Physics: Cinema Classics is a treasure trove of physics video clips depicting demos, animations, and representations of physics phenomena. Our school purchased the LaserDisc in the early 1990s and the DVD set a few years ago. I'd love to give P:CC an enthusiastic thumb's up, but he mechanics of the DVD operation leave much to be desired. Navigating through demos is a nightmare; I'd prefer to have each demo as a QuickTime (or equivalent) file.
In any case, one vignette from the P:CC's Disc 5: Conservation Laws is a 1968 Project Physics gem called called "Nails into Wood." It's the kind of simple but clever demo I can really sink my pedagogical teeth into.
After developing qualitative and quantitative video demo sheets to accompany the clips, I built expanded Keynote representations of the demo. We travel to the Moon and Jupiter, and use mathematical analysis and estimation along the way. I tinkered and fussed with the presos over the past couple of days and decided they were ready for prime time. So I froze them into interactive QuickTimes and posted them to The Book of Phyz on the Energy page.
