•  video  - Uniform Linear Acceleration - Time
•  video  - Uniform Linear Acceleration - Velocity

•  video  - Uniform Linear Acceleration - Time
  (Have four equidistant gates separated by 0.5m, measure time between gates and instantaneous velocity at each gate for two cases: 1) flat track 2) inclined track (raise one end 10cm). )

•  video  - Marble and Feather
•  video  - Free Fall Acceleration

•  video  - Free Fall Acceleration
  (might try this again, since it got tangled last time)
•  video  - Shoot and Drop
  (set at height = 1.5m, with coffee can at length = 1.5m, the distance from start of projectile to far edge of can)

• PASCO cart and ball for student to demonstrate "relativity cart" phenomenon

• Brachistochrone curve

• A very long rope that two students can use to play tug of war. A second rope that I can attach to a scale and attach the scale to the first rope so I can measure how much force is required to pul it sideways. See you at about 8:15 to 8:25.

• Midterm Exam, no demos

• Hi Al, I would like the inclined plane with a block of wood. and also one large block of wood to use as a prop. I also would like to pull an object with a string angled upwards.

• Hi Al, I would like a spring and a 0.5 kg mass that I can use to stretch the spring and compress it. A soft spring constant would be fine. I want to lay it along the table and illustrate. I will not show simple harmonic motion. See you at 8:15 I hope. Richard

•  video  - Air Track Collisions
  ( Only need track and carts carts of same mass carts with one larger than the other two carts that stick together of same mass)
•  video  - Battering Ram Collisions

• Hi Al, I would like the bicycle wheel on axle with a clamp mounting it to the desk soI can use it as a prop and to be able to turn it. Also fork and spoon match stgick and glass for cm show and tell

•  video  - Battering Ram Collisions

• Al, Do we have anything to demonstrate torque? For example, a tight bolt and a wrench with a short lever arm compared to the same bolt with a wrench with a long lever arm. Show how much easier to turn bolt with long level arm. Also I would like to use the bicycle wheel again as a prop. No need to mount it.
