Damping is the attenuation of vibrations or oscillations.
It is the opposite of normal damping (oscillation decreases), so in negative damping to get even bigger oscillation.
The amplitude of resonant oscillations can be reduced by damping.Light damping reduces oscillations slowly.Heavy damping reduces oscillations quickly.Critical damping stops the oscillation within one cycle.The graph above shows light damping.
critical damping is when the amount of damping is large enough for the system to return toequilibrium as fast as possible without performing oscillations. Hope thatHELPED

Geometric damping is also called radiation damping. It is defined as energy radiation into a surrounding medium. Damping is defined as energy dissipation property of structures and materials that are put through time-variable loading.
In the damping level the level view and vertical spindle are crossed together...
The larger the surface area, the larger the damping of an oscillation
the further the frequency from the resonant one, greater would be the damping effect, hence greater the sharpness the lowre is the damping effect
Damping torque can be provided by: (a) air friction damping (b) fluid friction damping (c) eddy current damping. In air friction damping, a light piston moves with a very small clearance in air chamber. The piston moves against pressure of air in air chamber. In fluid friction damping, light varies are attached to spindle of moving system. The movement of spindle is suppressed due to fluid friction, Eddy current damping is one of the most efficient method of damping. It is based on the principle that whenever a sheet of conducting but non magnetic material like copper or aluminum moves in magnetic field, eddy currents are induced.
The damping coefficient ς is a parameter which determines the behavior of the damped system
