WebLaw of Conservation of Angular Momentum. The angular momentum of a system of particles around a point in a fixed inertial reference frame is conserved if there is no net external torque around that point: d→L dt = 0 d L → d t = 0. or. →L = →l 1 +→l 2+⋯+→l N = constant. L → = l → 1 + l → 2 + ⋯ + l → N = constant. http://www.hunter.cuny.edu/physics/courses/physics110/repository/files/Exam%20Review%20Problems%20answers.pdf
