Precession (mechanical)

Precession is the phenomenon where the axis of a rotating body moves in response to an external force, resulting in a change in the orientation of that axis over time without a change in the rotational speed of the object itself. In mechanical terms, this typically occurs in systems such as gyroscopes and spinning tops. When an external torque is applied to a spinning object, rather than tipping over in the direction of the torque, the object will move in a direction perpendicular to the applied force.
