These sites are amazing. They teach solid physics but
include the dirty and messy parts of the real world that
make the topics more interesting.

I really like that UNSW music site. There's lots of good
physics there.

Check out the Physics of
Racing (Cars) at <http://phors.locost7.info/contents.htm>

I'm not sure I like that site so much. It starts with an
uncompromising, unenlightened, and IMHO incorrect assertion
that there is no such thing as centrifugal force. The fact
is that race-car drivers experience centrifugal fields all
the time.

For a discussion of centrifugal fields in particular and
rotating frames in general, see

It seems inconsistent for us to teach students about the
importance of Einstein's equivalence principle and then
get all huffy when they apply it to Practical Physics
situations such as a car.
