State the effect produced by a force in the following cases :

(a) The sling of a rubber catapult is stretched

(b) A man pushes a heavy cart

(c) A player uses his stick to deflect the ball

(d) A cyclist applies brakes

(e) A spring is compressed.

(a) The sling of a rubber catapult is stretched → changes the shape of the sling and increases it's length.

(b) A man pushes a heavy cart → changes the state of motion so cart starts moving or speeds up.

(c) A player uses his stick to deflect the ball → changes direction of motion of the ball.

(d) A cyclist applies brakes → the speed of the cycle slows down and may come to rest.

(e) A spring is compressed → shape changes and length of the spring decreases.
