# Rotation (disambiguation)

The term**can be used in several way and includes various topics. Generally, it's used to denote the rotation of movement of a rigid body in such a way that any given point of that body remains at a constant distance from some other fixed point**

*rotation*More specifically, it is applicable to:

- The farming pratice of crop rotation.
- The business management approach of job rotation.
- The International Earth Rotation and Reference Systems Service monitors the Earth's rotation.

- The differential rotation of objects.
- The Galaxy rotation problem concening discrepancy between the observed rotation.
- The optical rotation polarization.
- The reverse rotation effect being an optical illusion.
- The rotation curve for the variation in a circular orbital.
- The synchronous rotation of orbiting bodies.

- The axis, such that a geometric figure can be rotated.
- The rotation group which contains all 3D rotations
- A coordinate rotation is the transformation of coordinate systems.
- An improper rotation producing an inversion.
- The symmetry of an operation which rotates an object using a point on that object as its center.

- An order operation that may be performed on a set of pitcheses or pitch classes, where the last member is placed first. Sets which may be mapped onto each other through rotation are rotationally equivalent. See: transformation, permutation

In baseball pitching, the rotation is the group of starting pitchers for a team, and the order in which they pitch.
