Answer 1

Answer:

a position from which to measure future distance  

Explanation:

Reference point is a standard point taken as a fixed point for future measurement. Example, consider a ball is at height h. Here height h is measured from the surface of earth. So, the surface of earth is taken as a reference point for future measurement. In all measurements from that time is taken from the surface of the earth.
