To me those are push and pull, not electrons overpowering push and pull through mass in motion staying in motion. But capacitance and inductance and the movement of electrons and holes in wires seems more about field than mass.
I would ask about wave-forms in wires but stick a resistor in there and it's bye-bye square waves.
I'm more at the level of understanding why plumbing is a half-fast similie to wiring. IIRC from using mass spectrometry, an electron masses around 10^-43rd grams while Avogadro's Number is on a 10^23rd scale. It seems to me that moving electrons are more affected by field than by mass to a very high magnitude.
In terms of Arduino speeds, I don't see no steenking inertia.
