movement or motion
The answer is motion
reference point
a body is said to be at rest if it does not change its position with time with respect to a reference point
A.displacement B.acceleration C.speed D.velocity
movement or motion
A reference point is part of the definition of movement or displacement. The difference, over time, of your distance or orientation to a given reference point or points defines movement.
A reference point is part of the definition of movement or displacement. The difference, over time, of your distance or orientation to a given reference point or points defines movement.
The movement in relation to a frame of reference is called relative motion. A frame of reference is a system of object that are not moving with respect to one another.
The answer is motion
reference point
This depends entirely upon the direction of movement from the point of reference '0'
vector representing a change in position of a body or point with respect to a reference point, Displacement may be linear or angular.

To support you in specifying how the reference point is placed and how the object is moved away from the reference point.
