PHY C13: Damped Oscillations

So far we’ve been looking at free oscillations (where the maximum displacement remains constant).

Now we shall look at damped oscillations.

Let’s go!


What is a damped oscillation?
A type of oscillation where its displacement decreases with time due to the presence of a resistive force.

Why does the displacement decrease?
The resistive force (friction etc) causes ENERGY LOSS in the form of HEAT.

There are a few types of damped oscillations, depending on the AMOUNT of damping:

Types Definition Graph Examples
Lightly Damped /
Underdamped system
System oscillates with decreasing amplitude over time Light and Critical Damping Pendulum facing air resistance
Critically Damped system Displacement decreases to 0 in the shortest time possible without oscillating Screenshot 2019-05-04 at 11.42.05 PM.png Car shock absorbers
Overdamped system Displacement decreases to 0 more gradually without oscillating Screenshot 2019-05-04 at 11.42.11 PM.png Door damper
