Ballistic refers to anything related to projectiles and the science of their motion, especially when they are launched, fired, or thrown through the air. The term is most commonly used in military, forensic, and engineering contexts to describe the behavior, performance, and impact of bullets, missiles, and other high-speed objects. Ballistic analysis helps experts understand factors such as trajectory, velocity, and force, making it essential for weapon design, accident investigation, and criminal examination. More broadly, the word can also describe movement that is rapid, forceful, and difficult to control.
