Also known as moment of force

In physics and mechanics, torque is the rotational correspondent of linear force. It is also referred to as the moment of force, or simply the moment. Just as a linear force is a push or a pull applied to a body, a torque can be thought of as a twist applied to an object with respect to a chosen axis. For example, driving a screw uses torque to force it into an object. The torque is applied by the screwdriver, rotating around its axis, to the drive on the head of the screw.

AI overview

Torque is a twisting force that causes objects to rotate around an axis, similar to how a regular push or pull force causes objects to move in a straight line. It matters because many everyday tasks—like driving a screw with a screwdriver—depend on torque to work.
