This value is quantized s
This value is quantized so that it must equal an integer times the reduced Planck constant. Its components do not commute, so they are complementary variables in Heisenberg's Uncertainty Principle. Its derivative with respect to time, which can be found using the product rule, gives one term equal to zero and the other equal to torque. This conserved quantity equals moment of inertia times angular velocity. Name this quantity equal to the cross product of position with linear momentum.
