once very rightly said, live your life with an exclamation, not an explanation. Greetings everyone, this is Amanat and this is Aileen and we are here today to explain the Newton's laws of motion with an exclamation. Amanat, Amanat, you will not believe what I went through yesterday. Well, not until you tell me. Well, obviously. Okay, so remember how I went to Allahabad last weekend? Ah, Allahabad. That does ring a bell. Oh yeah, I remember you blabbering something about it. Okay, yeah, so me blabbering. Okay, it was a really nice trip.  And we thought of ending our trip with a completely new experience of river rafting. Oh, I love river rafting. I love river rafting too. But well, until I was getting off my boat and the land literally whooshed from under my feet. Well, you mean as you were trying to get to the shore, the boat slipped away as you fell down. My friend, that is one very scientific way to describe my fault. But alright, we'll take it. I would like to call it just a better way to explain your situation. Sure. Well, yeah, girl, I know I am better. Okay. Anyways, have you brought the topic of science up? I really want to explain the theory behind your fault. Oh, Amanat Amanat. We all know that I hate science and you very well know that. Don't do this to me. Oh, girl, I know you hate science. But apparently I am a great teacher. Try me. Okay, we all know here yet again that I will not end up loving science after your theories. But alright, give it a shot.  So the situation you were in illustrates Newton's third law of motion. And I've never heard of that. Okay. Well, I sort of did not expect more from you. So anyways, keep your ears open. And so do you. Newton's third law of motion states, every action has an equal and opposite reaction. And with that theory, I might have heard of that.  Oh, that's great. Well, apparently you should have known it because you're in ninth grade. Do you not pay attention to Amit Sir's physics classes? About that. That is one very controversial topic to be talking about. Not gonna lie. Yeah. Well, girl, you told the wrong person. I shall surely convey this to him. Amanat Amanat. You're not that bad of a person. Well, I know I'm not that bad.  Okay, I do not need this to reach him. So alright, you went.  So when you were trying to reach the shore, you applied a force on the board. And this was the action. The board hence applied the same force on you with an equal magnitude in the opposite direction. And this was the reaction. And as the board is on the water and it's not stagnate, it slipped away as you fell down and the land whooshed away. Okay, with that theory, that does kind of make sense. Alright, that is interesting. See, I told you physics is amazing. Alright, sure. But okay, why doesn't this also apply to me jumping off a train? Well, that is also me jumping off of it. Why does that also not displace? Wow. Well, I must say, girl, that's a great question. I'm a good student. Yeah. Newton's whole train. That's Ringabella. You know what? I feel like Newton was a little dumb. He thought about the board, but he forgot about the train.  Your law of motion also applies and you are displacing from the train. But as stated in the total law of motion, there's also a second law of motion. Change of rate of moment. Or in simple language, shall I say, force is equal to mass of the product and actuation of a body. The mass of your body is known in front of the mass of the rain. And henceforth, train does apply and equal an opposite reaction to your first, but due to the difference in mass, it isn't reasonable. And next time, my child did not doubt Newton. Okay, he sure did get offended on that. All right? Yes. So anyways, as Newton very rightly said that F is a force is directly proportional to the change in momentum upon time. And as we can write, are you seriously thinking I understand all of this? Oh yeah. I'm so sorry. I forgot.  Okay, wait. Yeah. The iconic scene of DDLG. Okay, show me the video. Show me the video. Why not? That movie just brings so many memories back. I used to run along with when I was younger. Okay. Well, talking about running, doesn't Newton's third law of motion also apply to walking and running? Oh, I never thought of that. Well, if you think of it when you are walking, your foot is applying some amount of force on the ground, which will come exactly opposite to your feet and you will walk. Is that right? Oh, yeah. And when you're running, the force will be at a higher magnitude and a higher force. That's why your force will the pace will increase, right? Yes. And that's why we are able to run. And while running, our speed is more than when we are working. Exactly. Oh my God. I really cannot describe my felicity right now. I shall charge for these amazing classes. Okay, before being that confident about your teachings, because give me another example.    