A reference point is a place or object used for comparison to determine if something is in motion. An object is in motion if it changes position relative to a reference point. Objects that are fixed relative to Earth – such as a building, a tree, or a sign - make good reference points.
Answer:
angular velocity
Explanation:
In physics the quantity represented by is the <u>angular velocity, </u>the units of the angular velocity are radians/second.
This is a quantity that represents the speed when the movement of an object follows a circular path.
Mathematically defined as follows:
