It is displacement.
Yes, that is one meaning of "reference point", although the reference point need not be an object, but may simply be a location.
No because enable to see if the object is moving it needs a reference point other than itself.
To support you in specifying how the reference point is placed and how the object is moved away from the reference point.
a reference point i just had that test a while ago!
A Reference Point A reference point is needed to determine if an object is in motion.

Its position, relative to the point of reference.

A Reference Point A reference point is needed to determine if an object is in motion.
An object is in motion only if its distance from a reference point is changing. The average speed of the object is given by the object's rate of change of displacement from the reference point over time.
To help you state how the reference point placement is and how the object is moved from the reference point
The height of an object above a reference point is its potential energy with reference to that point.
This is usually called a reference point. Frame of reference is not an incorrect term, but it is used less frequently.
