Get ready for AP Physics 1 with unit study guides, practice questions, and FRQ practice across all 8 units, from kinematics through fluids. Use these AP Physics 1 resources to practice modeling, graphs, equations, experimental design, and written reasoning for the exam.
AP Physics 1 is an algebra-based course on motion, forces, energy, momentum, rotation, oscillations, and fluids. You reason from evidence, build multi-step solutions, and explain your thinking in clear written form.

browse all 8 unitsAP Physics 1, often searched as AP Physics 1: Algebra-Based, builds your understanding of how objects move and interact. You start with motion and forces, then extend into energy, momentum, rotation, oscillations, and fluids. Instead of memorizing equations, you learn to reason from evidence, model real situations with algebra, and explain your thinking clearly in writing. It is equivalent to the first course in a college introductory algebra-based physics sequence.
The course runs through 8 units that stack on each other, so the foundation you build in kinematics and dynamics carries into every later topic. You work through guided experiments, graph and analyze data, and solve multi-step problems that often combine several concepts at once. That mix of quantitative skill and clear communication is what the exam rewards, and it prepares you for future science and engineering coursework.
Model motion using vectors, graphs, and kinematic equations in one and two dimensions
Draw free-body diagrams and apply Newton's laws to forces and circular motion
Use conservation of energy, momentum, and angular momentum to analyze systems
Connect linear and rotational motion through torque and rotational inertia
Analyze simple harmonic motion and the behavior of fluids under pressure and buoyancy
Design experiments and justify claims with evidence and physics principles
The AP Physics 1 exam runs 3 hours and splits evenly between multiple-choice and free-response questions. Here is how the sections break down.
| Section | Questions | Time | % of Score |
|---|---|---|---|
| Section I – Multiple Choice | 40 | 80 min | 50% |
| Section II – Free Response | 4 | 100 min | 50% |
Total timed testing time: 180 minutes.
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.

Study in the order the units build. Lock in kinematics and force and translational dynamics first, since those ideas show up in nearly every later problem. After each lesson, work problems by hand and write out your reasoning the way the free-response questions expect, rather than just checking final answers. Review the heavily weighted Units 2 and 3 often, and practice problems that combine units like energy with rotation, or momentum with rotational dynamics. As the exam nears, shift to timed FRQ practice across the four question types and the multiple-choice format so you are comfortable explaining and calculating under pressure.
Week 1: Review Units 1 and 2 with kinematics graphs and free-body diagram practice questions
Week 2: Work Units 3 and 4 problems on energy conservation, work, impulse, and collisions
Week 3: Practice Units 5 and 6 torque, rotational inertia, and angular momentum problems
Week 4: Study Units 7 and 8, drilling SHM energy and fluid pressure and buoyancy
Week 5: Do timed multiple-choice sets and review every missed question for the concept gap
Week 6: Complete full FRQ sets across MR, TBR, LAB, and QQT, then grade your written reasoning
Use the question types below to plan written-response practice and connect exam guides to timed FRQs. Open an example prompt to practice that question type right away.
| Question | Focus | Points | % of Score | Example prompt |
|---|---|---|---|---|
| FRQ 1 | Mathematical Routines | 10 | 13% | Horizontal velocity magnitude across different reference frames |
| 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.
