Pellet exiting muzzle, with formula for energy overlaid.. Muzzle energy is the kinetic energy of a bullet as it is expelled from the muzzle of a firearm. Without consideration of factors such as aerodynamics and gravity for the sake of comparison, muzzle energy is used as a rough indication of the destructive potential of a given firearm or cartridge.
A standard, unmodified Tokyo Marui gearbox will fire 0.20 g airsoft pellets at 240 to 300 feet per second (73 to 91 m/s) — around 0.8 to 0.9 joules (0.59 to 0.66 ft⋅lb) of muzzle energy – depending on the model. These gearboxes may be modified for higher performance with aftermarket parts, but Japanese law limits their power output to 0. ...
For projectiles in unpowered flight, its velocity is highest at leaving the muzzle and drops off steadily because of air resistance.Projectiles traveling less than the speed of sound (about 340 m/s (1,100 ft/s) in dry air at sea level) are subsonic, while those traveling faster are supersonic and thus can travel a substantial distance and even hit a target before a nearby observer hears the ...
Airsoft is safe when played with proper protective gear. Most airsoft guns on the market are usually below 350 ft/s (110 m/s), but projectiles expelled from any type of airsoft gun can travel as slow as 65 ft/s (20 m/s) to more than 700 ft/s (210 m/s) and are capable of breaking skin at 350–400 ft/s (110–120 m/s).

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.
Airsoft pellets (known as BBs) are spherical projectiles used by airsoft guns. Typically made of plastic , [ 1 ] they usually measure around 6 mm (0.24 in) in diameter (though selective models use 8 mm), [ 1 ] and weigh 0.20–0.40 g (3.1–6.2 gr), with the most common weights being 0.20 g and 0.25 g, while 0.28 g, 0.30 g, 0.32 g and 0.40 g ...
Calculating the Joules and energy generated by airsoft guns is important because of phenomena like "joule creep" where the FPS remains the same while the energy of the airsoft BB leaving the airsoft gun barrel increases. [22] Different regions vary in the velocity airsoft guns are allowed to shoot at.
