Damping ratio, abbreviated as \(\zeta\), a dimensionless number, describes how oscillations in a system decay after a disturbance. It describe the behavior of a damped dynamic system, such as a vibrating mechanical or electrical system. It quantifies the relative amount of damping present in the system's response to external forces or disturbances.

Damping Ratio Interpretation
Damping in systems is important to control oscillations, absorb energy, and stabilize the behavior of mechanical, electrical, and control systems. The damping ratio is a key parameter in understanding and designing the dynamic response of such systems.
