The commutator of the x and y operators associated with this quantity is i h-bar times the z operator associated with this quantity. This quantity is quantized in units of h-b
The commutator of the x and y operators associated with this quantity is i h-bar times the z operator associated with this quantity. This quantity is quantized in units of h-bar, and its conservation leads to an orbiting body increasing its velocity when closer to the body it is orbiting, the result seen in Kepler's second law. The time derivative of this quantity is torque, and this quantity is conserved when there is no external torque acting on the system. For 10 points, name this quantity symbolized L, which is equal to the product of moment of inertia and angular frequency and serves as the rotational analog of linear momentum.
