Don Ion made several useful animations for teaching physics classes. He used Flash starting back in the days when Flash was not an Adobe product but was a Macromedia product. His animations included interactivitiy; people could control the action using the controls included with the animations. People could use eithe rFlash or Gnash to play and control the animations.
Unfortunately the SBCC administration is heading in the direction of not allowing Flash on the campus. Thus, the animations have been converted to the videos you can download from this web page. The interactivity is lost in the conversion. However, the lessons taught by the animations are still presented by the video versions. Students and instructors can use pause, rewind and fast-forward features of their video players to control the action.
At the time this web page was posted, you could still access the old Flash files here
