Am I too late to help you? I can help you with prettymuch anything you may need through a high school course. (I had the best teacher EVER) "The Granddaddy Equations", a.k.a., the three old well known ones having to do with final/initial velocity and acceleration, Igor touched on them in the previous post, then there's centripital acceleration, forces (can help with friction problems, but am rusty), index of refraction stuff (apparent depth in liquids is really cool), the lensmaker equation, the lens-mirror equation, object/image position with lenses/mirrors, ray tracing, doppler effect equations for light and sound (yes, they're slightly different), interference patterns, etc. I don't want to write it all out unless it could help you, so if I'm not too late, tell me. If not, and assuming that you don't already know everything that I just mentioned, I can try to draw out diagrams, explain things, etc. School just got out for me, so I returned my textbook, but I remember mostly everything. (at least I think I do...
)
P.S. - I'm a physics nerd.
