This roughly halves the energy that the spring needs to absorb, and also roughly halves the peak force conveyed to the mount, as compared to the usual system.

In a soft-recoil system, the spring (or air cylinder) that returns the barrel to the forward position starts out in a nearly fully compressed position, then the gun's barrel is released free to fly forward in the moment before firing; the charge is then ignited. Like pushing softer or harder on the brakes of a car, the driver feels less or more deceleration force being applied, over a longer or shorter distance to bring the car to a stop. One of the common ways of describing the felt recoil of a particular gun-cartridge combination is as "soft" or "sharp" recoiling; soft recoil is recoil spread over a longer period of time, that is at a lower deceleration, and sharp recoil is spread over. However, for the human body to mechanically adjust recoil time, and hence length, to lessen felt recoil force is perhaps an impossible task.

This means that: int _0t_crF_cr(t dt-m_fv_fm_pv_p where: Fcr(t)displaystyle F_cr(t is the counter-recoil force as a function of time ( t ) tcrdisplaystyle t_cr, is duration of the counter-recoil force A similar equation can be written for the recoil force on the firearm: 0trFr(t)dtmfvfmpvpdisplaystyle int _0t_rF_r(t. However, one should understand that total recoil momentum is slightly more than the simple product of the mass and velocity of the exiting projectile, for this reason.

The effective velocity may be used in the energy equation as well, but since the value of used is generally specified for the momentum equation, the energy values obtained may be less accurate. The bullet receives about 2685 foot-pounds of energy, and the rifle only.5 ft-lbs of energy, even though the rifle and the bullet both receive about.89 pound-sec momentum. They are used often as light anti-tank weapons. The source of the kinetic energy is the heat energy rapidly released during propellant combustion. Assuming a near free-recoil condition, and neglecting the gases ejected from the barrel, (an acceptable first estimate then immediately after firing, conservation of momentum requires that the total momentum of the firearm and projectile is the same as before, namely zero. However, the shooter's body assumes the role of gun mount, and must similarly dissipate the gun's recoiling momentum over a longer period of time than the bullet travel-time in the barrel, in order not to injure the shooter.
