The course is organized into 8 units. The percentages below are the College Board exam weights, so you can see which units carry the most multiple-choice points. Open each unit for its study guide, topic pages, key terms, and practice questions.
AP Physics 1 Unit 1, Kinematics, is the study of how objects move, described with displacement, velocity, and acceleration in one and two dimensions.
AP Physics 1 Unit 2, Force and Translational Dynamics, is where you learn what makes objects speed up, slow down, or stay put.
AP Physics 1 Unit 3 covers work, energy, and power, and it introduces the single most useful problem-solving tool in the course, conservation of energy.
AP Physics 1 Unit 4 is about linear momentum, the product of mass and velocity, and how it changes when forces act over time.
AP Physics 1 Unit 5, Torque and Rotational Dynamics, takes everything you learned about forces and linear motion and rewrites it for things that spin.
AP Physics 1 Unit 6 takes everything you learned about energy and momentum in linear motion and applies it to things that spin.
AP Physics 1 Unit 7 covers oscillations, the back-and-forth motion of systems like a block on a spring or a pendulum swinging through small angles.
AP Physics 1 Unit 8, Fluids, applies the forces and conservation laws from the rest of the course to substances that have no fixed shape, like water and air.
These trends come from real Fiveable practice data, so you can see what students are reviewing, which topics need extra attention, and how written practice can improve over time.

Skim the 8 unit pages, then choose the units that need the most review. Use topic guides for the concepts that feel fuzzy instead of rereading the whole course.
After each unit, answer practice questions and write free responses when they are part of the subject. Keep a short list of missed skills and revisit those guides before the next set.
Use exam guides, cheatsheets, score calculators, and practice exams when they are available for this course. The best final review plan connects content, question types, and timing.

| FRQ 2 | Translation Between Representations | 12 | 15% | Projectile motion velocity components and range |
| FRQ 3 | Experimental Design | 10 | 13% | Cart velocity measurement using motion analysis |
| FRQ 4 | Qualitative/Quantitative Translation | 8 | 10% | Projectile motion horizontal distance comparison |
AP Physics 1 is one of the more demanding AP courses because it asks you to reason through problems and explain your thinking, not just plug numbers into formulas. Concepts stack across 8 units, so a shaky start in kinematics or forces slows you down later. It stays manageable when you practice multi-step problems consistently and write out reasoning the way the free-response questions expect.
Start with the early units, since kinematics and force and translational dynamics carry through everything else. Work practice problems by hand right after each lesson instead of re-reading notes, and write out your reasoning. Then layer in energy, momentum, and rotation. Use unit study guides and practice questions on Fiveable to organize your review and find concept gaps before they grow.
On the multiple-choice section, Unit 2 (Force and Translational Dynamics) and Unit 3 (Work, Energy, and Power) each carry 18 to 23 percent, the largest shares. Units 1, 4, 5, and 8 each fall in the 10 to 15 percent range, while Units 6 and 7 each sit at 5 to 8 percent. Prioritize Units 2 and 3 since they anchor much of the exam.
The free-response section has 4 questions worth 50 percent of your score, with 100 minutes total. They appear in a set order: Mathematical Routines, Translation Between Representations, Experimental Design and Analysis, and Qualitative/Quantitative Translation. Across these, you derive symbolic relationships, calculate values, draw diagrams and graphs, design experiments, and justify claims with clear physics reasoning.
No. AP Physics 1 is algebra-based, so you use algebra and basic trigonometry rather than calculus. You should have completed Geometry and be taking Algebra II or an equivalent course. The trig you need can be picked up in your concurrent math class or in the course itself, so prior physics experience is not required to get started.
