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 computer and 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.
