Kinetic energy, when we are referring to kinetic energy, it is the energy possessed by a body by virtue of its motion.
00:09
So we can define it as energy of a body or possessed by a body by virtue of its motion.
00:25
So when a body is in motion, it is going to have kinetic energy.
00:29
So there are various forms of kinetic energy.
00:32
In terms of mass and speed, we write it as half m b squared.
00:36
In terms of momentum, we can write it as kinetic energy is equal to half time p squared divided by m, where p is the momentum of the given body.
00:48
Now according to the question, they have given us the mass of the body, which is 0 .5 kg, and the velocity of the body is 10 meter per second.
01:00
So we can either use the first formula or the second formula because momentum can be defined as mass in velocity and we can find out the kinetic energy.
01:08
Therefore kinetic energy in this case is going to be half times mass which is 2 .5 times square of velocity or the speed which is 100.
01:19
So from this we are going to get 100 divided by 4 with this 25 june...
