Electrostatic Field, Electric Potential, and Electromotive Force: What Actually Pushes the Charges?
Why can the electrostatic field be described by an electric potential? How does a changing magnetic field produce an induced electric field? Starting from path independence and the chemical processes inside a battery, this article clarifies what questions the electric field, force, and electromotive force each answer.

From the unification of electric and magnetic fields, potential energy and simple harmonic motion, to the two different '2's in a movable pulley, we follow concrete examples to ask: why does a formula hold, and what happens when the conditions change?

Starting from molecules hitting walls, we derive the hydrostatic equation and how atmospheric pressure varies with altitude, then explain how pressure gradients change flow, when Bernoulli's equation holds, and why wing lift cannot be explained by "equal transit times."
