Hello everyone in this question.
00:03
We are going to find the kinetic energy of a ball of mass and the mass of the ball is 200 gram and it falls from a height, height which we can abbreviate as h equal to 5 meter.
00:20
So we have to find the kinetic energy of this ball when it reaches the ground.
00:26
So to find kinetic energy of this ball.
00:27
So to find kinetic energy of this ball.
00:33
So to find kinetic energy of this ball, ball when it reaches the ground.
00:46
Okay.
00:47
Now here we cannot simply find the kinetic energy.
00:50
We have to use a relation which is as follows.
00:53
Kinetic energy, kinetic energy for a body at the lowest point will be equal to potential energy at the highest point.
01:21
All right? let me explain it to you pictorially.
01:24
For example, if a ball was thrown like this, okay? so at this height, the maximum potential energy that we obtain will be equal to the kinetic energy when it is at the lowest point...
