1. What are force and its effects?

A push or a pull on anybody is called Force. The direction in which a body is pushed or pulled is called the direction of the force. For example, if a horse cart is pulled by a horse in the east direction then that â€˜pullâ€™ is the force and east is the direction of the force.

Effects of Force

We cannot see the force but through its effect, we can identify the force. There are various effects of force as explained below-

• Making a stationary body move. For example, Kicking a ball at rest.Â

• A force can stop a moving body. For example, Brakes applied on a moving cycle.Â Â

2. What are the 3 Laws of Motion?

Newton gave the 3 laws of motion that describe the motion of moving bodies.Â

• First Law of motion:- A body at rest will remain at rest, and a body in motion will continue in motion with uniform speed unless an external force is applied on the body to change its state of rest or uniform motion.

• Second Law of motion:-Â  The rate of change of momentum is directly proportional to the applied force, and takes place in the direction in which the force acts.Â

• Third Law of motion: To every action, there is an equal and opposite reaction. Example: Firing of Gun.
