## Damping

In physics, damping is an effect that reduces the amplitude of oscillations in an oscillatory system (except for mass-dominated systems where $omega/ omega_0 >$√2), particularly the harmonic oscillator. This effect is linearly related to the velocity of the oscillations. This restriction leads to a linear differential equation of motion, and a simple analytic solution.

In mechanics, damping may be realized using a dashpot. This device uses the viscous drag of a fluid, such as oil, to provide a resistance that is related linearly to velocity. The damping force Fc is expressed as follows:

$F_{mathrm c} = -c frac{dx}{dt} , ,$
