Answer:
object's angular velocity
Step-by-step explanation:
For an object to rotate about an axis, each point on the object has the same angular velocity. The tangential speed of any point is proportional to its distance from the axis of rotation. Angular velocity units are radians / second.
In circular motion, angular velocity is the magnitude that characterizes the speed with which the angle swept by the line that joins the rotating particle with the center of rotation varies.
