{{Classical mechanics|rotational}}

A '''rotating frame of reference''' is a special case of a [[non-inertial reference frame]] that is [[rotation|rotating]] relative to an [[inertial reference frame]]. An everyday example of a rotating reference frame is the surface of the [[Earth]]. (This article considers only frames rotating about a fixed axis. For more general rotations, see [[Euler angles#Vehicles and moving frames|Euler angles]].)
