Homework Help: Spinning on chair

  1. Mar 16, 2005 #1
    Why is it that when I hold a spinning wheel on a rotating platform, when I turn the wheel upside down, the platform rotates?

    Is it because the angular momentum changed dircetions? Hence applying a force to keep sability making the platform turn?

    Is this the same idea is a top? How it is easier to keep a top on the tip when it's in motion rather than when it is stationary?
