    en.wikipedia.org/wiki/Physics_of_firearms

    According to Newtonian mechanics, if the gun and shooter are at rest initially, the force on the bullet will be equal to that on the gun-shooter. This is due to Newton's third law of motion (For every action, there is an equal and opposite reaction). Consider a system where the gun and shooter have a combined mass m g and the bullet has a mass m b.

    en.wikipedia.org/wiki/Terminal_ballistics

    Light weight non-expanding projectiles pushed at a relatively high rate of speed are also utilized, generally for close ranged applications well inside 100 yards. The light for caliber bullets will transfer energy to a given medium more rapidly, yet with consistent penetration characteristics relative to their sectional density and a constant ...

    en.wikipedia.org/wiki/2A28_Grom

    The BMP-1 is unable to engage targets using the 2A28 "Grom" gun from some hull-down positions due to its limited depression, making it vulnerable to enemy fire. [8] The limited elevation of the main gun, its lack of firepower and inaccuracy against point targets at 500–700 metres (550–770 yd) meant that it could not fight effectively in the ...

  5. Internal ballistics - Wikipedia

    en.wikipedia.org/wiki/Internal_ballistics

    The bullet must tightly fit the bore to seal the high pressure of the burning gunpowder. This tight fit results in a large frictional force. The friction of the bullet in the bore does have a slight impact on the final velocity, but that is generally not much of a concern. Of greater concern is the heat that is generated due to the friction.

    en.wikipedia.org/wiki/Handgun_effectiveness

    Handgun effectiveness is a measure of the stopping power of a handgun: its ability to incapacitate a hostile target as quickly and efficiently as possible. Overview [ edit ]

  7. Sabot (firearms) - Wikipedia

    en.wikipedia.org/wiki/Sabot_(firearms)

    A sabot (UK: / s æ ˈ b oʊ, ˈ s æ b oʊ /, US: / ˈ s eɪ b oʊ /) is a supportive device used in firearm/artillery ammunitions to fit/patch around a projectile, such as a bullet/slug or a flechette-like projectile (such as a kinetic energy penetrator), and keep it aligned in the center of the barrel when fired.

  8. Kinetic energy penetrator - Wikipedia

    en.wikipedia.org/wiki/Kinetic_energy_penetrator

    The principle of the kinetic energy penetrator is that it uses its kinetic energy, which is a function of its mass and velocity, to force its way through armor. If the armor is defeated, the heat and spalling (particle spray) generated by the penetrator going through the armor, and the pressure wave that develops, ideally destroys the target. [3]

  9. Muzzle velocity - Wikipedia

    en.wikipedia.org/wiki/Muzzle_velocity

    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 ...
