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.

The exam

The exam is hybrid digital: you answer the multiple-choice questions in the Bluebook app and handwrite your free-response answers in a paper booklet. A four-function, scientific, or graphing calculator is allowed on both sections of the exam.
