What is the science of ballistics?
Ballistics is a branch of engineering that deals with the motion and behaviour of projects such as bullets rockets bombs and guided missiles. Research in ballistics is conducted by the armed forced of a number of countries. Ballistics is divided into three main branches; interior, exterior and terminal ballistics. Police use a science called forensic ballistics. Interior ballistics deals with the motion of a projectile as it travels down the barrel of a weapon, such as a rifle, pistol or rocket launcher. A person studying the interior ballistics of a rifle bullet, for example, would have to know the weight of the bullet, the pressure placed on the bullet by the exploding powder charge, the speed at which the bullet travels down the barrel, the length of the barrel and the speed with which the bullet leaves the muzzle of the rifle. The speed with which a projectile leaves a gun barrel or a missile leaves a launcher is called the initial velocity or muzzle velocity. This velocity varies
