Damping

Graph of a damped vibratory deflection y.

Damped spring.

In physics, damping is any effect that tends to reduce the amplitude of vibrations.

In mechanics, the internal friction may be one of the causes of such damping effect. For many purposes the damping force F_f can be modeled as being proportional to the velocity v of the object:

$F_{\mathrm{f}}=-cv,$

where c is the damping coefficient, given in units of Newton-seconds per meter.
