Von Braun rotating space station

  1. Nov 22, 2014 #1
    So I've been thinking about the Von Braun rotating space station model lately and I was curious about a few things. First, if someone dropped a ball in one (the ship is spinning so the centripetal force is equal to the persons weight on Earth so it creates an artificial acceleration of gravity of -9.8 m/s^2), would it fall straight to their feet accelerating at -9.8 m/s^2 relative to the person or would it do something else.
    Also, if there are uninformed people/masses in the ship, will they slow the rotation down if there isn't a constant thrust or will angular momentum keep it spinning?

    A ball dropped by a person standing on the floor of a rotating space station would fall mostly straight to the person's feet but would be deflected slightly anti-spinward by Coriolis acceleration.

    The state of intellectual enlightenment of the people and masses on the ship has no effect on space station physics, unlike cartoon physics. The station will keep spinning even without constant thrust.
