better than that? The power of T. There is only one person with minus B, the power of T. There is -2 so it will equal Children -b = -2 - b = -2 minus and minus If you cut it and throw it away, you will get What is the value of b to the power of b = 2 b? Got 2, got last one, you got it. Look This is the power of B plus C = L here. Nothing means one, then. That B plus C = 1 We know that the value of B is two by writing So write two plus c = 1 and write c = 2. If you go there, it's one minus two or minus One is What's the next program? Substituting this into Equation One Write as can be substituted. Just take it and that's all there is to it. Just substitute. Program F = There is a K, so what? Substitute each of M's. What is the power of A? So what is one of M? Power One is what I need to write about. If you say "M is needed, power one" Just write M Race to One or M. The power of OK Next V is B. If you say that, then the power of the word "Apo" is two. Two is the last word of V Square. Power is not R's power, but C's power. So you say minus one, so you're race to -1. Okay, think about it again. If we say that K * MV squared r ^ -1 What is -1 +1 when brought down? It will be that simple. This is the formula for centripetal force in What is the actual value of K? But we can't get that here. That's all you need to do here so far, it's clear. Are the children clear? Are the children clear? If you ask your children one question, Chapter finished, to ask for exam The question is going to be written down by the children. At these two limitations of dimension If you ask for two analyses, you get three. Write it down, that's our way. This method is the value of We calculated the constant B Didn't you do this dimensionless constant? Can the value be calculated? It can't be in any formula. Can you calculate it? So the dimensionless constant We can calculate the value using this method. That's the first thing that can't be done. Limitation Second Limitation Before Can you read the third limitation? Check only weather an equation is Dimensionally correct or not. Can't Tell Weather the Relationship Is Actually Correct is an equation actually correct. Can he tell me if it is or not? Just wondering if it's dimensionally correct. Is the dimension correct? It can only be said that This guy really thinks it's the correct equation. We can't tell you in advance. I had seen it, right? s= vt - at Not a square correct equation but I can tell you that it is dimensionally correct. So to say whether it is correct or not? Is it dimensionally correct or not? This is all I can say. The second limitation is another one. There are limitations, let's read them. This method equation containing Trigonometric Exponential Logarithmic terms cannot be analyzed. That is, sine theta is like cos theta. People People like Log X If we say exponential, then e ^ x People like these have no dimension. Because there is no such thing as such. You can analyze equations with terms. It can't be done, it's optional. Just write it down, at least you will get this one. Point and this one point you It's clear, just write it down. These are the things that ruin children. You should study and take the exam. Let's go, sir. Why do we need to study anymore? It seems like what are we doing? Will you still practice the question? I think we should do it then. What will you do, children? Anything else? There's only one thing you need to do. You only need to do this chapter now. You take the app Previous Year Question from the previous year in this chapter My own video of the questions There are solutions out there, what can I do about it? I have done this to my children.
