About the AP Physics 1: Algebra-Based exam

AP Physics 1 is an algebra-based, introductory college physics course that, as of the 2024-25 redesign, spans eight units: kinematics, dynamics (forces and Newton's laws), work/energy/power, linear momentum, torque and rotational motion, energy and momentum of rotating systems, oscillations, and fluids, which moved into Physics 1 from Physics 2. No calculus is required, but strong algebra and a deep conceptual grasp of mechanics are essential. The defining challenge of this exam is that it rewards reasoning, not formula recall. Many questions present novel scenarios and ask you to predict behavior, compare situations, or explain why something happens using physical principles. The free-response section is famous for its qualitative-quantitative translation and paragraph-length argument questions, where you must construct a coherent, logically ordered explanation, and for its experimental design questions that ask you to plan an investigation and analyze authentic data. Students frequently struggle because they memorize equations without understanding when they apply, or they reach for an equation before reasoning through the physics. The redesigned exam uses four-option multiple-choice questions and has removed the older multi-select format. Success depends on building intuition for forces and free-body diagrams, conserving energy and momentum, distinguishing translational from rotational analogs, and clearly communicating reasoning in words. Practicing released free-response questions against official scoring guidelines is invaluable, because points are awarded for specific reasoning steps and correct linkage between representations. Treat graphs, equations, motion diagrams, and verbal descriptions as interchangeable views of the same physics, and you will be well positioned for both sections.
