Rotation

In physics, angular momentum (rarely, moment of momentum or rotational momentum) is the rotational analog of linear momentum.

In Newtonian mechanics, the centrifugal force is an inertial force (also called a 'fictitious' or 'pseudo' force) directed away from the axis of rotation that appears to act on all objects when viewed in a rotating reference frame.

In physics, the Coriolis force is an inertial force (also called a fictitious force) that acts on objects that are in motion relative to a rotating reference frame.

In astronomy, the rotation period of a celestial object is the time that it takes to complete one revolution around its axis of rotation relative to the background stars.

A rotation is a circular movement of an object around a center (or point) of rotation .

In physics, circular motion is a movement of an object along the circumference of a circle or rotation along a circular path.

Stellar rotation is the angular motion of a star about its axis.

Rotation around a fixed axis is a special case of rotational motion.

A centripetal force (from Latin centrum, "center" and petere, "to seek") is a force that makes a body follow a curved path.

In physics, the concept of absolute rotation—rotation independent of any external reference—is a topic of debate about relativity, cosmology, and the nature of physical laws.

In physics, relativistic angular momentum refers to the mathematical formalisms and physical concepts that define angular momentum in special relativity (SR) and general relativity (GR).

The rigid rotor is a mechanical model that is used to explain rotating systems.

This article describes a particle in planar motion when observed from non-inertial reference frames.

In geometry, various formalisms exist to express a rotation in three dimensions as a mathematical transformation.
