In the case of a semi-automatic pistol, expanding gases push everything in the barrel apart, propelling the bullet forward down the barrel, and the slide back toward the user. The slide continues its momentum back until it cannot go any further (At this point, it begins chambering the next round), the slide is transferring it's kinetic energy into the frame of the gun. The gun pushes back into the hand, and the hand torques back and up, experiencing "kick". In the case of limp-wristing (not holding it properly/tightly enough), or powerful magnum rounds, when the hand cannot torque anymore, the momentum will force the elbow or shoulder to bend, creating that infamous sight of a huge gun flying upwards after being shot. Any excess energy at this point has been absorbed by your body (or if the recoil was extreme, forced the user to step back to avoid falling). Finally a spring pushes the slide forward, sending the gun back (Though very small compared to the actual shot, it's noticeable.)
Bullets are very small but move at incredible speeds, rendering them lethal.
Conservation of momentum - The momentum (m*v) of the small object (bullet) is equal to the momentum of the gun recoil.
Kinetic Energy - The kinetic energy (1/2 m*v*v) of the small object (bullet) is about 350 times as much as the energy of the gun recoil. About 99.7% of the gun powder energy is used to propel the small object (bullet). About 0.3% of the gun powder energy is used to propel the gun back (recoil). Data: 22LR, 40 gr, 1255 FPS, 32 oz S&W handgun.
The reason the kick back doesn't kill the user is because the gun is significantly more heavy, thus slower moving and easier to stop. The smaller the gun, the more painful the kick. The larger the gun, the slower it moves, and the more time it takes to absorb the momentum, which can be good or bad depending on the situation. Though not frequently noticed, smaller guns can potentially be returned to their target after recoil significantly quicker than larger guns, because in smaller guns the momentum is being stopped more suddenly.
If you are being lifted from a standing position, 'kick off' a little by jumping as you are being lifted. The momentum this gives you will at least make it easier to lift you for the first few moments.
The action (foot to ball) and reaction (ball to foot) forces are equal and opposite. The ball gains momentum and the foot loses momentum. The collision is elastic and the foot has more mass than the football, so the football departs with a velocity greater than the initial velocity of the foot.

Vibrations
initial velocity of the kick = 28.06 m/s
Only when fired. Yes, they have a significant amount of recoil (kick)
yes but you will get fired
The kick it has when fired.

Many terms are used in American football. These terms include a down, a period of uninterrupted play, a field goal, a goal obtained from a kick, and a kickoff, the kick that begins a play.
as you run while dribbling with the ball, you lift up your foot to kick the ball and drive it into the goal...the power/momentum comes from the ground-hips-back down to your foot and transfers energy to the ball.
Yes, every action has an equal and opposite reaction.
bite, punch, kick, use weapon
The "kick" of a rifle- properly called recoil- is an example of REACTION- to the ACTION of the bullet being fired. "For every action, there is an equal and opposite reaction." The bullet going one way results in the gun being pushed the other way.
An idle ball because the reverse momentum of a rolling ball makes it harder to kick far.
