Recoil (often called knockback, kickback or simply kick) is the backward momentum of a gun when it is discharged. In technical terms, the recoil caused by the gun exactly balances the forward momentum of the projectile and exhaust gasses (ejecta), according to Newton's third law. In most small arms, the momentum is transferred to the ground through the body of the shooter; while in heavier guns such as mounted machine guns or cannons, the momentum is transferred to the ground through its mount. In order to bring the gun to a halt, a forward counter-recoil force must be applied to the gun over a period of time. Generally, the counter-recoil force is smaller than the recoil force, and is applied over a time period that is longer than the time that the recoil force is being applied (i.e. the time during which the ejecta are still in the barrel of the gun). This imbalance of forces causes the gun to move backward until it is motionless.
A change in momentum results in a force, which according to Newton's second law is equal to the time derivative of the momentum of the gun. The momentum is equal to the mass of the gun multiplied by its velocity. This backward momentum is equal in magnitude, by the law of conservation of momentum, to the forward momentum of the ejecta (projectile(s), wad, propellant gases, etc...) from the gun. If the mass and velocity of the ejecta are known, it is possible to calculate a gun’s momentum and thus the energy. In practice, it is often simpler to derive the gun’s energy directly with a reading from a ballistic pendulum or ballistic chronograph.

Plot: Volta Hudson (Brandon Scales) was Don Mars's (Harrison Ornealas) best hitman. When he retires, Mars sends the a gang of assassins, lead by Jimmy Middleman (Anthony Occhipinti), to destroy Volta and his loved ones. However, Volta fights back, and takes on hit squad after hit squad in order to rescue the woman he loves.
Genres: Action, Short,Five thousand years, that's a lotta tears
and your world's still crumblin' down
So full of hate, you've sealed your fate
and your world's still crumblin' down
So many scars after all the wars and wars and wars
and your world's still crumblin' down
Your battle cry echoes as you die
and your world's still crumblin' down
The rockets fly across the sky
and your world's still crumblin' down
You take and take, for heaven's sake
and your world's still crumblin' down
You only feel the pain you deal and deal and deal
and your world's still crumblin' down
Peace can't be known, that dove has flown
