  • Measuring Static Friction
    Demonstration using a wooden ramp of the dependence of μs on surface, but not surface area or mass.
  • Pulley/Plane Demo
    Demonstration of pulley/plane system; additional mass hangs, then falls; explanation of changing friction.
  • Waterplaning and Air Tracks
    Explanation of how friction can be eliminated by hydroplaning and air tracks, with brief demonstrations.
  • CO2 Shuttle
    Video of a device that travels on cushion of CO2 on plate glass; the friction is so low a flea can pull a large book on the device.
