So, the AP test for Physics C is soon (Im not taking the test... dont have any intention of skipping any physics classes in college), and that means that theres pretty much no more work. I mean, we're going to be doing some relativity and (crosses fingers) some quantum, but the big thing is projects! Now this my teacher's first year teaching this class, so she doesnt have too many suggestions. Basically, we need to build something, or do some sort of project, related to E&M. Im thinking an E&M version of a Rube-Goldberg device. Or maybe a Gauss rifle (yes, she'd actually let us build one). Of course, I could just go the ol' bass pickup route, but that seems like it might more engineering than physics. Any ideas? It has to relate to E&M. Complicated projects are no good, considering we only have a month to do them.
