The turning effect of force is called_________?
Correct answer: C. Torque
- A. Moment
- B. Momentum
- C. Torque
- D. None of these
Explanation
The turning effect of a force about a pivot is called torque, with magnitude τ = force x perpendicular distance and unit N m. Students may choose moment because moment is also used for this quantity, but in this terminology torque is the intended answer.

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.
