We now understand that the torque is causing the spin angular momentum to change but the motion still seems mysterious. We shall try to understand why the angular momentum changes direction by first examining the role of force and impulse on a single rotating particle and then generalize to a rotating disk.

The gyroscope has various uses as a children's toy (where it is similar to a top), as an apparatus for demonstrating principles of physics, or as an instrument for navigation.
