A relative reference.
Relative motion is movement in relation to a frame of reference.
The location of an object in space is called its position. This can be described using coordinates such as latitude, longitude, and altitude in relation to a reference point.
A reference point is needed to describe a location because it provides a consistent and universal way to communicate the position of an object or place in relation to other objects or places. By using a reference point, we establish a common frame of reference that enables accurate communication and understanding of spatial relationships.
An object's location should include its position in relation to nearby objects, its distance from a reference point or landmark, and its orientation or direction in relation to cardinal points such as north, south, east, or west.
A reference point is used as a comparison to determine if an object is in motion. This reference point can be a stationary object or a specific location that helps observers detect movement in relation to it.
A reference point is an object or point from which movement is determined. It serves as a fixed location or frame of reference that helps to describe the motion of other objects or points in relation to it.
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.

A common frame of reference when describing motion is the observer's point of view or a fixed point in the environment that is used as a reference to describe the motion of an object. This helps to establish direction, speed, and location of the object in relation to the observer or the fixed reference point.
The term for a geographic location's height above sea level is elevation. Elevation is usually measured in meters or feet and provides a reference point for understanding a location's position in relation to sea level.
