.500 S&W Magnum: Recoil impulse of 3.76 lb f ·s (16.7 N·s); Recoil velocity of 34.63 ft/s (10.6 m/s); Recoil energy of 65.17 ft⋅lb f (88.4 J) In addition to the overall mass of the gun, reciprocating parts of the gun will affect how the shooter perceives recoil.
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 ...
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.
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
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]
Recoil operation is an operating mechanism used to implement locked-breech autoloading firearms. ... Ejecta mass × ejecta velocity = recoiling mass × recoil velocity.
In nuclear physics, atomic recoil is the result of the interaction of an atom with an energetic elementary particle, when the momentum of the interacting particle is transferred to the atom as a whole without altering non-translational degrees of freedom of the atom.
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 ...
