PHYS 1060-001: How Things Work

• Hi Al, Here we go again. Collection of balls such as bowling ball, tennis ball, super ball, etc./ razor scooter I never used it but I'd like to try. 1 can of empty coke 1 full can of coke Thanks Richard

• One or two extra large blocks for showing support force and Large bowling ball again for show

•  video  - Inclined Plane
  (Include cart and masses and scale.)

• Tennis racquet and ball, Bloomfield mini-me, baseball bat center of percussion apparatus, bowling pin that I can throw in the air, some type of seesaw apparatus. See you at noon.

•  video  - Inclined Plane
• Human Lever Arm
• Rotational Inertia Rods

• Center of mass toys, Newtons cradle, air hockey pucks,large mass in wagon with scale to pull it I need one without wheels to drag it and one with wheels, I also need pencils to put wagon without wheels on pencil to pull it, I want to show real ball bearings as an example, bean bag and super ball to drop and compare, a bicycle wheel with ball bearing just to show and spin.

• Teflon rods, silk and spinner, UVa electroscope, •Two spherical conductors on an insulating pedestal •Van de Graaff Generator with needle to explain Corona Discharge •Parallel Plate Capacitor to show that the voltage increases when moving the plates apart •Faraday cage showing charge inside metal cup is 0. Radio inside cage too.

• Teflon rods, silk and spinner, UVa electroscope, •Two spherical conductors on an insulating pedestal •Van de Graaff Generator with fluorescent lamp and cage to demonstrate Faraday cage again •Parallel Plate Capacitor to show that the voltage increases when moving the plates apart again. Focus on capacitor as a battery this time •Faraday cage showing charge inside metal cup is 0. •I’ll bring in two lemons to make a lemon battery. I’ll need the zinc and ?? plates and put two lemons in series. •KiloWatt meter

• Hi Al, I want to show that a wire with current flowing through it produces a magnetic field. What do you suggest. I can use a fat wire with a battery and compass to show the presence of the magnetic field. I'll try to get in around 11:30 to 11:45 to test it. Would liquid nitrogen help to lower resistance of the wire and increase the current to see a strong effect. I have done this before without cooling with 3-4 volts and a compass and a normal wire.

• An old oscilloscope to show 120 Volt ac signal on the screen? Three 100 watt AC bulb and cord to plug in wall socket to demonstrate ac and a meter - parallel circuit, Red and green LED coil with large grey magnet, Back EMF in an Inductor and Induction Coil, Jumping ring demo– Just for fun

• HI Al Today we need some toys. Tough subject matter. 1) Theremin would be nice to illustrate, 2) Also a small charged capacitor and resistor discharging slowly through a red LED in say 10 seconds or so. Time is not critical. 3) The strong neodymium alloyed magnet

• One long spring 10 feet or so. I want to move it up and down with my hands to show standing waves. One end must be tied to a clamp. Sorry once again to be so late. Thanks Richard
