A '''frame of reference''' is a particular [[perspective (visual)|perspective]] from which the [[universe]] is observed. Specifically, in [[physics]], it refers to a provided set of [[Coordinate axis|axes]] from which an [[observation|observer]] can measure the position and motion of all points in a system, as well as the [[orientation (geometry)|orientation]] of objects in it. | A '''frame of reference''' is a particular [[perspective (visual)|perspective]] from which the [[universe]] is observed.
