Answer
The examples are as follows —
(a) Stops a moving body — A fielder on the ground stops a moving ball by applying force with his hands.
(b) Moves a stationary body — A ball lying on the ground moves when it is kicked.
(c) Changes the size of a body — By loading a spring hanging from a rigid support, the length of the spring increases.
(d) Changes the shape of a body — On pressing a piece of rubber, it's shape changes.
