Certainly air provides some damping - but there is a mechanical equivalent
for high inductance and low capacitance and low resistance

spring stiffness? >>

This brings up the interesting question as to what is the mechanical analog
to an electrical circuit. I would think just from intuition that a spring
would serve in a similar manner to a capacitor while mass inertia would be
the equivalent to inductance. Resistance would correlate to the dissipation
of energy by friction.