There? Yeah. Why not? I'm very sure about it. Okay. Go on. Nice and hard. Let's go. Oh, wait. That's an earthquake. Wait. Oh, damn. Okay, that was ready. Oh, no. Yeah, things are falling off. And okay, that was a very huge one. Yeah. Why do earthquakes happen in the first place? It's annoying at times. Oh, wait. Earthquake. Does that ring a bell? No, no, no, no. Amanat, Newton cannot be everywhere. Apparently, Newton is everywhere. Now this is simply annoying. But okay, go on. Yeah, I have to explain it to you. So, well, can you tell our audience that why does earthquake take place? Because of the movement of the seven big, big tectonic plates? Yes. You do know something. Okay. So, the earth is divided into seven big pieces of land as we call it the tectonic plates. And due to the movement of the tectonic plates, this causes earthquake, tsunamis, volcanoes, etc. Well, when one tectonic plate is in contact with the other tectonic plate, it releases some amount of force on the second tectonic plate. And as a reaction, the second tectonic plate also applies the same force in an equal magnitude in the opposite direction of the first tectonic plate.  Well, there are several parts to it. Tectonic plates are of two types, convergent and divergent. Do you really have to tell me that? I know all of this. Yes. Let me come through. I pay attention in geography classes. All right, I'm just not good at physics. Okay, one thing, one thing, just one thing, please. So, as we know that Newton's third law states every action has an equal and opposite reaction. So, equal reaction causes strenches, whereas opposite reaction causes mountain formations. Is that it? Yeah. Okay. Well, okay. Wait, wait. Won't we be talking about something else before? Exactly. Oh, right. Punching walls. I'm just very good at punching. Punch this wall right here. You won't lack a topic. Nope. Nice and hard. Here we go. Oh, my God, that hurts. Obviously, it hurts. And you know why it hurts? Why? Oh, dummy, because of the amount of force that you apply with your hand on the wall, it's going to come back with the equal and opposite force on your hand. It's going to hurt. Right. Newton's third law motion. Okay, but could you not think of any other example in this world instead of trying to break my hand? Okay. It's just how I teach my friend. Just get used to it. Okay, I guess I have to. Okay. But does Newton's third law motion apply to anything else but these normal examples? Sports? Of course. Sports. Yes. You know what? There are several sports that work on just the phenomena of third law of motion. Examples. Take Javelin throw or pole vault, spring board, diving, swinging, swimming, running. Okay. With the, what did you just say? Javelin throw. Javelin throw. Right. I have a video. Why don't you just go ahead and play it? Sure. I guess that will explain the third law of motion very easily. Come on, India. India. Whoa. Go, India. And that was a clip of me and Chopra winning a gold medal for India. He's the best after all. Of course. Well, okay. So did you understand the physics behind it? Oh, I did. And doesn't the same also apply to pole vault? Yeah. Explanation. Yeah. Okay. I will give it a go. Don't mind me stuttering because it's my first time. Okay. So a pole vault has a pole in his hand. Obviously that's the entire sport. Okay. When he's running with the pole in his hand, he will, what will he do? He will apply. Yeah. He will apply force on the ground with the pole. It's my explanation. Yeah. Okay. He will apply downward force on the pole, which will propel him up in the air, right? Yes. Okay. And that will cause him to yet again fall down and the amount of force that he applied on earth will strike back on to him. Wow. You're a great student. Just amazing. Yeah. Okay. Well, while you were trying to explain the pole vault, I just remembered that I have another example for you. Okay. We've had a lot of examples today. It's too much knowledge. Let this be the last one. Well, do you see this balloon? Did you magically just reappear it from your folder? We don't talk about that. Okay. Anyways. So do you want me to turn this balloon again into magic? Oh, I love magic. I don't see the behind the scenes. Just give me a sec. Let me just blow it away. So, what do you think would happen if I just leave this balloon right now? It will fly away like a rocket. Yes. And why would that happen? Newton's The Love Motion. Oh well. That's magic. That's mastermind. That's how you teach. Okay. I am definitely passing and topping physics this year. Thank you.


Hi everyone, my name is Purnmani N. I have secured All India Rank 540 in UPSC's civil service examination 2018. I was born and brought up in Chennai and I finished my college in NIT Trichy. I started my civil service preparation from my last year in college which was mostly self-preparation. Later I moved on to Chennai and I joined Shankar IA's academy for my prelims, main and interview guidance program. My optional was sociology and Rajda Ma'am was a wonderful, it was a wonderful experience having her as my mentor for sociology. She helped me in all the steps and all the phases of the examination process and Shankar IA's academy helped me in knowing the process a bit more and molding me and making more better of myself in the whole process. I am thankful for Shankar Sir and Vaishnavi Ma'am for helping me get here and also to my parents. Thank you.
