The Physics Diagnostic Quest is a free AP Physics 1 and AP Physics 2 practice tool built around one of the most critical — and most overlooked — exam skills: knowing which method to reach for before you start solving. Students work through ten physics scenarios covering conservation of energy, conservation of momentum, Newton’s second law, kinematics, and two-stage combination problems, answering four diagnostic questions per scenario to identify what’s physically changing, what the problem is asking for, and which approach fits. It’s conceptual physics problem-solving without the math — pure pattern recognition and method classification. Whether you’re prepping for the AP Physics exam, reviewing mechanics fundamentals, or working on physics problem-solving strategies, this diagnostic helps you move past surface-level guessing and start reading the structure of every problem type.
