Forced Harmonic Motion and resonance

One last twist on simple harmonic motion occurs when an object is driven by some external oscillating force. We call the result forced harmonic motion, and there is one particular facet of such motion which is important.

• Very brief theory behind forced harmonic motion
• An example of resonance
• Resonance lies behind the destructive power of the human voice.
