OverviewOrbital angular velocity of a point particle Spin angular velocity of a rigid body or reference frame See alsoExternal linksIn physics, angular velocity (symbol ω or , the lowercase Greek letter omega), also known as angular frequency vector, is a pseudovector representation of how the angular position or orientation of an object changes with time, i.e. how quickly an object rotates (spins or revolves) around an axis of rotation and how fast the axis itself changes direction. Common symbols: ω In SI base units: s−1 Derivations from other quantities: ω = dθ / dt SI unit: rad ⋅ s−1
