The physical quantity that produces angular acceleration in the body is
Correct answer: D. torque
- A. force
- B. moment of inertia
- C. impulse
- D. torque
Explanation
Torque applied to a body produces angular acceleration.The formula for torque is:Where:- is the torque,- is the lever arm (perpendicular distance from the axis of rotation to the point where the force is applied),- is the force applied

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.
