Torque acting on a body determines_______________?
Correct answer: C. Angular acceleration
- A. Acceleration
- B. Linear acceleration
- C. Angular acceleration
- D. Direction of motion of the body
Explanation
Torque is the rotational analogue of force and produces angular acceleration according to τ = Iα, where τ is torque in N m, I is moment of inertia in kg m², and α is angular acceleration in rad s^-2. It does not directly determine linear acceleration unless the body's rotation is linked to translation. Students may choose b by applying Newton's second law, F = ma, to a rotational situation.

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.
