To determine if an object is in motion, you need to compare its position with a reference point. If the object changes its position relative to the reference point over time, then it is in motion. For example, if a car moves along a road and you see it getting farther away from a tree, you can say that the car is in motion. If the object stays in the same position without changing, it is not in motion. Motion is observed when something moves from one place to another.
