### 標題

• Resonance
• Harmonic Motion
• Oscillator

### 描述

Amber Chang (2011)

### 學習目標

• Explain the conditions required for resonance.
• Identify/explain the variables that affect the natural frequency of a mass-spring system.
• Explain the distinction between the driving frequency and natural frequency of a resonator.
• Explain the distinction between transient and steady-state behavior in a driven system.
• Identify which variables affect the duration of the transient behavior.
• Recognize the phase relationship between the driving frequency and the natural frequency, especially how the phase is different above and below resonance.
• Give examples the application of real-world systems to which the understanding of resonance should be applied and explain why.
