"Web7 Mar 2007 · sirdoug007. The way you tell whether a system (such as a car's suspension) is under or overdamped (or "critically damped" which means the perfect amount of damping) is by looking at how it oscillates. Damping absorbs and dissipates the energy put into the suspension (in the form of heat) to control oscillations. " - Under over and critical damping
