Newton’s third law- Every action there is equal to an opposite reaction. Whenever two bodies interact with each other, the force exerted by the first body on the second is called action. The force exerted by the second body on the first body is called reaction. The action and reaction are equal and opposite.
Examples of Third Law of Motion
- When a ball hit the ground or a wall the ball apply a force on the wall or on the ground. The wall or the ground apply a reaction force then the ball bounce back.
- When a bullet is fired from a gun, the gun exerts a force on the bullet in the forward direction.The bullet also exerts an equal force on the gun in the backward direction.
- A person is moving forward during swimming
