What does motion necessarily involve?

Motion necessarily involves a change in position. When an object is said to be in motion, it means that its location is changing over time relative to a reference point. This change can occur in different directions and distances, which defines motion. Position is a crucial concept because it establishes where an object is located at a given time, and for motion to occur, that location must alter.

While changes in velocity, time, or speed may occur as an object moves, they are not prerequisites for defining motion itself. Motion is fundamentally about the displacement of an object from one point to another, thereby directly linking it to a change in position.
