3. A force can change the direction of a moving object. Explain this statement with an
example.
Answers
As the rocket burns fuel, it loses mass. As the mass continu- ally decreases, the acceleration continually increases. Forces can change the direction of motion. ... For example, a good soccer player can control the motion of a soccer ball by applying a force that changes the ball's direction but not its speed

Explanation:
1) A force can move a stationary object
Example : The force of motor makes a stationery fan to move ( rotate).
2) A force can change the speed of a moving object.
Example : When a hockey player hits a moving ball, the speed of ball increases.
3) A force can stop a moving object.
Example : The force of brakes can stop a moving car.
4) A force can change the direction of a moving object.
Example : In a cricket match, when a moving cricket ball is hit by a bat ,then the direction cricket ball changes.
5) A force can change the shape of an object.
Example : When force is applied on flour dough, it changes it's shape .
