 Hello everyone. Today with the help of a simple demonstration with basket ball and tennis ball we will see that how transfer of momentum takes place. So for that let's see that what is happening now. If we drop a basket ball from this height you see the height it bounces back. Similarly if I place these two balls together and drop it from the same height we will see the how it bounces back. Now tennis ball over the basket ball and see what happens when you are dropping it from the same height. Can you observe the difference in height previous and now. So now while it happens let's see. We have already discussed like Newton's laws of motion in that we have studied a term called momentum. Momentum is actually the measure of motion which depends upon mass and the velocity. In physics we say P equals to mass multiplied by velocity and P is the momentum over time. Now the experiment on demonstration I have shown you right now. You can see the difference in the height of a ball when that tennis ball is sketched over the basket ball. In the first case shall I show you again. In the first case you see the height of the ball it bounces back. This is the height it is because the transfer of momentum takes place from basket ball into the tennis ball. Since the mass of the tennis ball is small velocity is high and therefore it goes to a higher height. So I hope you will understand the power transfer of momentum takes place. Thank you for watching this.
