Explanation:
Detailed explanation-1: -A reference point is a place or object used for comparison to determine if something is in motion. An object is in motion if it changes position relative to a reference point. Objects that we call stationary-such as a tree, a sign, or a building-make good reference points.
Detailed explanation-2: -The state of motion of an object is defined by its velocity-the speed with a direction.
Detailed explanation-3: -A position is an object’s distance in a certain direction from a reference point. A complete description of your position includes a distance, a direction, and a reference point.
