PHYS 109/609: Galileo And Einstein

•  video  - Marble and Feather
• Falling Drops of Milk

• Simple Machines
  (just lever, wedge and compound pulley; also conic section model; )
•  video  - Archimedes' Principle I

•  video  - Ray Optics Kit
• Confocal Mirrors

•  video  - Ray Optics Kit

• Falling Ball
  (I would also like to do the Galileo experiment of rolling a ball down a grooved wooden track, using water flow to measure time. )
•  video  - Shoot and Drop
•  video  - Pendula, Spring and Simple
  (just two pendula, same length different mass )

• Falling Ball
•  video  - Shoot and Drop
•  video  - Pendula, Spring and Simple
  (just single pendulum w/ timer )

•  video  - Ballistics Cart
• Projectile Motion II
•  video  - The Monkey and the Hunter
•  video  - Range Gun

• Centripetal Acceleration
•  video  - Pascal's Vases
• Magdeburg Hemispheres
  (Mike, I would also like to have a Bunsen burner and a ring, to boil water in a Coke can and crush it; also a glass or two and some thin smooth cardboard--slips of oak tag will do, or 3x5 cards, as long as they are big enough to cover the mouth of the glass. In addition, do you have anything to illustrate scaling--for example ball bearings of different diameters? I recall there was once a demo of this sort where you balance 8 spheres against 1 that has twice the diameter. )

• Magdeburg Hemispheres
  (also air track w/ pulley and mass to pull cart )

• Centripetal Force

• Air Track Reaction Cars
  (Also rocket cart, please. )
•  video  - Newton's Sailboat
• Distortion Loops

• Cavendish Balance Model
•  video  - Light The Match
  (This one demonstrates that invisible rays can be focussed. )
•  video  - Light The Match
  (This one demonstrates the principle of the Newtonian telescope. )
•  video  - Interference and Diffraction
• Additive Color Mixing
• Rainbow

•  video  - Kinds of Charge and Charging
•  video  - Attraction and Repulsion Between Charged Objects
•  video  - Van de Graaff Generator
•  video  - Magnetic Fields w/ Iron Filings
  (Also I want to do the Oersted experiment -- wire & compass; And if I could have some bell wire, a big 1.5 V battery (with screw terminals) & a large iron nail I will make an electromagnet before their very eyes! )
•  video  - Magnetic Deflection of an Electron Beam
• Flash Bulb Coil
• Electric Motor

•  video  - Van de Graaff Generator
  ( I actually want the Wimshurst machine. The reason I didn't ask for it last time is it does not seem to be listed among the demos. )
•  video  - Forces Between Current Carrying Wires
  ( Once again I want the bell wire and the nail-- preferably a de-magnetized nail--and a battery, to make a simple electromagnet.)
• Flash Bulb Coil
  (I'd also like the triple coil + galvanometer, to show that how much voltage you get depends on how many turns of wire you get. Doesn't seem to be listed. )
• Electric Motor
  ( I'd also like the little motor-generator connected to the electrolytic capacitor, showing that energy goes in when you crank, and comes back out again turning the motor. Thanks for all the hard work.)
• Physics Spaceflight Series
  ( Basically what I want here is the one where they drop a hammer and a feather on the Moon.)

•  video  - Magnetic Deflection of an Electron Beam
• Flash Bulb Coil
  (Actually, I want the triple coil with galvanometer, not the flashbulb thingy. Also the materials to make an electromagnet (again!). Finally, the demo on why it is better to step up and step down voltage in a power distribution system. (I couldn't find it in the manual, but it's a good one!) )
• Measurement of the Speed of Light
• Frames of Reference
  (I'd like to actually see these two cassettes, please. Can I come in around 10 AM to see them? Thanks. --jvn )

•  video  - Polarization of Light
• Frames of Reference

•  video  - Photoelectric Effect in Zinc
• Frames of Reference
  (Could you tell me how long this sucker runs? E-mail me at jvn@virginia.edu if you know. Thanks. PS: don't forget something that goes "bang!" PPS: don't forget the Brownian motion. )

• Frames of Reference
  ( Please set the tape to about 13 minutes from the beginning--that is, the beginning of accelerated frames. Also I didn't get to show Brownian motion on Tuesday, so if we could have it again... Thanks. PS: I don't see either the black globe or the depressed membrane curved-space gravity demo listed in the manual. I would like them both. )
