उत्तर
A force can produce the following three effects:
(i) It can bring changes in dimensions. For example, in stretching a spring its length increases.
(ii) It can start or stop motion. For example, a ball moves when kicked.
(iii) It can change the speed or direction of motion. For example, a hockey player changes the speed and direction of the motion of the ball by his stick.
