PHYS 1420-001: Intro Physics 1 - Majors

•  video  - Standards of Measurement

• PASCO aluminum track with Motion Detector II to measure position, velocity and acceleration of rolling cart along track in horizontal and inclined orientations. Impluse push cart along flat track which comes to a sudden stop at far end or impulse push cart up inclined track such that it barely reaches top and then rolls back down on its own only to be suddenly stopped by hand at bottom.

• Projectile Motion II

• Weighing
  ( I actually want a spring scale, and two weights (one heavy, one light))

• Push Me Pull Me Carts
• Distortion Loops

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

•  video  - Marble and Feather

• Work Done by a Compressed Spring

•  video  - Pendulum with Moveable Peg
  ( This is assuming I am not going online. Will let you know.)

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

•  video  - Air Track Collisions

•  video  - Rolling Objects and Moments of Inertia
•  video  - The Falling Rigid Body

•  video  - Vector Nature of Angular Momentum

• 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.)

•  video  - Pascal's Vases
• Magdeburg Hemispheres
• Cartesian Diver

•  video  - Pascal's Vases
• Magdeburg Hemispheres
• Cartesian Diver
•  video  - Venturi Tube

• Projected Uniform Circular Motion

• BOSS model for buildings in earthquake (resonance frequency)

• Damped Mass on Spring
•  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.)

•  video  - Transverse Waves
  (You had a version of this demo where you connected two torsion systems)

• Do you have the possibility to show the frequency composition of different sounds (lecturer singing, guitar, pipe)? Dinko is giving that class. In 2023, I installed a RTM analyzer on my laptop, and I had gotten a set of tuning forks, and an instrument from somewhere.

•  video  - Tuning Fork Beats
  (The tuning forks, not the electronic version )
• Open / Closed Resonance Tube
•  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. )

• LN2 - Thermal Effects on Solids and Gases
  ( Only bimetal strip and burner. I forgot to show this on Wednesday.)

•  video  - Boiling by Cooling
•  video  - Brownian Motion
•  video  - Kinetic Theory

• Do we have any demo on diffusion?

• Heat Capacity using Wax and metal Balls

•  video  - Fire Syringe
• Jug O' Air

•  video  - Thermal Conductivity
•  video  - Light The Match
