Question

Can I say that energy possessed by a body is the measure of the work done on it?​

Answer 1

Answer:

Energy can be defined as the capacity to do work.

Let us take an example, for our better understanding. A stone cutter raises his hammer

vertically above the stone and then hits it to break into small pieces. In doing so, he

does some work in raising the hammer. If the hammer is allowed to fall on the stone, it

can do work in breaking the stone.

Thus, the work done in raising the hammer has been stored up in it, giving it the ability

of doing work. Now, when the hammer is resting on the stone, it can no longer do any

work. Thus, we can say that the raised hammer has the energy or ability to do work. The amount of energy possessed by a body is equal to the amount of work it can do when its energy is released
