Friction and Heat -- The Science of Speed
From nsf.gov, produced by National Science Foundation
This 5:25 long video shows how friction always creates heat in race cars.  Brakes and tires depend on friction to work, but more friction isn't always better. In the engine, friction is never good and engine builders use everything from oil to high-tech coatings to get a little extra horsepower. A good lesson to show students how friction impact their life.
