| Viscous Dumping | Coulomb Dumping |
|---|---|
| In case of viscous damping, the ratio of the two successive amplitudes is constant. | In case of coulomb damping, the difference between any two successive amplitudes is constant. |
| Viscous dampening is caused by energy losses in liquid lubrication between moving parts. | Coulomb dampening is caused by friction between rubbing surfaces that are dry or don't have any lubrication. |
| Viscous damping force is proportional to the velocity. | Coulomb's damping force is independent of velocity but depends on the co efficient of friction. |
| Viscous dampening is applied for both liquids and solids. | Coulomb damping is applied only for solids. |
| In case of viscous damping, liquid observes energy so energy dissipation takes place. | In case of coulomb damping, energy dissipates because of friction between two solid surfaces. |
