For example, gas-operated shotguns are widely held to have a "softer" recoil than fixed breech or recoil-operated guns (although many semi-automatic recoil and gas-operated guns incorporate recoil buffer systems into the stock that effectively spread out peak felt recoil forces.) In a gas-operated gun, the bolt is accelerated rearwards by ...
Free recoil / Frecoil is a vernacular term or jargon for recoil energy of a firearm not supported from behind. Free recoil denotes the translational kinetic energy ( E t ) imparted to the shooter of a small arm when discharged and is expressed in joules (J), or foot-pound force (ft·lb f ) for non-SI units of measure.
Let m b and v b stand for the mass and velocity of the bullet, the latter just before hitting the target, and let m t and v t stand for the mass and velocity of the target after being hit. Conservation of momentum requires m b v b = m t v t. Solving for the target's velocity gives v t = m b v b / m t = 0.016 kg × 360 m/s / 77 kg = 0.07 m/s = 0 ...
Also, recoil can alternatively be measured by recoil velocity or recoil energy instead of by recoil impulse. An alternative formula for simplified recoil measurement which also takes into account firearm weight, gun powder weight and the velocity of the gun powder gases has been suggested: [6]
The general formula for the kinetic energy is =, where v is the velocity of the bullet and m is the mass of the bullet. Although both mass and velocity contribute to the muzzle energy, the muzzle energy is proportional to the mass while proportional to the square of the velocity. The velocity of the bullet is a more important determinant of ...
For similar decay energies, the recoil from emitting an alpha ray will be much greater than the recoil from emitting a neutrino (upon electron capture) or a gamma ray. For decays that produce two particles as well as the daughter nuclide, the above formulas can be used to find the maximum energy, momentum, or speed of any of the three, by ...
A rotational inertia based formula similar to Robins' was derived by French mathematician Siméon Denis Poisson and published in The Mécanique Physique, for measuring the bullet velocity by using the recoil of the gun: = ′ where: is the mass of the bullet
Recoil operation is an operating mechanism used to implement locked-breech autoloading firearms. ... Ejecta mass × ejecta velocity = recoiling mass × recoil velocity.
