Summary: Erik Thompson has kindly allowed us to host copies of his excellent 9-part series introducing physics using 3D with VPython. http://showmedo.com/videos/series?name=pythonThompsonVPythonSeries
Detail: Erik covers the physics of motion in the first four videos (1 hour of content). The next 5 videos (to be on-line in a week) show friction, springs, weights and the motion of a satellite. In total there is a whopping 3.5 hours of brilliant tutorial material.
About ShowMeDo.com: Free videos (we call them ShowMeDos) showing you how to do things. The videos are made by us and our users, for everyone. Over half of our content is for Python.
We'd love to have more contributions - would you share what you know?
