The behavior of harmonic oscillators is easily characterized. For example, many undergraduates encounter systems such as an oscillating mass which stretches and compresses a spring. In these harmonic systems, the restoring force on the oscillator is linear, and the period of oscillation does not change if the oscillation amplitude is changed. However, variations on these systems can easily be constructed to display anharmonic behavior. We have examined three different anharmonic systems, each with a different nonlinear restoring force, and analyzed the relationship between oscillation period and amplitude for each.
