This AP Physics 2 study guide covers electrostatics (charge conservation, conductors/insulators), electric fields and forces (Coulomb's Law, electric potential), DC circuits (Ohm's Law, series/parallel circuits, power/energy), magnetism (magnetic fields, forces on wires, field sources), electromagnetism (induction, transformers), waves and optics (wave properties, reflection/refraction, interference/diffraction), and modern physics (quantum physics, nuclear physics). It includes example problems, key equations, and exam tips.
