🎡AP Physics 1 Review
AP Physics 1 covers 8 units, from Kinematics to Fluids. Review each unit with study guides, practice questions, and key terms — compiled by AP educators and updated for the 2027 AP 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.
Frequently Asked Questions
Is AP Physics 1 hard?
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.
How do I start studying for AP Physics 1?
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.
Which units are weighted most on the AP Physics 1 exam?
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.
How many free-response questions are on the AP Physics 1 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.
Do I need calculus for AP Physics 1?
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.
