IEVref: 113-03-22 ID: Language: en Status: Standard Term: angular momentum Synonym1: moment of momentum [Preferred] Synonym2: Synonym3: Symbol: L Definition: for a material point and a given origin point, axial vector quantity equal to the vector product of the position vector r and the momentum p, thus L = r × pNOTE 1 For a continuous body, angular momentum is equal to the integral L = ∫ r × v dm = ∫ (r × v)ρ dV, where ρ is the mass density in an domain having quasi-infinitesimal mass dm and volume dV, position vector r, and velocity v. For a system of particles, it is equal to the sum of their angular momentums. NOTE 2 A body with moment of inertia Jz with respect to an axis z and rotating with angular velocity ωz round that axis has angular momentum Lz = Jzωz. NOTE 3 The coherent SI unit of angular momentum is kilogram metre squared per second, kg·m2/s. Publication date: 2011-04 Source: Replaces: Internal notes: 2014-07-07: Symbol L corrected to L.
