PHYS 201: Principles of Physics I-Section 1

• Measurements and Standards
•  video  - Grains of Rice

• I would like to have the PASCO 2-m track, motion detector, motion cart, fan for motion cart, block of wood to tilt track up. I want the motion detector to be on the left side of the track as the students see it. I will need the computer set up to see the motion. I also want a tennis or racquet ball.

• I would like the scooter and cart to stand on while I push across the lecture hall. I also want the air track (not the PASCO system) with the fan car and regular carts of different masses. I need the fan cart to push at least two carts of different mass.

•  video  - Hanging Masses
• Weighing
  ( I would like to hang 1 kg and 2 kg masses on the spring scale in order to demonstrate how we calibrate forces.)

• I need the two carts that you can stand or sit on. I would like a heavy bag that two students can toss between them. I need two force probes with the PASCO system to show Newton's third law. I don't think I need the 2-m track. I do need the devices that go on the end of the force probes: hooks and rubber, rubber band between them.

•  video  - Bottle and Pencil
• Weighing
• Air Track Reaction Cars
  (I did not get to do the demo last time that used the fan car on the airtrack that could push at least two carts. I want to show the change of acceleration by the same force (the air car). So I need this again. )
•  video  - Newton's Sailboat
• Distortion Loops

• I want to demonstrate static and kinetic friction using the PASCO force probe, two - 1/2 kg masses to fit into the force probe and two boards with different frictional surfaces. I would also like a spring placed horizontally on the table with one end connected to a fixed vertical rod and the other end free so I can pull on it to show F = -kx.

• I need a rope or string with a ball at the end, so I can swing it around over my head to demonstrate circular motion.

• Force and Tension

• The is the work done by a compressed spring version in PASCO. I want to do Lab 8 in PHYS142W. I have done this the last two years. I believe it is activities 2-2 and 3-1: Work done by a compressed spring and work-energy principle. Let's put in mass of cart and bar masses to make it agree.

• Potential Energy
  ( I would also like a simple, empty shipping box that I can easily hold up and drop on the floor.)
•  video  - Conservative System
•  video  - Loop - the - Loop

• I need a bean bag and a ball like a racquetball. I need to show that one bounces (recoils) when I drop it, but the other doesn't. I also need the two carts that students can sit on and pass a ball between them. I need the heavy medicine ball. And I need the famous rocket bicycle.

• I would like a long rope that I can use to produce waves. I want to be able to change the tension of the rope, so it needs to be attached at one end. I will do this on the floor in room 203. Is it possible to have two ropes - heavy and light - so I can see if the wave velocity depends on the density?

• I want to show waveforms of a tuning fork on an oscilloscope displayed on TV. So I need tuning forks, microphone, oscilloscope, etc. I also need a coke bottle with some water in it to blow on.

• I want the toilet paper gun so I can shoot toilet paper out over the room. I would also like the leaf blower and large beach ball. I want the device to throw curve balls. I want the atomizer. I want the device with several different holes at various heights to show the water coming out has different speeds and trajectories.

• I need three styrofoam cups. One with hot water, one with cold, and one with room temperature water. I also need a collection of various kinds of thermometers.

• LN2 - Thermal Effects on Solids and Gases

• I need two large (not small) styrofoam cups each about half full (with precisely the sam amount) of room temperature water. I need a piece of copper and aluminum metal of precisely the same size in boiling water with tongs so I can drop them in the cups of water. I need a PASCO thermometer in each cup with the DataStudio system so I can measure the temperature. I will supply the aluminum and copper pieces.
