Simultaneous shadow projection of circular motion and an oscillating mass on a spring. We see that the vertical component of the circular motion is identical to that of the vertically oscillating mass. This simple harmonic motion can be mathematically modeled over time with sinusoidal functions.
The 8 cm diameter plastic ball is mounted near the edge of a 46 cm diameter disk and is driven by a Bodine Electric Co type NS1-33R speed reducer motor. The disk is cut from 1/8" thick masonite. The mass weighs 20 N, and was fortunately paired with a spring to match the speed of the motor. Illumination is provided by a Kodak slide projector.
Thanks for watching!
