टॉर्क किस रैखिक मात्रा का घूर्णी एनालॉग है?

Force
बल

Mass
द्रव्यमान

Acceleration
त्वरण

Velocity
वेग

Torque is the rotational equivalent of force. Just as force causes linear acceleration, torque causes rotational acceleration. The relationship is:

\tau = r \times F

where $r$ is the lever arm and $F$ is the force applied. In Newton’s second law for rotation, $\tau = I\alpha$ .
