What would the electrical equivalent circuit of a freely falling body look like and how would we relate the R, L and C in the circuit to the mechanical parameters of the body..??
 

A freely falling body drops slowly at first, then gains more speed over time. Its curve is exponential.

The C and L curves drop quickly at first, then become shallower over time. They are linear devices (as far as the ideal sense).

Consider a diode. As voltage increases linearly, current goes up exponentially. It might better describe a falling body.

Or a battery as it discharges into a load. Volt level falls slowly at first, then quickly as it gets completely discharged.
 

Without considering air resistance, fall speed rises linear in time, travelled path quadratically. There's no RLC equivalent for the differential equation.

Free fall with air resistance is more complicated. See https://en.wikipedia.org/wiki/Free_fall
 

try to think a DC battery connected to an inductor and measure the current.
In an ideal word the current will go to infinite, in a real word the current will be limited by the internal resistance of the battery and of the inductor.
think at he current as the speed of the falling person.
