Angular acceleration is produced by
Correct answer: C. Torque
- A. Momentum
- B. Angular momentum
- C. Torque
- D. Force
Explanation
Angular acceleration is produced by torque according to Newton's second law for rotation, which states that the net torque acting on an object is equal to the moment of inertia times the angular acceleration.

About Angular and Linear Quantities
Rotational motion relates angular displacement, angular velocity and angular acceleration to linear displacement, tangential velocity and tangential acceleration through the radius. Questions use radians, v equals r omega and tangential acceleration, while distinguishing tangential velocity from centripetal acceleration and angular quantities from their linear counterparts.
