## Definition

the study of how objects move through the air, especially when they are fired from a gun or thrown. It looks at things like speed, direction, and how far something travels.

For teachers: the branch of physics concerned with the motion of projectiles, including the effects of gravity and air resistance. Often used in the context of military science or forensic analysis.

## Examples

- The police used ballistics to match the bullet to the suspect's gun.
- Military engineers study ballistics to improve the accuracy and range of long-range artillery systems.
- Advanced ballistics research has led to the development of non-lethal rounds that can incapacitate a target without causing permanent physical damage to the surrounding environment.
