Which term reflects the change in position of a body in relation to time?

The term that reflects the change in position of a body in relation to time is motion. Motion describes the change in an object's position over time and is fundamental to understanding physical dynamics. When an object moves from one place to another, its location changes, which can be quantified by observing the time it takes to cover the distance between the starting point and the endpoint.

Acceleration refers to the rate of change of velocity and is related to how quickly an object changes its speed or direction during its motion. Velocity, on the other hand, specifically describes the speed of an object in a given direction, which is a component of motion but does not encompass the entire concept. Path refers to the route an object takes during its motion, but it does not directly reflect the overall relationship between position and time. Therefore, motion is the most accurate term that encompasses the change in position of a body with respect to time.
