Forensics – Crime Scene Practice Test

Ballistic trajectory reconstruction centers on how a bullet travels through space after it leaves the gun. It uses physics—gravity, air resistance, wind—to model the projectile’s flight and to infer where the shooter was, the distance, and the angle of fire. This is why the path of a projectile through space is the best answer: trajectory analysis is all about mapping that flight path and linking it to the events at the scene. The chemical composition of gunpowder matters for understanding ammunition and indications of the weapon’s characteristics, but it doesn’t describe how the bullet moves. DNA analysis can identify a shooter, but that’s a biological method, not a study of the projectile’s path. The brand or model of firearm is part of weapon identification, not the flight path.
