benchmark number
But
The coordinate of that number.
It is the number that represents the distance of the point from the origin, or zero. It may be called the coordinate.
The position of the particle can be given by a number representing the distance of the particle from some fixed reference point (called the origin). This is not enough to describe the motion of the particle since for that you also required the time (or times) at which the particle is at any particular point.
origin
It is called the digit in the first decimal place.
reference point
reference point
It is the point, number or place used to compare another point, number or place
This is usually called a reference point. Frame of reference is not an incorrect term, but it is used less frequently.

It is because many things are measured with reference to a fixed point: it space or time. This point is called a reference point or origin.
Motion
The medical term for position above the point of reference is "superior."
It is a representation where the distance from a reference point - the origin - represents the value of the number.
A landmark - or reference point.
This is called a reference point.
A change in an objects position relative to a reference point is called motion.
