The AP Physics C Mechanics formula sheet is provided on exam day, but high scores depend on knowing how to use it efficiently. Unlike algebra-based AP Physics courses, Physics C requires confident use of derivatives and integrals in kinematics, dynamics, energy, and rotational motion.
Only about 24% of U.S. students earn a 4 or 5. The difference between an average and top score is not memorization – it is recognizing when calculus-based forms apply and navigating the formula sheet quickly under pressure.

The AP Physics C Mechanics formula sheet is an official College Board reference document provided during both the multiple-choice and free-response sections. It includes calculus-based equations for motion, force, work, energy, momentum, and rotation — but it does not explain derivations or integration techniques.
Students must already know how to take derivatives and evaluate definite integrals.
Calculus-based equations that go beyond AP Physics 1 algebra are included in the College Board formula sheet. It is crucial to comprehend what is offered and what is not:
| Formula Category | What’s Included | Calculus Elements |
| Kinematics | Relationships between position, velocity, and acceleration | ( v = \frac{dx}{dt} ), ( a = \frac{dv}{dt} ) formulas provided |
| Dynamics | Newton’s Laws, such as the momentum form | ( F = \frac{dp}{dt} ) (calculus form) |
| Work & Energy | Power, kinetic energy, potential energy, and work | ( W = \int \vec{F} \cdot d\vec{x} ) notation shown |
| Linear Momentum | The impulse-momentum theorem and momentum | Impulse expressed as ( \int \vec{F},dt ) |
| Rotational Motion | moment of inertia, torque, angular momentum, and rotational kinetic energy | ( \tau = \frac{dL}{dt} ) (calculus form) |
| Oscillations | Basic formulas for the period and frequency of harmonic motion | SHM differential equations not shown |
| Gravity | Gravitational potential energy and universal gravitation | Standard formulas provided |
| Constants | (G) is the gravitational constant, and (g) is the acceleration brought on by gravity. | Numerical values given |
In addition to the cheat sheet, students have access to:
| Formula Sheet for AP Physics C Mechanics PDF | Practice FRQs and MCQs. |
| Worksheets according to topics | Comprehensive practice exams |
If force, acceleration, velocity, or position changes with time or position, calculus is required.
Constant acceleration formulas (v = v₀ + at) only apply when acceleration is constant.
These relationships form the foundation of all motion problems:
| Relationship | Formula | When to Use | Calculus Application |
| Velocity from position | v = dx/dt | Finding instantaneous velocity | Take derivative of position function |
| Acceleration from velocity | a = dv/dt | Finding instantaneous acceleration | Take derivative of velocity function |
| Acceleration from position | a = d²x/dt² | Second derivative problems | Take second derivative of position |
| Velocity from acceleration | v = v₀ + ∫a dt | Variable acceleration | Integrate acceleration function |
| Position from velocity | x = x₀ + ∫v dt | Finding displacement | Integrate velocity function |
Critical Understanding:
Calculus is required if acceleration, velocity, or position are functions that change over time. The formulas for constant acceleration (v = v₀ + at, etc.) are not applicable.
Newton’s Laws take on calculus forms in Physics C:
| Formula | Standard Form | Calculus Form | When to Use Calculus |
| Newton’s Second Law | ( F = ma ) | ( F = m\frac{dv}{dt} = \frac{dp}{dt} ) | When mass changes or force varies and momentum must be analyzed |
| Impulse | ( J = F\Delta t ) | ( J = \int \vec{F},dt ) | When force varies with time |
| Momentum | ( p = mv ) | ( \frac{dp}{dt} = F ) | When finding force from changing momentum |
Example Application:
If F(t) = 3t², find impulse from t = 0 to t = 4:
Work and energy problems frequently require integration:
| Concept | Formula | Calculus Form | Application |
| Work | W = F·d | W = ∫F·dx | Force varies with position |
| Power | P = W/t | P = dW/dt = F·v | Instantaneous power |
| Kinetic energy | KE = ½mv² | KE = ½m(dx/dt)² | From velocity function |
| Potential energy | PE = mgh | F = -dU/dx | Finding force from PE |
Critical Relationship:
Force is defined as the negative derivative of potential energy (F = -dU/dx). Almost all exams include this.
Example:
If U(x) = 5x² – 3x:
Rotational dynamics parallels linear motion but with angular quantities:
| Linear → Rotational | Formula | Calculus Form | Key Insight |
| Angular velocity | ω = Δθ/Δt | ω = dθ/dt | Rate of change of angle |
| Angular acceleration | α = Δω/Δt | α = dω/dt = d²θ/dt² | Second derivative of angle |
| Torque (Newton’s 2nd) | τ = Iα | τ = dL/dt | When I or ω changes |
| Angular momentum | L = Iω | dL/dt = τ | Change in angular momentum |
| Rotational work | W = τθ | W = ∫τ dθ | Torque varies with angle |
| Rotational power | P = τω | P = dW/dt | Instantaneous rotational power |
Master Physics C Formula Sheet
| Mistake | Why It Costs Points | How to Fix It |
| Using algebra when calculus required | Incorrect method even when the math is right | Consider calculus first if anything changes with t or x. |
| Not recognizing when to use F = dp/dt | Ignoring Newton’s Second Law in its momentum form | Use in momentum problems or when mass changes. |
| Forgetting F = -dU/dx | Potential energy cannot be used to determine force | Practice this relationship, which is present on nearly all exams. |
| Using wrong moment of inertia | Incorrect geometry I value | Examine the formula sheet table closely. |
| Confusing τ = Iα and τ = dL/dt | When calculus form is required, use the simpler form. | When I or ω changes, use τ = dL/dt. |
| Not including limits on integrals | When a definite integral is required, indefinite | Initial and final limits are always necessary for work/impulse problems. |
| Misapplying SHM formulas | Using the incorrect period formula | Pendulum uses L and g, while spring uses k. |
| Searching formula sheet without understanding problem | Spending time attempting haphazard formulas | Determine the relevant formula after identifying the physics concept. |

This guide is structured using:
Our academic review process ensures alignment with current exam standards and scoring practices.
1. Do I get a formula sheet on the AP Physics C Mechanics exam?
Yes. For both Section I (MCQ) and Section II (FRQ), the College Board offers an official formula sheet. It is available to you for the full ninety minutes of the test.
2. Is the Physics C formula sheet different from Physics 1 and 2?
Yes,quite different. While Physics 1 and 2 only use algebra, AP Physics C Mechanics uses calculus-based formulas (v = dx/dt, W = ΨF·dx, τ = dL/dt).
3. What calculus formulas are NOT on the formula sheet?
Integral formulas, integration methods, and derivative rules (power rule, chain rule, and product rule) are not offered. You need to be able to calculate integrals and derivatives on your own.
4. Are moment of inertia formulas provided on the formula sheet?
Yes. The following list includes common moments of inertia: hoop, disk, sphere, rod about center, and rod about end. However, in order to derive non-standard shapes, you need to know that I = Ψr² dm.
5. How should I practice with the formula sheet before the exam?
Beginning in September, use only the official College Board formula sheet for all practice problems and homework. Never use notes or textbooks; instead, mimic the exact conditions of an exam to gain familiarity.
