Answer: (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.
