Question

When a bullet is fired from a gun, the total momentum is constant ?​

Answer 1

Answer:

So the momentum of the bullet plus gun should be conserved. Conservation of momentum is the law that is held true when the gun is fired and a "kick" is felt. When a bullet is fired from a gun, total momentum before is zero since nothing is moving. After firing the bullet there is a momentum in the forward direction.
