PHYS 101: Intro to Physics Concepts - I

• AirPro Hockey pucks
•  video  - Tablecloth Pull
•  video  - Bottle and Pencil
  (ALSO: cardboard cubic meter, three 1 kg masses to pass around, wood block to push across table, styrofoam ball and bowling ball )
• Frames of Reference

• Air Track Reaction Cars
  ((fan cart on Pasco track, please)ALSO: bathroom scale on top of lecture bench, with camera on readout. ALSO: baseball and bat, bowling ball on green baby scale, ball on string, medicine ball and one black rolling cart. )

• Falling Drops of Milk
• Centripetal Acceleration
  (Could we use the wireless camera on this?? )
•  video  - Shoot and Drop
  (ALSO: tennis ball, big LED timer, inverse-square demo with light source and translucent glass with grids, drop water cup with holes in sides to show weightlessness )
• The Mechanical Universe
  (side 1 )

•  video  - Center of Mass Toys
  (tricky styrofoam balls connected by wood rod, 3-story tower with camera on it )
• Egg in a Sheet
  (ALSO: big LED timer, spinning tray with cup of water )
• Reaction Cars
  (would like to do this with timers. ALSO: need two cars of same mass to collide elastically )
• Fire Extinguisher Rocket Cart

•  video  - Conservative System
  ( ALSO: small rolling cart (the one I tried was about 6 inches long and weighed 15 Newtons) on a ramp, with Newton scale. want to move cart through three different motions: steep (say 40 degrees) very steep (say 65 degrees) and vertical, and show that force times distance is the same for each. need a string or rod to mark a consistent final vertical height. )
• Reaction Cars
• Fire Extinguisher Rocket Cart

• Energy Conversion and Conservation
  (and solar car )
• Reaction Cars
  (with a start and stop gate for each car please )
•  video  - Transverse Waves
  (ALSO: Schnatterly's headphones with which microphone on right side goes to left ear and vice versa )
•  video  - Longitudinal Waves
• Bell in a Vacuum
  (ALSO: make sound and vary frequency from 20 - 20,000 Hz )

• Pressure Gauges
  (U-shaped tube with green liquid (manometer?). Want to show what happens when pressure on one side increases, maybe by attaching inflated balloon. ALSO: sphygmomanometer and stethoscope. )
•  video  - Transverse Waves
  (want to show reflections at interfaces, using wave machine I guess )

•  video  - Moment of Inertia Wheel
  (do not need hanging weights or timer. ALSO:lacrosse stick and ball. ALSO: Model of human forearm. Last year we used a 40 cm rod of mass 0.4 kg, a "hand" mass of 0.6 kg, and a string to simulate the bicep connected 10 cm from the pivot. This gave a "bicep" tension of about 36 Newtons. It doesn't have to be exactly the same this year. )

• Simple Machines
  (Simple lever (plank, fulcrum, weight). ALSO: simple pulley system in which weight is lifted half the distance that you pull the string (2:1 mechanical advantage). ALSO: Lou's chair lift. ALSO: hydraulic press with camera on it. )

• Potential Energy
  (ALSO: a bright laser and magnet, to show that light not deflected by magnet )
•  video  - Magnetic Deflection of an Electron Beam
  (prefer the tube in which electrons graze phosphor-coated plate. )
• Discharge Tubes
  (the one with the Iron Cross pattern )
•  video  - Emission Spectra
  (also X-ray tube for show and tell )
• The Films of Charles and Ray Eames: Pioneers of Visual Ideas

•  video  - Photoelectric Effect in Zinc
  (ALSO: Jacob's ladder )

•  video  - Transverse Waves
  (Just need a slinky to show transverse and longitudinal waves. ALSO: seismograph that Mike built last year. )
