Thanks very much for the positive feedback on the Circular Motion
compilation article I posted the other day. And yes JD, centrifugal
force is generally handled very badly within this topic, either by
omission or by misconception.
Anyhow, a few days after posting that article I came across a video that
really belongs to that article (although I haven't inserted it yet). It
was a short behind-the-scenes video about Playland's Derby Racer, which
is a carousel for grownups. I GIF'd out the parts where staff embark on
this high-speed ride and annotated them (after watching them carefully
many times over!).
