Recent advances in technology have made video capture and analysis1 in the introductory physics lab even more affordable and accessible. The purchase of a relatively inexpensive web camera is all you need if you already have a newer computer and Vernier's2 Logger Pro 3 software. In addition to Logger Pro 3, other video analysis tools such as Videopoint3 and Tracker,4 which is freely downloadable, by Doug Brown could also be used. I purchased Logitech's5 QuickCam Pro 4000 web camera for $99 after Rick Sorensen6 at Vernier Software and Technology recommended it for computers using a Windows platform. Once I had mounted the web camera on a mobile computer with Velcro and installed the software, I was ready to capture motion video and analyze it.
