The path that a moving object follows through space as time progresses is called its trajectory. This describes the route the object takes, including where it is at each moment, and how that path changes as time goes on. In physics, you think of position as a function of time, r(t), and from that you get velocity and acceleration as derivatives, which tell you how fast and in what direction the object is moving and how those quantities are changing along the path. In forensic contexts, analyzing trajectory helps reconstruct events—where a projectile or body traveled, where it came from, and where it ended—by interpreting the spatial path over time. The other terms refer to injury, a method of harm, or a surgical instrument, not to the motion through space.
