Question

Rotational Analogue of force in linear motion is

• A. Weight
• B. Angular Momentum
• C. Moment of Inertia
• D. Torque

Answer 1

The correct option is D Torque

Rotational Analogue of force in linear motion is torque.

$\overrightarrow{\tau }=\overrightarrow{r}\times \overrightarrow{F}$

Force is necessary for a body to do translational motion. Similarly it is the torque which is required to rotate a body. If net torque applied on the body about the axis of rotation is zero, then the body doesnot rotate.
