Mit Physics Demo -- The Wimshurst Machine

A Wimshurst electrostatic generator - en.wikipedia.org/wiki/Wimshurst_machine - , working on the principle of induction, generates high voltage differences and sparks between two movable electrodes. By increasing the distance between the electrodes, higher potential differences can be built up. Electrostatic induction - en.wikipedia.org/wiki/Electrostatic_induction - refers to the principle that charges in an object (especially a conductor) redistribute themselves in the presence of nearby charges. Opposite charges are attracted to each other, while ...

Mit Physics Demo -- Potential Energy To Kinetic Energy

Two identical metal balls are dropped from the same height using an electromagnetic release. One ball is dropped freely, while the other hangs from a string, acting as a simple pendulum. Using two photogates, we see that the vertical velocity of the dropped ball is identical to the horizontal velocity of the pendulum, measured at the same height. Potential energy has been converted to kinetic energy equally in both cases. Watch the original video on MIT TechTV - techtv.mit....

Mit Physics Demo -- Fire Extinguisher On A Tricycle

A CO2 fire extinguisher is mounted on the back of a tricycle. When the CO2 is released, the tricycle is propelled forward. Watch Professor Lewin perform this demonstration on the Martha Stewart Show: www.marthastewart.com/show/the-martha-stewart-show/teacher-appreciation-day?lnc=4ef2dc5bfca40110VgnVCM1000003d370a0aRCRD&rsc=showarchive_tv_show-archive See the original video on MIT TechTV - techtv.mit.edu/videos/1067-fire-extinguisher-on-a-tricycle

Mit Physics Demo -- Push Me, Pull You

Two carts are connected together on an air track with a spring. Under bright lights you can see the coupled oscillation of the carts back and forth, but under black lights you can see that the center of mass moves at a constant velocity. See the original video on MIT TechTV - techtv.mit.edu/videos/674-push-me-pull-you

Mit Physics Demo -- Center Of Mass Trajectory

Odd-shaped objects with their centers of mass marked by orange paint are thrown. While the objects appear to follow very wobbly trajectories when viewed under bright lights, under black lights you can see that their centers of mass travel in smooth parabolas. Then center of mass is not necessarily in the center of an object, as demonstrated by the last object in the video (a weighted disk). See the original video on MIT TechTV - techtv.mit.edu/videos/773-center-of-mass-trajectory

Mit Physics Demo -- Spray Paint Oscillator

A can of spray paint is attached to a spring oscillator. A roll of paper is run past the oscillating can. The result is a sine wave - en.wikipedia.org/wiki/Sine_wave - on the paper. Watch the original video on MIT TechTV - techtv.mit.edu/videos/803-spray-paint-oscillator
