2. Big Ideas
Key idea Resonance occurs when periodic driving transfers energy efficiently to an oscillator. The key evidence is a large amplitude response when the driving frequency is close to the natural frequency.
What Students Can Learn
- Identify the driving frequency and the system's natural response.
- Compare amplitude at different driving frequencies.
- Recognise damping as a factor that limits amplitude.
- Use graph or motion evidence rather than just saying vibration is present.
Guiding Question
Which driving frequency produces the largest response, and how does damping affect it?
3. Try the Investigation
Start Away from Resonance
Observe the response at a low or high driving frequency.
Sweep the Frequency
Change the driving frequency in steps and compare amplitude.
Locate the Peak
Find the frequency range with the largest steady response.
Test Damping
If damping is available, compare how the peak response changes.
4. Teacher Notes
Lesson Use
Use this to show that timing matters, not only force size. Resonance is about energy transfer at the right frequency.
Discussion Prompts
Ask: What is being driven? Which setting gives the largest amplitude? What happens when damping increases?
Teaching Moves
Make students record amplitude for several frequencies before naming the resonance condition.
