Damped Vibration vs. Undamped Vibration — What's the Difference?
By Tayyaba Rehman — Published on January 2, 2024
Damped Vibration involves gradual energy loss, reducing amplitude over time. Undamped Vibration maintains constant amplitude, with no energy loss.

Key Differences
Characterized by decreasing amplitude due to energy dissipation. Undamped Vibration: Exhibits constant amplitude as there's no energy loss.
Involves external forces like friction or air resistance reducing motion. Undamped Vibration: Idealized form assuming no external forces are acting.
Real-world applications, like shock absorbers, use damping to reduce oscillations. Undamped Vibration: More theoretical, used in models where damping is ignored for simplicity.
Can be over, under, or critically damped, affecting the system's response. Undamped Vibration: Represents a system's natural frequency without external interference.
The system eventually comes to rest due to energy dissipation. Undamped Vibration: Without damping forces, the system would theoretically oscillate indefinitely.
