Question

Which of the following option denotes the direction of the angular acceleration (A) Along the direction of angular velocity. (B) Opposite to the direction of angular velocity. (C)Does not depend on direction of angular velocity. (D)Both(A)and(B)

Answer 1

Answer:

A) Along the direction of angular velocity.

Explanation:

Angular acceleration, also called rotational acceleration, is a quantitative expression of the change in angular velocity that a spinning object undergoes per unit time. The direction of the angular acceleration vector is perpendicular to the plane in which the rotation takes place
