Question

state the law of consercation of momentum, why gun recoils when fired​

Answer 1

Answer:

The conservation of momentum states that, within some problem domain, the amount of momentum remains constant; momentum is neither created nor destroyed, but only changed through the action of forces as described by Newton's laws of motion.

The gun recoils when fire Because there is no external force on the gun-bullet system, it would conserve momentum. If the bullet gain momentum in one direction, the gun would gain momentum in the opposite direction.
