  2. Projectile motion - Wikipedia

    en.wikipedia.org/wiki/Projectile_motion

    Free body diagram of a body on which only gravity and air resistance act. The free body diagram on the right is for a projectile that experiences air resistance and the effects of gravity. Here, air resistance is assumed to be in the direction opposite of the projectile's velocity: F a i r = − f ( v ) ⋅ v ^ {\displaystyle \mathbf {F ...

  3. Ballistic coefficient - Wikipedia

    en.wikipedia.org/wiki/Ballistic_coefficient

    The standard model projectile is a "fictitious projectile" used as the mathematical basis for the calculation of actual projectile's trajectory when an initial velocity is known. The G1 model projectile adopted is in dimensionless measures of 2 caliber radius ogival-head and 3.28 caliber in length.

  4. Ballistics - Wikipedia

    en.wikipedia.org/wiki/Ballistics

    A projectile is any object projected into space (empty or not) by the exertion of a force. Although any object in motion through space (for example a thrown baseball) is a projectile, the term most commonly refers to a weapon. [8] [9] Mathematical equations of motion are used to analyze projectile trajectory. [citation needed]

  5. Projectile - Wikipedia

    en.wikipedia.org/wiki/Projectile

    In projectile motion the most important force applied to the ‘projectile’ is the propelling force, in this case the propelling forces are the muscles that act upon the ball to make it move, and the stronger the force applied, the more propelling force, which means the projectile (the ball) will travel farther. See pitching, bowling.

  6. 5-inch/38-caliber gun - Wikipedia

    en.wikipedia.org/wiki/5-inch/38-caliber_gun

    The Projectile (pictured) has three major parts: the body, the fuze, and the explosive charge. [5] Projectile body. The body is basically a machined steel tube with an ogive shape at one end. At the ogive and rear ends are threaded openings used to the install the shell's filler and hold the fuzes.

  7. Armour-piercing ammunition - Wikipedia

    en.wikipedia.org/wiki/Armour-piercing_ammunition

    Armour-piercing ammunition (AP) is a type of projectile designed to penetrate armour protection, most often including naval armour, body armour, and vehicle armour. [1]The first, major application of armour-piercing projectiles was to defeat the thick armour carried on many warships and cause damage to their lightly armoured interiors.

  8. Bullet - Wikipedia

    Hard cast solid bullet (left), with gas check (center) and lubrication (right) A modern centerfire cartridge consisting of the following: 1. bullet, as the projectile; 2. metallic case, which holds all parts together; 3. propellant, for example gunpowder or cordite;4. rim, which provides the extractor on the firearm a place to grip the case to ...

  9. Contact force - Wikipedia

    en.wikipedia.org/wiki/Contact_force

    Not all forces are contact forces; for example, the weight of an object is the force between the object and the Earth, even though the two do not need to make contact. Gravitational forces, electrical forces and magnetic forces are body forces and can exist without contact occurring.
