Show hintHide hint
Think of a pendulum swinging.
Question 2.
What is forced vibration?
Show hintHide hint
Consider what happens in an earthquake.
3Question 3.
What describes free vibration?
- Vibrations due to external forces

Show hintHide hint
Think about how a swing moves.
4Question 4.
True or False: Damping increases peak amplitudes during resonance.
- True
- False

Recall how damping affects oscillations.
Question 5.
Explain how you would model a damped harmonic oscillator. Include the parameters and forces involved.
Show hintHide hint
Focus on how each part of the equation relates to physical properties.
Question 6.
