Question

Why does a gun recoil when a bullet is fired? Calculate the velocity of recoil of the gun.
Or
When the bullet is fired from a gun, the gun gives a kick in the backward direction. Explain why?

Answer 1

Answer:

In this question,

When the bullet is fired from a gun, the gun gives a kick in the backward direction due to conservation of linear momentum i.e the backward recoiling of the momentum of the gun balances the forward momentum of the bullet to maintain net-zero momentum. As the mass of the bullet is small its velocity is very large, while the mass of the gun is large so its velocity is small in the opposite direction to the bullet results in recoiling.

Answer 2

HEYA MATE HERE U GO.

❤. This is due to the 'law of conservation of momentum ' .

❤. When a Bullet is fired from a gun , the momentum to the Gun becomes equal and opposite to that of Bullet.

❤. So , When the Bullet moves forward , the Gun kicks back.

❤. This motion of Gun is called Recoil of the Gun.
