WebDemonstration: A damped spring. Set up a suspended mass-spring system with a damper – a piece of card attached horizontally to the mass to increase the air drag. Alternatively, clamp a springy metal blade (e.g. hacksaw blade) firmly to the bench. Attach a mass to the free end, and add a damping card. Show how the amplitude decreases with time. Webnatural logarithm of the initial angular amplitude and the value of the gradient is the constant damping coefficient which is dependent on the type of damping or resistance the pendulum undergoes, for example air resistance and water resistance.
