The most-confusing AP science decision. AP Physics 1 and AP Physics C cover similar topics but with fundamentally different approaches.
Key Difference: Calculus
- AP Physics 1 is algebra-based. No calculus required. Conceptual + algebraic problem solving.
- AP Physics C is calculus-based. You need AP Calc AB or equivalent first. Topics include derivatives and integrals applied to physics.
Coverage
- Physics 1 covers kinematics, Newton's laws, energy, momentum, simple harmonic motion, waves, sound, electric circuits.
- Physics C: Mechanics covers similar mechanics topics but with calc — plus rotational dynamics in depth.
- Physics C: E&M covers electric fields, magnetism, electromagnetic induction with calc.
Note: Physics C is actually two separate exams (Mechanics and Electricity & Magnetism). You can take one or both.
Difficulty
- AP Physics 1: 66% pass rate, 18% 5-rate (College Board rescaled it in 2025). Reasoning-heavy multi-step FRQs.
- AP Physics C: Mechanics: 75% pass rate, 36% 5-rate. Self-selected stronger students.
- AP Physics C: E&M: 70% pass rate, 33% 5-rate. Same self-selection.
The Physics C numbers look better, but that's because mainly serious physics students take them. The actual content is significantly harder.
Which to Take for Engineering
If you're serious about engineering, physics, or pre-med: take both Physics C exams in your senior year, after AP Calc. Physics 1 is a fine junior-year option to build foundation, but college engineering programs respect Physics C more.
