Some VPython Demonstrations

The following are some VPython mechanics demonstration programs. VPython is nothing more than regular Python with an extra module called visual. You need to have VPython (Python+visual) installed in your system to run these demos; if you don't, you can get it free of charge at http://www.vpython.org/. These demos work with Python versions 2.5-2.7. I have not tested them with Python 3.0, but they may also work with this version after only minor changes, if any.
To download a demo, right click the item and select
the option "Save Target As...".
If you are using Windows, you may want to change the extension of the file
from .py to .pyw; this will allow you to click the file without triggering
the opening a DOS window.
