If you combine the advice of Diez B. Roggish and Paul McGuire:
Download and install VPython.
Download and install PyODE.
Get and run VPython Contributed program:
    http://www.vpython.org/contributed/visualjoints.py
which shows a weight on a hinge with another attached to the ball;
quite believable dynamics.  Although the code is really not
carefully written, looking at it may give you a sense of how
little work you'll have to do to get some physics action going.
