Which physics term is defined as a continuing change of position?

The term that is defined as a continuing change of position is motion. Motion refers to the change in the position of an object with respect to a reference point over time. It encompasses various aspects such as direction, speed, and the path taken. This definition captures the essence of what it means for an object to be in motion, highlighting the fundamental relationship between time and the change in position.

In contrast, force is a push or pull acting on an object that can cause it to accelerate, while acceleration specifically refers to the rate of change of velocity over time. Velocity, on the other hand, is a vector quantity that describes the speed of an object in a given direction. Although these terms are interconnected within the study of physics, they each describe different concepts. Motion, by definition, is the broad category under which all these other concepts reside, making it the most accurate choice for the given definition.
