 * Ballistics**: the study of projectiles (bullets) and firearms
 * Barrel**: the long, metal tube that guides a projectile out of a firearm
 * Breech**: the end of the barrel attached to the firing mechanism of a firearm where the cartridge is loaded and unloaded
 * Bullet:** a pointed projectile
 * Caliber**: a measure of the inside diameter of a firearm barrel
 * Cartridge**: case that holds a bullet, primer powder, and gun powder
 * Firearm**: a weapon capable of firing a projectile using a confined explosive as a propellant
 * Fully Automatic**: a firearm with a clip-fed mechanism that fires repeatedly as long as the trigger is pressed
 * Gunshot Residue**: (GSR) the tiny particles expelled from a firearm when it is fired
 * Lands** and **Grooves**: the ridges (lands) and depressions (grooves) found on the inside of a firearm's barrel that are created when the firearm is manufactured
 * Muzzle**: the end of the barrel which the projectile exits from a firearm
 * Pistol**: a handheld firearm
 * Revolver**: a pistol with a revolving cylinder

 * Shell Casing:** the metal (usually brass) housing for the gunpowder of a firearm
 * Trajectory**: the path of flight of a projectile
 * Internal Ballistics**: the study of the processes originally accelerating the projectile, for example the passage of a bullet through the barrel of a rifle
 * Transition Ballistics** (Intermediate Ballistics): the study of the projectile's behavior when it leaves the barrel and the pressure behind the projectile is equalized
 * External Ballistics:** the study of the passage of the projectile through space or the air
 * Terminal Ballistics**: the study of the interaction of a projectile with its target
