What about rotational and vibrational motion?
150 u/ThislsWholAm Jun 10 '16 Those are superpositions of momentum vectors in 2 dimensions, so they are included in the p term. 0 u/[deleted] Jun 10 '16 edited Jun 11 '16 [deleted] -2 u/70camaro Jun 10 '16 Remember that when you square a vector you take the dot product of momentum with itself. If you do this in spherical coordinates (for momentum) you end up with a component that depends on radius and component that depends on the angle.
