Question 1
What does the governing equation for forced oscillation represent?
- It describes free oscillation without external forces.
- It describes oscillation driven by external forces.
- It is irrelevant to physics.
💡 Hint: Consider the role of the external force in the equation.
Question 2
True or False: Resonance occurs when frequency of the external force matches the natural frequency of the system.
- True
- False
💡 Hint: Think about how tuning forks resonate.

Challenge Problems
Push your limits with challenges.
Question 1
A mass-spring system experiences forced oscillation with a damping ratio of 0.2. The mass is 5 kg, the spring constant is 500 N/m, and the external force is 100 N at a frequency of 2 Hz. Calculate the amplitude at steady-state.
💡 Hint: Start with finding the natural frequency and proceed to use the amplitude formula.
Question 2
What would happen to the amplitude if the external force frequency is increased significantly past the natural frequency of the system? Explain why.
💡 Hint: Think about how energy resonance changes with different driving frequencies.
