When a gun is firedwhy it recoils?
Newton's Law- for every action, there is an equal and opposite
reaction. When the bullet is pushed forward out of the barrel, then
the gun is pushed back by an equal amount. That is recoil, or
"kick". The amount is based on the weight and speed of the bullet,
and the weight of the gun. All things being equal, a light bullet
kicks less than a heavy bullet, and a heavy gun kicks less than a
lighweight gun.
