Each guide is a self-contained, interactive HTML file — works offline, tracks progress in your browser, and has a print mode. Built for the revised exam: 40 MCQs (50%) and 4 FRQs (50%) in the four official formats. Every unit carries a 50-question MCQ bank and 12 FRQs, revealed in batches as you practice.

Unit 1 Kinematics Exam weight 10–15% Describing motion before explaining it — position, velocity, acceleration, projectiles, and the graphs that connect them. 34vocab21laws50MCQs44FRQ parts Unit 2 Force & Translational Dynamics Exam weight 18–23% Newton’s three laws, free-body diagrams, friction, springs, circular motion, and gravitation — tied for the heaviest unit. 34vocab20laws50MCQs48FRQ parts Unit 3 Work, Energy & Power Exam weight 18–23% Energy bookkeeping — choose the system, track the transfers, and answer questions kinematics can’t touch. 30vocab20laws50MCQs42FRQ parts Unit 4 Linear Momentum Exam weight 10–15% Impulse, conservation of momentum, and the collision taxonomy — Newton’s third law in disguise. 28vocab19laws50MCQs42FRQ parts Unit 5 Torque & Rotational Dynamics Exam weight 10–15% Rotation is translation with a dictionary — torque, rotational inertia, Στ = Iα, and equilibrium. 32vocab18laws50MCQs45FRQ parts Unit 6 Energy & Momentum of Rotating Systems Exam weight 5–8% Rolling, angular momentum, the skater’s spin, and orbits — two ledgers, energy and angular momentum. 28vocab19laws50MCQs45FRQ parts Unit 7 Oscillations Exam weight 5–8% Simple harmonic motion — springs, pendulums, the three phase-shifted graphs, and energy sloshing between stores. 30vocab20laws50MCQs39FRQ parts Unit 8 Fluids Exam weight 10–15% · New unit Pressure, buoyancy, continuity, and Bernoulli — new to AP Physics 1 with the 2024–25 revision. 31vocab19laws50MCQs45FRQ parts

STRATEGYHow to Use These Guides

FBD First, Always

Nearly every dynamics point starts with a correct free-body diagram. Draw it before touching an equation — the Laws & Principles cards show what belongs on it.

Know the Equation Sheet

Gold dots in the Equations section mark what’s on the official sheet. Knowing what’s there (and what isn’t) saves minutes on exam day.

Practice All 4 FRQ Formats

Every unit has one FRQ in each official format: Mathematical Routines, Translation Between Representations, Experimental Design & Analysis, and Qualitative/Quantitative Translation.

Answer + Reasoning = Points

AP Physics readers credit correct physics reasoning, not bare answers. Write your response before revealing the model, then compare against the scoring notes.

Design Experiments Out Loud

The Lab section in every unit walks a real experimental-design scenario — variables, procedure, linearization, uncertainty. That’s a full FRQ format worth 10 points.

Hunt Your Misconceptions

The Pitfalls section lists the exact traps the exam plants — “negative acceleration means slowing down,” “third-law pairs cancel.” Read them before every test.
