In quantum mechanics, the square of the operator corresponding to this quantity commutes with the Hamiltonian if the potential is central.
In quantum mechanics, the square of the operator corresponding to this quantity commutes with the Hamiltonian if the potential is central. Kepler's Second Law arises from the fact that areal velocity is equal to this quantity divided by twice the mass of the orbiting body, and the (*) orbital form of this quantity is quantized in units of the reduced Planck's constant. Noether's Theorem applied to rotational invariance yields the conservation of this quantity, and its intrinsic form is called spin. This quantity is equal to the moment of inertia times the angular velocity. For 10 points, name this physical quantity, the rotational counterpart of momentum.
