Detailed explanation-1: -So it is not a rotational analogue of force in linear motion. Angular momentum: In linear motion the linear momentum of a body gives a measure of its translator motion. Analogous to linear momentum the angular momentum gives the measure of turning motion of the body.

Detailed explanation-2: -Torque is the turning effect of force or rotational force. Torque is the product of the magnitude of the force and perpendicular distance from the axis of rotation to the point where force is being applied. Hence, a rotational analog of force is Torque.

Detailed explanation-3: -Hence, the rotational analogue of force is torque.

Detailed explanation-4: -Force is necessary for a body to do translational motion. Similarly it is the torque which is required to rotate a body.

Detailed explanation-5: -Torque is a twisting or turning force that tends to cause rotation around an axis, which might be a center of mass or a fixed point. Torque can also be thought of as the ability of something that is rotating, such as a gear or a shaft, to overcome turning resistance.
