Answer 2

Answer:

1. a force can set a body in a motion for example if a ball at rest on the floor is pushed ,it rolls on the floor.
2. a force can stop a moving body for example a moving bicycle can be brought to rest by application of brakes.
3. 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 to the friction between the brake shoes and the rime of the tyre.
4. 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.
5. a force 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.
6. a force can 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.
