Instantaneous angular speed is:
A)total angular displacement divided by time
B)the integral of the displacement over time
C)the rate at which the angular acceleration is changing
D)the magnitude of the instantaneous angular velocity
E)a vector directed along the axis of rotation

Question

Quizplus · Accepted Answer

Instantaneous angular speed refers to the magnitude of the instantaneous angular velocity, which is the rate at which an object is rotating around an axis at a given instant of time. Therefore, choice D is the correct answer. Choice A describes average angular speed, choice B describes total angular displacement, choice C describes angular jerk, and choice E describes angular momentum direction.
