AP Physics C: Mechanics Study Guide: 7 Units & 2027 Exam

Plan the course with the current seven-unit framework, review the May 2027 hybrid digital exam, and move into focused calculus-based mechanics notes. This guide follows the current College Board structure rather than the older outline that treated gravitation as a separate final unit.

Important course update: the current framework ends with Unit 7: Oscillations. Gravitation remains an important application of force, energy, momentum, and orbital motion, but it is no longer organized as a separate Unit 7 in the official outline.

What AP Physics C: Mechanics covers

AP Physics C: Mechanics is a semester-long, calculus-based introductory college physics course. Students model motion, forces, energy, momentum, rotation, and oscillations using derivatives, integrals, graphs, diagrams, experiments, and written scientific arguments. The course is especially useful for students preparing for engineering, physical science, or another major that requires calculus-based physics.

College Board recommends that students have taken calculus or be enrolled in it at the same time. You should be ready to interpret a derivative as a rate of change, an integral as an accumulated quantity, and vectors as physical quantities with direction. Strong algebra and trigonometry still matter because most errors occur before the final calculus step.

If you want an algebra-based introduction first, use the updated AP Physics 1 study guide. Students planning a full Physics C sequence can continue with the AP Physics C: Electricity and Magnetism guide. You can also compare options in the complete AP subjects directory.

The 7 AP Physics C: Mechanics units for 2026–27

These official ranges describe the approximate share of scored multiple-choice questions. They are useful for planning review, but free-response questions can combine ideas from several units.

10%–15%

Unit 1: Kinematics

Describe one- and two-dimensional motion with vectors, functions, derivatives, integrals, graphs, and relative-motion reasoning. Translate fluently between equations and physical representations.

Build the calculus-based kinematics foundation

20%–25%

Unit 2: Force and Translational Dynamics

Define a system, draw a complete free-body diagram, and apply Newton's laws to equilibrium, accelerating, circular, drag, spring, and gravitational situations.

Review Newton's first and second laws

15%–25%

Unit 3: Work, Energy, and Power

Relate work to energy transfer, obtain force from a potential-energy function, and use conservation laws before committing to a component-by-component force analysis.

Practice the work–energy theorem

10%–20%

Unit 4: Linear Momentum

Use impulse, center of mass, system boundaries, and conservation of momentum to analyze collisions, explosions, and motion of multiple-particle systems.

Study momentum and particle systems

10%–15%

Unit 5: Torque and Rotational Dynamics

Connect torque, angular acceleration, rotational inertia, rolling constraints, and equilibrium. State the rotation axis and sign convention before writing an equation.

Strengthen torque and rotational statics

10%–15%

Unit 6: Energy and Momentum of Rotating Systems

Apply rotational kinetic energy, rolling energy, angular impulse, and conservation of angular momentum. Track external torque and the chosen system carefully.

Review angular-momentum conservation

10%–15%

Unit 7: Oscillations

Model springs and pendulums with differential equations, phase relationships, energy, period, and small-angle approximations. Read motion and energy information from graphs.

Study simple harmonic motion

AP Physics C: Mechanics exam format for May 2027

The 2027 exam is scheduled for Monday, May 3, 2027, Session 1. It is hybrid digital: students complete multiple-choice questions and view free-response prompts in Bluebook, then handwrite free-response answers in a paper booklet.

Section	Questions	Time	Score
Section I: Multiple Choice	42	85 minutes	50%
Section II: Free Response	4	95 minutes	50%

The four free-response questions target mathematical routines, translation between representations, experimental design and analysis, and qualitative/quantitative translation. A permitted calculator may be used on both sections, and reference information is provided. A correct numerical answer without a defensible setup may not earn full credit, so show the model, system, equation, and reasoning.

A professional study plan for Physics C: Mechanics

1. Model first

Name the system, draw a diagram, choose coordinates, and write the relevant law symbolically before inserting values.

2. Connect calculus

Explain what every derivative or integral means physically. Check units, limits, signs, and whether the answer matches the graph.

3. Retrieve and mix

Use spaced mixed practice. Revisit each error after one day and one week instead of repeating only familiar chapter problems.

Use laboratory work as exam preparation

AP Physics C courses should devote at least 25 percent of instructional time to hands-on laboratory investigations. Keep a lab notebook or digital portfolio containing the question, variables, apparatus, procedure, raw data, graphs, uncertainty, conclusion, and improvements. Experimental-design questions reward clear measurable quantities and a method that can actually test the proposed relationship.

Practice with current expectations

Derive a relationship before substituting numbers, and state assumptions such as negligible drag or a massless string.
Translate among a physical situation, graph, diagram, equation, and verbal claim.
Use released questions selectively: older questions are valuable practice, but some do not fully match the revised framework and exam format.
Keep an error log organized by concept, representation, calculus, algebra, experiment design, and time management.
