The turning effect of force is called _________?
Show answer Hide answer
Answer: C. Torque
Explanation
Torque measures the rotational force applied to an object causing it to turn. Physics defines the turning effect of a force around a pivot point as torque. Multiplying applied force by the lever arm distance yields the resulting torque value. Rotational dynamics use torque to analyze how objects start or stop spinning. The standard SI unit for measuring torque is the newton meter. Applying force at a distance from an axis creates the rotational turning effect.
Mechanics use wrenches to apply torque when tightening bolts and automotive fasteners. Engine specifications highlight torque ratings to describe vehicle acceleration performance. Physics students calculate torque problems to understand levers and rotational equilibrium. Moment is an alternate term sometimes used but torque is the precise physical descriptor. Momentum refers to mass in motion rather than the turning effect of a force. Claiming none of these is wrong because torque is the exact scientific term for the effect.
