What is torque?

  • (noun): A twisting force.
    Synonyms: torsion


Torque, moment or moment of force (see the terminology below), is the tendency of a force to rotate an object about an axis, fulcrum, or pivot. Just as a force is a push or a pull, a torque can be thought of as a twist to an object. Mathematically, torque is defined as the cross product of force and the lever-arm distance, which tends to produce rotation.
