Why does a description of position depend on a reference point?

Description of position depends on a reference point because there is no other way to do it. A reference point is observable, so based on that observation, you can then describe where something else is.
All locations are described that way, although there are many different kinds of reference points that are used. For example, a street address, 233 Main St., uses a street as a reference point. Mathematically, a Cartesian coordinate system is the most commonly used way to establish reference points. The use of lines of latitude and longitude allow is to locate anything on the surface of the Earth. If we wishes to locate another planet than the Earth, in our solar system, we would start by describing the distance of that planet from the sun.

What describes the position of an object?
a reference point i just had that test a while ago!
Does the displacement arrow depend on the choice of reference point?
Yes and no.Some use "displacement" only to describe a change in the position of an object from some initial starting point to some ending point. That is, there is a distinction between "position" and "displacement." The position would be defined relative to a reference point. In that case the arrow depends only on where the particle was and where it ended up and the reference point does not matter.Others use a definition for displacement which describes the difference between an object's position and a fixed reference point. That is, how far an object is displaced from a certain point even if the object had never been at that point. A distinction between position and displacement is not made. For this latter definition, the choice of reference point will make a difference in the direction of the arrow.In physics problems one usually only cares about the changes in position (and velocity, etc) and the choice of reference point will not affect these.
Does reference point depend on direction?
i don't think it does because reference point is a point with other points and lines connected to it so it doesn't depend on direction
Identify three pieces of information needed to describe an objects position?
1.)Distance from the reference point. 2.)A reference point. 3.)Direction from the reference point.
What is a change of position to a reference point called?
Motion

Where an object is with regard to a reference point is what?
Its position, relative to the point of reference.

A place or object used for comparison to determine if something is in motion is called what?
A landmark - or reference point.
What is the most common reference point for determining position and motion?
Earth's surface is a common reference point for determining position and motion.
What is the medical term meaning position above the point of reference?
The medical term for position above the point of reference is "superior."
