PHYS 1425-005: Physics 1 for Engineers

• a basketball and a pingpong ball (for free fall demo) and a meter stick

•  video  - Range Gun
  (set ball launch and blue bucket opening heights equal, and show 1-click power with 30 or 60 degrees has the ball land in the same spot, whereas at 45 degree the ball overshoots. )

•  video  - Ballistics Cart
  (Just flat track)

•  video  - Pendulum with Moveable Peg

• center of mass styrofoam with lights 2

•  video  - Pendulum with Moveable Peg
  (One more time!)

• bicycle wheel on a stand, so I can apply torque on the wheel with my hand

• Rotational Inertia Rods
  ( with a scale to show that the masses are the same )

• meter stick

•  video  - Rolling Objects and Moments of Inertia
•  video  - The Falling Rigid Body
•  video  - Vector Nature of Angular Momentum

•  video  - Center of Mass of Virginia

•  video  - Center of Mass of Virginia
  (For section 006 (3:30-4:45) only )
•  video  - Pascal's Vases
• Hydraulic Press
• Magdeburg Hemispheres
•  video  - Archimedes' Principle I
• Archimedes Principle III
  (Just Helium balloon and a jar, I don't need the trash bag demo)

•  video  - Venturi Tube
  (with the accompanying solitary u-tube with a plug on one-side with asymmetric level )

• SHM demos (1. Vertically set spring with varying weights (e.g 1kg and 250g) to show the period variation (ideally two identical springs to show the period variation at the same time) 2. Simple pendulums with different lengths to show that the period varies)

•  video  - Venturi Tube
  (together with the unlevel U-pipe with one end closed )

• 1. Helix coil with putty and crank on to show using overhead camera

  2. Slinky to show longitudinal wave

  3. The long spring (in lieu of a rope) to show tension dependency of the wave speed

•  video  - Standing Waves
  (No strobe needed )
•  video  - Doppler Buzzer
• Interference of Sound Waves
  (700Hz)
•  video  - Tuning Fork Beats
  (just two tuning forks and a putty )
• Sonometer
  (in my office (I'll bring it to class) )
•  video  - Air Driven Organ Pipe

• No demo (group exam)

• Absolute Zero
•  video  - Thermal Expansion
  (ball & ring, bi-metal strip and bunsen burner )
• LN2 - Thermal Effects on Solids and Gases
  (just balloons and LN2 )

•  video  - Boiling by Reducing Pressure

• Boiling Water in a Paper Cup

•  video  - Precession of Bicycle Wheel Under Gravity Force
