AP Physics 2: Algebra-Based
Circuits, fields, light and atoms
AP Physics 2 picks up where Physics 1 stops: heat and gases, electric charge and circuits, magnetism and induction, mirrors, lenses and waves, and the physics of atoms and nuclei. Each lesson asks you to predict before it explains, and every wrong answer says which mistake it comes from. The lessons are being written one unit at a time.
