AP Physics 1 vs AP Physics C

By Ashraf Bhura, Co-Founder, STEM-Tutor · Updated October 2026

AP Physics 1 is algebra-based. AP Physics C uses calculus. Here is how they compare and how to choose.

The main difference

AP Physics 1 covers mechanics using algebra and trigonometry. AP Physics C: Mechanics covers similar topics with calculus, and AP Physics C: Electricity and Magnetism is a separate calculus-based course. Physics C is closer to the first physics courses that engineering and physics majors take in college.

Side by side

• Maths: Physics 1 needs algebra and trigonometry. Physics C needs calculus, ideally already studied or taken at the same time.
• Content: both cover kinematics, forces, energy, momentum, rotation and oscillations. Physics 1 also includes fluids.
• Style: Physics 1 focuses on conceptual reasoning and explanation. Physics C includes more derivations and calculus-based problem solving.
• Pace: Physics C usually moves faster.

Which is harder?

Neither is simply harder. Physics 1 catches students who memorise formulas without understanding. Physics C is demanding mathematically but many strong maths students find its problems more structured. See our guide on how hard AP Physics is for more.

How to choose

• Planning engineering, physics or computer science? Physics C is usually the better fit, if your calculus is ready.
• First physics course, or calculus not yet started? Physics 1 builds strong foundations.
• College credit: policies vary. Many engineering programmes prefer Physics C. Check the AP credit pages of the colleges you are considering.

Course details change over time, so check the current course descriptions on AP Central.

The same problem in both courses

Seeing one situation solved both ways shows the real difference.

Physics 1 version

A 2 kg block is pushed by a constant 10 N force for 3 s from rest on a frictionless floor. Find its final speed.

• a = F/m = 5 m/s², so v = at = 15 m/s.

Physics C version

The same block is pushed by a force that grows with time: F(t) = 4t newtons. Find its speed at t = 3 s.

• a(t) = F/m = 2t, so v(t) = ∫₀^t 2t dt = t².
• At t = 3 s, v = 9 m/s.

Physics 1 handles constant quantities with algebra. Physics C uses calculus to handle quantities that change.

Typical student paths

• Path 1: AP Physics 1 in Grade 10 or 11, then AP Physics C in Grade 12 alongside or after calculus.
• Path 2: straight to AP Physics C in Grade 11 or 12 for students strong in maths who are taking calculus.
• Path 3: AP Physics 1 and then AP Physics 2, for students who want broad algebra-based physics, often heading toward life sciences.

Your school's course offerings and calendar will shape which path is possible.

Questions to ask yourself

1. Am I comfortable with derivatives and integrals, or will I be by the middle of the year?
2. Do I enjoy explaining ideas in words, or do I prefer working through mathematical derivations?
3. Which colleges and majors am I aiming for, and what do they say about AP credit?
4. How heavy is the rest of my schedule this year?

Frequently asked questions

Can I take AP Physics C without taking AP Physics 1 first?

Yes, many students do, especially if they are strong in maths. Some prior physics helps, but it is not required.

Is Physics C Mechanics one exam or two?

AP Physics C: Mechanics and AP Physics C: Electricity and Magnetism are separate exams with separate scores. Many students take Mechanics first.

Do colleges prefer one over the other?

Engineering and physics programmes often prefer Physics C. Policies differ, so check each college's AP credit page.

What each course feels like week to week

AP Physics 1

Classes spend a lot of time on reasoning: predicting what will happen, explaining why, and drawing diagrams and graphs. Homework mixes calculations with short written explanations. Labs often ask you to design an experiment. Students who enjoy discussing ideas and explaining them in words often thrive.

AP Physics C: Mechanics

Classes move quickly through mechanics and lean on calculus: setting up integrals, solving simple differential equations and deriving results. Homework is more mathematical and often longer per problem. Students who enjoy maths and want to see why the equations are true usually thrive.

A sample decision

A Grade 11 student is taking AP Calculus AB this year, plans to study mechanical engineering and has never taken physics. Physics C: Mechanics is a realistic choice, because calculus is being learned at the same time, and engineering programmes value it. A strong introductory physics background or summer preparation helps, because Physics C assumes you can learn concepts quickly.

A Grade 10 student in Algebra 2 who is curious about physics and unsure about their major would be better served by AP Physics 1. It builds the conceptual foundations, and Physics C can follow later.

More questions students ask

Is AP Physics C easier if I have taken AP Physics 1?

Usually yes. You will already know the concepts and can focus on the calculus methods.

Can I take AP Physics 1 and AP Physics C in the same year?

Some students do, but it is a heavy load and the courses overlap a lot. Most schools offer them in different years.

Does AP Physics C include waves or optics?

No. Physics C covers mechanics and electricity and magnetism only. Waves, optics and thermodynamics appear in AP Physics 2.

Which is better for medicine?

Pre-med students often take AP Physics 1 and AP Physics 2, which match algebra-based college physics. Check the requirements of the programmes you are considering.
