The College Board provides the AP Physics 2 formula sheet during the test, but mastering its use is crucial for high scores. Thermodynamics, fluids, electricity, magnetism, optics, and contemporary physics formulas are all included in the sheet. Before an exam, students who practice using formulas do much better, particularly on free-response questions that call for unit analysis and justification.
Thousands of American high school students use these College Board-aligned formula sheets and equation guides to get ready for the AP Physics 2 exam. Every resource adheres to the most recent AP curriculum framework.

The College Board provides a standardized formula sheet during the AP Physics 2 exam. However, students must know how to select and apply equations correctly to earn points.
| Unit / Topic | Key Formulas & Concepts Tested | Exam Weight |
| Thermodynamics | Heat transfer, entropy, ideal gas law, first law of thermodynamics, and PV diagrams | 18-22% |
| Mechanics of Fluids | Bernoulli’s equation, buoyancy, pressure, fluid dynamics, and continuity equation | 6-8% |
| Potential, Field, and Electric Force | Equipotential lines, electric potential energy, electric field, and Coulomb’s Law | 10-12% |
| Circuits with electricity | 10-14% | |
| Electromagnetism and Magnetism | Kirchhoff’s rules, RC circuits, Ohm’s Law, series/parallel circuits, and power | 10-14% |
| Physical and Geometric Optics | Faraday’s Law, Lenz’s Law, electromagnetic induction, magnetic force, magnetic field, reflection, lenses, mirrors, interference, and diffraction | 10-14% |
| Nuclear, Atomic, and Quantum Physics | Atomic models, nuclear reactions, photon energy, photoelectric effect, and mass-energy | 10-14% |

Critical for U.S. Students: Thermodynamics alone takes up nearly 20% of the test. Any formula sheet must include the first law of thermodynamics, PV diagrams, and ideal gas law applications.
The 3-hour AP Physics 2 exam tests formula mastery differently across sections. Understanding this structure helps American students allocate study time effectively.
| Exam Section | Format | Duration | Weight | How Formulas Are Tested |
| Section I: Multiple Choice | 50 questions (45 single-select, 5 multi-select) | 90 minutes | 50% | Formula selection, conceptual relationships, qualitative reasoning |
| Section II: Free Response | 4 questions (1 experimental design, 3 short answer) | 90 minutes | 50% | Deriving solutions, justifying equation choice, showing all work with units |
In addition to the cheat sheet, students have access to:
| Formula Sheet for AP Physics 1 PDF | Practice FRQs and MCQs. |
| Worksheets according to topics | Comprehensive practice exams |
All resources are aligned with the U.S. AP exam structure and College Board scoring guidelines.
These constants are included in the College Board equation sheet. Before the test day, American students should practice using them:
| Constant | Symbol | Value (SI Units) | Common Uses |
| Proton mass | m_p | 1.67 × 10⁻²⁷ kg | Nuclear physics and mass-energy computations |
| Neutron mass | m_n | 1.67 × 10⁻²⁷ kg | Binding energy and nuclear reactions |
| Electron mass | m_e | 9.11 × 10⁻³¹ kg | Photoelectric effect and quantum physics |
| Electron charge (magnitude) | e | 1.60 × 10⁻¹⁹ C | Circuits, electric force, and quantum |
| Speed of light (vacuum) | c | 3.00 × 10⁸ m/s | Photon energy, relativity, and optics |
| Planck’s constant | h | 6.63 × 10⁻³⁴ J·s | Photon energy and quantum mechanics |
| Universal gravitational constant | G | 6.67 × 10⁻¹¹ m³/(kg·s²) | In Physics 2, it is rarely used, but it offers |
| Boltzmann’s constant | k_B | 1.38 × 10⁻²³ J/K | Kinetic theory and thermodynamics |
Pro Tip: These precise values are provided by the College Board. Use the given constants for accuracy and consistency rather than learning various approximations by heart.
| Mistake | How It Appears on Exams | How to Fix It |
| Using the wrong gas constant | Using R = 0.0821 L·atm/(mol·K) in energy calculations | Use R = 8.31 J/(mol·K) for thermodynamics problems |
| Confusing electric field and potential | Using E = kQ/r² when the question asks for V = kQ/r | Electric field = force/charge; potential = energy/charge |
| Forgetting negative signs | Ignoring the negative in Faraday’s Law (Lenz’s Law) | The negative sign shows the direction of induced current |
| Mixing up lens/mirror conventions | Incorrect signs for real vs. virtual images | Real images: +dᵢ, virtual images: –dᵢ |
| Wrong units in ideal gas law | Using atm instead of Pa or °C instead of K | Convert to Pa and Kelvin (K = °C + 273) |
| Missing sin θ in magnetic force | Using F = qvB when motion isn’t perpendicular | Use F = qvB sin θ unless θ = 90° |
Although it is more difficult than Physics 1, AP Physics 2 has a marginally higher score. According to recent College Board data:
| AP Score | Qualification Level | % of U.S. Students (2024) | College Credit Impact |
| 5 | Extremely well qualified | ~5% | Credit at nearly all colleges |
| 4 | Well qualified | ~11% | Credit at most colleges |
| 3 | Qualified | ~31% | Credit at many colleges |
| 2 | Possibly qualified | ~36% | Rarely earns credit |
| 1 | No recommendation | ~17% | No credit |
1. Do I get a formula sheet on the AP Physics 2 exam?
Yes. On exam day, the College Board gives each student an official formula sheet. It does not, however, provide definitions for variables, units, or instructions on when to apply each formula.
2. What’s the difference between AP Physics 1 and AP Physics 2 formula sheets?
AP Physics 1 covers mechanics and waves (kinematics, dynamics, energy, momentum, rotation). Thermodynamics, fluids, E&M, optics, and modern physics are all covered in AP Physics 2. These subjects are entirely distinct and call for different formulas.
3. Should I memorize AP Physics 2 formulas even though the sheet is provided?
You don’t have to commit the formulas themselves to memory, but you must understand the proper units, the variables’ meanings, and when to apply each one. Formula recognition and selection speed are critical.
4. Where can I download the official AP Physics 2 formula sheet?
The official sheet is available on the College Board website under AP Physics 2 exam resources. TestprepKart also provides annotated versions with variable definitions and example applications.
5. What are the most important formulas on AP Physics 2?
High-yield formulas (appear frequently):
