Question

(a) On what factors does the gravitational potential energy of a body depend?
(b) Give one example each of a body possessing : (i) kinetic energy, and (ii) potential energy.

Answer 1

(a) Gravitational potential energy of a body depends on its position above the ground.
Example - A book kept on a table possesses gravitational potential energy because of its position above the ground.

(b) (i) Kinetic energy - A car moving with some speed on a road possesses kinetic energy.
(ii) Potential energy- A stretched rubber band possesses potential energy due to the change in its configuration.
