How to damp oscillations?

In what ways could you damp an oscillation? I know that damping requires energy lost, by friction and air resistance... but what can cause this friction or air resistance? Could someone give me examples? :confused:

:confused:

Sticking it in water?

Thinking about it, there are loads of ways you can damp stuff!

Yes sticking it in water is a good example, also when a pendulim is oscillating it will gradually stop because of air resistance (this is light damping).

A damper

In car suspension anyways.
Otherwise, immerse in a viscous fluid. Mount oscillator on deforming (i.e. rubber) mounts, loads of ways!

In a pipe cladding to increase air resistance / friction increase surface area somehow ie with a pendulum put a piece of paper on the string

Well, water damps in more than one way :wink:

:wink:

But yeah, the more viscous the medium the object is oscillating in the more damped it's oscillations will be.
