This introduction to ballistics is an overview of the essentials involved in the mathematical modeling of the ballistics that pertain to a bullet that is fired from a firearm. This book gives an overview into the classical mechanics of ballistics which includes everything from the internal, transitional, external and terminal ballistics to the equations of motion, trajectory, hydrostatic shock and Stokes' Law. Included are sections on ranged weapons, propellants, firearm, bullet and barrel design. A section on stopping power is especially noteworthy as this is often the factor that drives the design of the weapon. This edition also includes some of the latest ballistics studies from the war in Iraq.
