1. Rotation

   A rotation is a circular movement of an object around a center of rotation. A three-dimensional object rotates always around an imaginary line called a rotation axis. If the axis is within the body, and passes through its center of mass the body is said to rotate upon itself, or spin. A rotation about an external point, e.g. the Earth about the Sun, is called a revolution or orbital revolution, typically when it is produced by gravity.

Examples of rotation in a Sentence

1. Del Coro:

   Smaller sustainable farms that practice healthy crop rotation will have more nutritious crops.

2. Guy Houlsby:

   The original Darrieus turbine has blades that are parallel to the axis of rotation, and that means that the loads in the blades are carried entirely by bending of the blades. That results in very high stresses, the re-design that we've done changes the blades so that they form this triangulated structure, and that's a very stiff and very strong structural form. And that means that the loads in the blades are principally carried by axial forces and that means that the stresses are much lower.

3. Jeff Jonas:

   I think the more general sector rotation has probably created a high bar for these companies, and I am a little worried that meeting expectations isn't even enough.
