... oscillations of SHM retain the same magnitude indefinitely. In real systems energy is lost from the system due to factors such as air resistance and friction in bearings and pivots, thus the amplitude of the SHM steadily decreases. This removal of energy is called damping. SHM in a system such as a ...

... The previous image shows a system that is underdamped – it goes through multiple oscillations before coming to rest. A critically damped system is one that relaxes back to the equilibrium position without oscillating and in minimum time; an overdamped system will also not oscillate but is damped so ...
