WebDamping coefficient is a material property that measures the ability to absorb energy from a system after loading. For example, a basketball has a low coefficient because it bounces back, rather than absorbing energy. …
WebFeb 15, 2024 · Since the actual damping coefficient is 1 Ns/m, the damping ratio = (1/63.2), which is much less than 1. So the system is underdamped and will oscillate back and forth before coming to rest.

In physical systems, damping is produced by processes that dissipate the energy stored in the oscillation. Examples include viscous drag (a liquid's viscosity can hinder an oscillatory system, causing it to slow down; see viscous damping) in mechanical systems, resistance in electronic oscillators, and absorption and scattering of light in optical oscillators.
