Question by Casey: Where is a good site to learn AP Physics C for free online?
I am interested in the subject and I never was able to take it in high school as my school did not offer that particular AP course. I want to get a start before college starts.
Answer by oldprof
I did my physics post grad work at a brick and mortar school, but I’ve read and heard that Kahn Academy is an excellent online source for learning physics at several levels of education. [See source.] They advertise “free world-class education” so they are worth some investigation.
