The value of video analysis in physics education is well established. The video
format is familiar to students, contains a wealth of spatial and temporal data (builtin clock), and provides a bridge between direct observations and abstract representations of many physical phenomena. Tracking the positions and colors of features in a video image, and then transforming the resulting data into real-world
values and graphical overlays, offers many possibilities for building and testing
physical models both conceptually and analytically.
Moreover, there are effective and interactive educ
