Is L always changing?

  1. Oct 23, 2003 #1
    I always say that L is processing around Lz, never line up with Lz, so is that means L is always change its direction and so L vector is changing? So what force is changing it?

    In order for questions to get answered, they have to have some minimum level of clarity. At least tell us what you have in mind for "L" and "Lz".

    To me, L mean angular monmentum, which is R X P, R is position vector, P is momentum vector.
    Lz is the direction which L is processing around.

    It is not clear to me what motion is being described? Is something going around in a circle or is it something else?
