What are the effects of a force acting on an object ?
(Note : a body `-=` an object)

Explanation

(i) A force can set a body in motion. For example, if a ball at rest on the floor is pushed, it rolls on the floor. (ii) A force can stop a moving body. For example, a moving bicycle can be brought to rest by application of brakes. (iii) A force acting on a body can change the speed of the body. For example, when brakes are applied to a moving bicycle, its speed decreases due to the fricition between the brake shoes and the rim of the tyre. (iv) A force can change the direction of motion of the body. For example, in uniform circular motion of a body, the direction of motion of the body keeps on changing due to the applied force. (v) A force can can change the speed as well as the direction of motion of the body. For example, when a ball bowled by a bowler is hit by a batsman, there occurs a change in the speed as well as the direction of motion of the ball. (vi) A force can change the change the shape and size of the body on which it acts. For example, when a rubber ball is pressed, it gets deformed and hence no longer remains spherical. Also, there can be a decreases in its volume.
