Damping is an influence within or upon an oscillatory system that has the effect of reducing or preventing its oscillation. 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 … Ver mais Depending on the amount of damping present, a system exhibits different oscillatory behaviors and speeds. • Where the spring–mass system is completely lossless, the mass would oscillate indefinitely, … Ver mais The damping ratio is a parameter, usually denoted by ζ (Greek letter zeta), that characterizes the frequency response of a second-order ordinary differential equation. It is particularly … Ver mais The Q factor, damping ratio ζ, and exponential decay rate α are related such that Ver mais Viscous Drag When an object is falling through the air, the only force opposing its freefall is air resistance.
