WebSolutions. ( 1) Overdamping occurs when the system loses more energy than it can replace, resulting in a decrease in amplitude over time. This type of damping is characterised by a slow return to equilibrium. Critical damping is when the system just barely returns to equilibrium and doesn't oscillate at all. 128.
