What is torque? Crudely speaking, torque is "twisting or turning ability" of a force that can: change the angular velocity of an object (i.e. speed up or slow down rotation) cause a twisting or bending distortion of an object. A force with a "line of action" that does not cross the axis of rotation results in torque. Note:
Torque. Why is a door knob located as far as possible from the door hinge? When you want to push open a door, you apply a force. Where you apply the force and in what direction you push are also important.
The definition of angular momentum (or the moment of momentum) J for a single particle : J = r p. is the displacement vector from the origin and p the momentum. The direction of the angular momentum gives the direction perpendicular to the plane of motion. Differentiate:

Torque is the rotational equivalent of a force. It is a measure of the effectiveness of a force in changing or accelerating a rotation (changing the angular velocity over a period of time). In equation form, the magnitude of torque is defined to be. τ = rF sin θ.

Torque Introduction. Two general types of motion: Translational Motion: The center of mass moves from one location to another location. Caused by a net force. Force is the ability to cause an acceleration of an object. Rotational Motion: The object moves in circular motion about its center of mass. Caused by a net torque.
