The dimension of torque is______________?
Correct answer: A. [ML2T-2]
- A. [ML2T-2]
- B. [MLT-2]
- C. [ML2T]
- D. [ML-2T-2]
Explanation
Torque is force multiplied by distance, so its dimensions are [MLT^-2] x [L] = [ML2T^-2]. This is also the dimension of energy, although torque and energy are different physical quantities. Students may choose b by using only the dimensions of force and forgetting the additional length factor.

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.
