A **rotation** is a circular movement of an object around a center (or point) of rotation. A three-dimensional object can always be rotated around an infinite number of imaginary lines called *rotation axes* (**pole**.

All rigid body movements are rotations, translations, or combinations of the two.

A rotation is simply a progressive radial orientation to a common point. That common point lies within the axis of that motion. The axis is 90 degrees perpendicular to the plane of the motion. If the axis of the rotation lies external of the body in question then the body is said to orbit. There is no fundamental difference between a “rotation” and an “orbit” and or "spin". The key distinction is simply where the axis of the rotation lies, either within or outside of a body in question. This distinction can be demonstrated for both “rigid” and “non rigid” bodies.

If a rotation around a point or axis is followed by a second rotation around the same point/axis, a third rotation results. The reverse (

Rotations around the *x*, *y* and *z* axes are called *principal rotations*. Rotation around any axis can be performed by taking a rotation around the *x* axis, followed by a rotation around the *y* axis, and followed by a rotation around the *z* axis. That is to say, any spatial rotation can be decomposed into a combination of principal rotations.

In *yaw*, *pitch*, and *roll*
