PURPOSE: To illustrate the behavior of a driven and damped oscillator.
DESCRIPTION: A moveable glider, attached by stretched strings to a fixed glider at the left and an oscillator motor at the right, executes SHM when displaced and released. The oscillator can be driven by the variable frequency motor driver and damped by eddy currents by placing a magnet close to the base of the moving glider. The natural frequency of the glider can be changed by adding mass to the glider or by increasing the spring tension.
SUGGESTIONS:
EQUIPMENT: Drive motor, gliders, springs, damping magnet on stand, weight set, double sided tape, and air track.
SETUP TIME: 10 min.
