Comment on half-integer quantum numbers for the total angular
... a linear momentum p, the orbital angular momentum is l = r × p. The trajectories of the photons in a Gauss beam are parallel to the beam axis, i.e.,p = (0, 0, p). This leads directly to lz = 0. To consider the photon trajectory in a helical beam we note that the trajectory may be conceived as the sa ...

MOMENTUM ! - Urbana School District #116
... In the first two sample problems, we dealt with a frictionless surface. We couldn’t simply conserve momentum if friction had been present because, as the proof on the last slide shows, there would be another force (friction) in addition to the contact forces. Friction wouldn’t cancel out, and it wou ...
