Question

what is a reference point ?​

Answer 1

Answer:

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 are fixed relative to Earth – such as a building, a tree, or a sign - make good reference points.

Answer 2

• 'Reference point' means the point or object from which the entity in question is in movement. It's being used as a comparative point that helps evaluate a body's movement. It is because of the reality that the movement is relevant to a subject.
