Abstract Title: Example Harmonic and Anharmonic Oscillators Demonstrated and Analyzed
Abstract: A commercially available teaching apparatus was easily modified to show the behavior of a spring oscillator and a magnetic hardening oscillator.  That apparatus will be demonstrated with position (time) data collected and graphed.  Simple approximate fits reveal the character of their dissipations in addition to the anharmonic oscillator's expected period variation and transition to harmonicity.  The latter is especially obvious when phase plotted.  The oscillators are then numerically modeled using a simple leapfrog algorithm.  The appropriate force laws are found using a force sensor.
