Torque is defined as______________?
Correct answer: D. All A, B and C are correct
- A. Turning effect of force
- B. Cross product of position vector and force
- C. Product of force and moment arm
- D. All A, B and C are correct
Explanation
Torque is the turning effect of a force and is defined vectorially by τ = r x F, while its magnitude is force multiplied by the perpendicular moment arm. Since A, B, and C all describe torque correctly, option d follows. Students may choose a because it is the simplest definition, but it is not the only correct statement.

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.
