In simple harmonic motion, the damping force is generally proportional to the velocity of the oscillating mass, according to the State University of New York Stony Brook.

Figure 1: Devices and measurement setup. (Supplementary Section D). This simple relation is all the more surprising because it is very close to that of a simple harmonic oscillator. Figure 4 ...

As before, the first column shows the nominal 8 ohm damping factor, the second shows the corresponding output resistance of the amplifier. The second and third columns show the minimum and maximum ...
