G2-09: FORCED HARMONIC MOTION WITH SONAR

ID Code: G2-09
Purpose: Plot a graph of forced damped harmonic motion near the resonant frequency.
Description: A Macintosh computer with Universal Laboratory Interface and an ultrasonic range finder is used to plot the motion of a large mass on a spring driven near its resonant frequency. With a large amount of damping, the result is a change in the amplitude of the oscillation, as shown in the photograph above.
