Interpretation:
The situation which illustrates potential energy changing to kinetic energy is to be described.
Concept introduction:
Potential energy: It is the energy which is stored in a body. It is due to its position.
Kinetic energy: It is the energy that is due to motion of a body.

Answer to Problem 55A
Example: A ball dropped from roof towards the ground involves conversion of potential energy into kinetic energy.
Explanation of Solution
The ball at roof has potential energy stored in it due to its specific height. When this ball is dropped from the roof top, it moves downward due to pull of gravity. In this process, potential energy is converting into kinetic energy.
There can be many processes which involve conversion of potential energy into kinetic energy.
