1. Rotation

   Rotation, or spin, is the circular movement of an object around a central axis. A two-dimensional rotating object has only one possible central axis and can rotate in either a clockwise or counterclockwise direction. A three-dimensional object has an infinite number of possible central axes and rotational directions. If the rotation axis passes internally through the body's own center of mass, then the body is said to be autorotating or spinning, and the surface intersection of the axis can be called a pole. A rotation around a completely external axis, e.g. the planet Earth around the Sun, is called revolving or orbiting, typically when it is produced by gravity, and the ends of the rotation axis can be called the orbital poles.

1. rotation

   Rotation refers to the movement or circular motion of an object, element, or entity around a center or axis. It could occur in a two-dimensional or three-dimensional spaces. This term is commonly used in various fields like physics, mathematics, astronomy, and more. Rotation can also refer to a specific turn or cycle in a sequence or order of events.

1. Rotationnoun

   the act of turning, as a wheel or a solid body on its axis, as distinguished from the progressive motion of a revolving round another body or a distant point; thus, the daily turning of the earth on its axis is a rotation; its annual motion round the sun is a revolution

2. Rotationnoun

   any return or succesion in a series

3. Rotationadjective

   pertaining to, or resulting from, rotation; of the nature of, or characterized by, rotation; as, rotational velocity

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. Bill White:

   Just one rotation of the turbine will power an entire Massachusetts house for a day. It's staggering, there has been an extraordinary acceleration of the technology.

2. Ernesto Ambrosetti:

   Corn and wheat will start occupying a bigger area, that rotation will set the stage for sustainable productivity.

3. 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.

4. Dennis McCarthy:
