What are the three kinds of ballistics?

The three kinds of ballistics are internal, external, and terminal, which collectively encompass the entire process of projectile motion and behavior.

Internal ballistics refers to the behavior of the projectile within the firearm from the moment of ignition to the exit of the projectile from the barrel. This includes factors such as the pressure build-up from the ignited gunpowder and the dynamics of the projectile being propelled through the barrel.

External ballistics deals with the flight of the projectile after it exits the barrel and before it reaches the target. This includes studying the effects of gravity, air resistance, wind, and other environmental factors that influence the projectile's trajectory.

Terminal ballistics focuses on what happens when the projectile strikes the target, including the effects of impact, penetration, and damage to the target material. Understanding terminal ballistics is crucial for assessing the effectiveness of a projectile in various applications, like military or law enforcement scenarios.

The other answer choices represent different categorization methods but don't encompass the fundamental concepts of ballistics. Centerfire, rimfire, and shotgun refer to types of ammunition rather than a ballistic classification. Handgun, rifle, and shotgun describe firearm categories instead of covering the ballistic processes. Target, tactical, and competitive relate to shooting disciplines rather than the scientific
