Stable systems tend to oscillate at their natural frequency. This natural frequency depends on the strength of the restoring force and the inertia of the oscillating system. In this investigation, you will measure the natural frequency of a spring and mass system and determine the effect of the frequency of a periodic force on the resulting amplitude. Resonance occurs when a periodic force is applied at the natural frequency of a system and results in an increase in the amplitude of the oscillation.
