Question 1
What is the damping ratio?
- A measure of frequency
- A measure of how quickly oscillations decay
- A measure of velocity
💡 Hint: It's related to how quickly the system loses energy.
Question 2
True or False: In an over-damped system, the motion oscillates.
- True
- False
💡 Hint: Remember the definition of over-damped motion.

Challenge Problems
Push your limits with challenges.
Question 1
A 4 kg mass is attached to a spring with a spring constant of 16 N/m and a damping coefficient of 4 Ns/m. Determine if the system is under-damped, critically damped, or over-damped, and justify your answer.
💡 Hint: Use definitions, don't forget to calculate both \\( \\gamma \\) and \\( \\omega_0 \\).
Question 2
Design a critically damped system with a given mass of 5 kg and specify the required damping coefficient for a spring constant of 25 N/m.
💡 Hint: Use the relationship for critical damping where \\( b = 2m\\omega_0 \\) for a mass-spring system.
