PHYS 1420-001: Intro Physics 1 - Majors

•  video  - Standards of Measurement

•  video  - Marble and Feather

• Projectile Motion II

• Push Me Pull Me Carts
• Distortion Loops

•  video  - Spinning Tray
•  video  - Contact Area Independence of Friction
• Coefficient of Friction

• Weight Dependence of Friction
  (I will provide a new picture soon! Blue wood plank with 5kg/10kg masses and spring scale. Pull on plank with spring scale until it begins to move - note max force for static friction. Now slide plank by pulling with scale - note constant force for kinetic friction.)

• Work Done by a Compressed Spring

•  video  - Pendulum with Moveable Peg

•  video  - Work Done on a Cart
  (Can you bring the scale so that people can measure the weight? It should be possible without disconnecting from the string. )

• Egg in a Sheet
•  video  - 2-Liter Bottle Rocket

•  video  - 2-Liter Bottle Rocket
•  video  - Air Track Collisions

•  video  - The Falling Rigid Body

•  video  - Rolling Objects and Moments of Inertia
  ( I am most interested in part 1 and 2. I would be also interested in part 3, but the description says it is not working well, and if so, I don't. Do we have a "same object shape, different density?" )

•  video  - Vector Nature of Angular Momentum

•  video  - Pascal's Vases
• Magdeburg Hemispheres

• Cartesian Diver
•  video  - Venturi Tube
  ( Last year, the tube was less complicated than on the website. That would be fine, too, just tell me what I get.)

• Breaking Wire (Plasticity)
  ( I want to show stress vs. strain for elastic and plastic deformation. That is, I need that students can see the wire length. If all they can see is that the wire breaks at some point, the demo would not be very interesting. Last year, we did that ok.)
• Projected Uniform Circular Motion
• Damped Mass on Spring
  ( No damping on Monday, just use as a spring.)

• BOSS model for buildings in earthquake (resonance frequency)

• Damped Mass on Spring
  ( I had this for Monday. Now with damping.)
•  video  - Forced Oscillations

•  video  - Transverse Waves
  ( Just the long spring for Monday with which I can show longitudinal and transverse waves)
• Bell in a Vacuum

•  video  - Transverse Waves
  ( This time the upper setup that demonstrates the different properties at reflection from fixed and loose ends)
•  video  - Standing Waves
•  video  - Diffraction & Interference in Ripple Tank
  ( I would like to show (a) spherical wave, (b) plane wave, (c) interference of two spherical waves, (d) diffraction: plane wave moving around large obstacle.)

• Do you have the possibility to show the frequency composition of different sounds (lecturer singing, guitar, pipe)? This would be for Apr 8 (Dinko is giving that class). Last time, I installed a RTM analyzer on my laptop, and I had gotten an instrument from somewhere.

• Open / Closed Resonance Tube
  ( Can we try this this afternoon (Apr 2) or tomorrow afternoon (Apr 3)? I need to understand before I hand it over to Dinko.)
•  video  - Air Driven Organ Pipe

•  video  - Doppler Buzzer
•  video  - Tuning Fork Beats
•  video  - Air Driven Organ Pipe

•  video  - Thermal Expansion
  (What we did last year is different than described on the website. We had ball and ring, and we let the ball cool down with Ln2 to fit in the ring. )
• LN2 - Thermal Effects on Solids and Gases
  ( I had this last year. you said you gave me racket balls, balloons and fresh tree leaves.)

•  video  - Boiling by Reducing Pressure
•  video  - Brownian Motion
•  video  - Kinetic Theory

•  video  - Boiling by Cooling

• Heat Capacity using Wax and metal Balls
•  video  - Fire Syringe
