Angular Momentum of Bird Question

  1. Jun 26, 2011 #1
    A bird flies in a straight line directly over a field. Does the bird have angular momentum with respect to a man standing in the field?

    Yes.

    Does the man have angular momentum around the bird?

    Yes.

    Do they have *net* angular momentum around their common center of mass?

    No.[EDIT] More precisely, the net angular momentum is zero if you consider the man-bird-field system to be closed, and ignore the gravitational attraction between the man and bird.

    Why?

    Because angular momentum is conserved.

    Now I have a question? Why was this posted to the Quantum Mechanics forum?
