precession
- Definição1
- One of the two basic characteristics of a gyroscope. The other basic characteristic is rigidity in space. Precession causes a force applied to a spinning gyroscope to be felt, not at the point the force is applied, but at a point 90º in the direction of rotation from that point.

- Contexto
- Precession is the tilting or turning of a gyro in response to pressure. The reaction to this pressure does not occur at the point where it was applied; rather, it occurs at a point that is 90° later in the direction of rotation from where the pressure was applied. This principle allows the gyro to determine a rate of turn by sensing the amount of pressure created by a change in direction. Precession can also create some minor errors in some instruments.
