Give the scientific reasons for the following.
(b) Why is a person thrown backward when, he fire the bullet from a gun?
Answers
Explanation:
Because according to Newton's third law of motion, every action has an equal and opposite reaction. So when a bullet is fired a force is applied on the bullet to move forward with a great speed. So as per the third law of motion, the bullet applies a similar force opposite to it's direction that is to the gun. That's why the person holding the gun is pushed backwards.
Explanation:
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.
When a bullet is fired from a gun, the gun exerts a force on the bullet in the forward direction. This is the action force. The bullet also exerts an equal force on the gun in the backward direction. This is the reaction force. Due to the large mass of the gun it moves only a little distance backward by giving a repulsion force at the shoulder of the gunman. The backward movement of the gun is called the recoil of the gun.
Thus, Newton’s Third Law of Motion describes the relationship between the forces of interaction between two object, as it says every action has an equal and opposite reaction.
Action = –Reaction
