IEVref: 113-01-41 ID: Language: en Status: Standard Term: angular velocity Synonym1: Synonym2: Synonym3: Symbol: ω Definition: axial vector quantity describing the rotation around an axis, with magnitude $\omega =|d\phi /dt|$, where $d\phi$ is the plane angle change during the infinitesimal time interval with duration dt, and with direction along the axis for which the rotation is clockwiseNOTE 1 In an inertial frame, the angular velocity does not depend on the chosen coordinate system provided that the orientation of space is kept (either right-handed or left-handed). NOTE 2 The coherent SI unit of angular velocity is radian per second, rad/s.
