Question

What are the effects of a force acting on an object?

Answer 1

1. A body can be moved by a force. For example, pushing a ball that is at rest on the ground causes it to roll. 
2. A moving body can be stopped by a force. For example, applying the brakes can stop a moving bicycle. 
3. A body's speed can be changed by a force operating on it. For example, the friction between the brake shoes and the tyre rim causes a bicycle to slow down when the brakes are engaged. 
4. The body's direction of motion can be changed by a force. For example, when a body moves in a uniform circle, the force exerted causes the body's direction of motion to constantly change. 
5. A force has the ability to alter both the body's speed and direction of motion. For example, both the ball's speed and direction of motion alter when a bowler's ball is struck by a batsman. 
6. A force has the ability to alter the size and form of the body it works upon. For example, when a rubber ball is compressed, it deforms and loses its spherical shape. Its volume may also drop.
