A. A measurement that measures distance travelled per unit of time in circular motion. B. A measurement that measures the number of rotation per unit of time in a circle motion. C. A Measurement that measures, how much force was applied to a rotation.
Linearspeedis the distance traveled per unit of time, whiletangential speed(ortangentialvelocity) is the linearspeedof something moving along a circular path.
