A crucial calculus-based resource for the College Board exam is the AP Physics C Mechanics formula sheet. Physics C necessitates the confident application of derivatives and integrals across kinematics, dynamics, energy, and rotational motion, in contrast to algebra-based AP Physics courses.
Knowing when to apply calculus-based formulas and how to use the formula sheet effectively can make the difference between an average score and top performance, as only 24% of American students receive a 4 or 5.

In addition to the cheat sheet, students have access to:
Essential Calculus-Based Formulas for Physics C Mechanics
Kinematics Formulas with Calculus
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.
Dynamics Formulas with Calculus
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:
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.
Frequently Asked Questions – AP Physics C Mechanics Formula Sheet
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.
