The physical quantity which produces angular acceleration in the body is
Correct answer: D. Torque
- A. Force
- B. Moment of inertia
- C. Impulse
- D. Torque
Explanation
This is correct. Torque is the rotational equivalent of force, and it's defined as the product of the force applied and the distance from the axis of rotation at which the force is applied. It's the torque that ultimately causes angular acceleration in a body.

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.
