• AP Physics 1: Forces 27: Tangential Acceleration and Centripetal (or Radial) Acceleration
• The hilly road problem can be found in AP Physics 1: Forces 25: Circular Motion 7: Car on Hilly Road.
• AP Physics 1: Forces 28: Inertial and Non-Inertial Reference Frames and Coriolis Effect
• If you wish to review the discussion on centrifugal force and the letting go of a rock on spinning merry-go-round, it can be found at 12:51 in AP Physics 1: Forces 19: Circular Motion 1: Centripetal Acceleration and Centripetal/Centrifugal Force.
• For Coriolis effect: ball throwing on spinning merry-go-round demo: Coriolis Effect http://www.youtube.com/watch?v=dt_XJp77-mk. There is also a simulation and a lot of interesting information on Wikipedia: http://en.wikipedia.org/wiki/Coriolis_effect .

AP Physics 1: Forces 29: Newton’s Law of Gravitation and Cavendish’s Measurement of G

A short video about Cavendish and his famous Cavendish experiment: The Cavendish Experiment - Sixty Symbols at http://www.youtube.com/watch?v=2PdiUoKa9Nw

I also enjoyed listening to the book A Short History of Nearly Everything by Bill Bryson. It is basically on science history. Bryson is not a scientist, but I think he did a great job on the book. Don’t be too picky about every science term/event being used exactly correctly, although there is an Errata and Corrigenda page for this book at http://errata.wikidot.com/0767908171 if you are interested. I can’t seem to find time to sit down to read books, so I listen to them when I do housework or do work in the yard : ) A Short History of Nearly Everything kept me engaged when I cleaned and painted all the windows in my house a couple years ago.
