AP Physics is generally regarded as one of their more challenging offerings; with four courses available, most students only take one or two, and knowing which to take and the differences between them can be tricky. Additionally, College Board announced changes to the exams and curriculum for the 2024-25 school year. We thought that this would be a good time to give an overview of these courses, and what they require. 

We’ve discussed AP tests before, but in this article we’re going to dive into the physics courses more deeply. We’re going to explain what each one is and the differences between them (along with the new updates). We’re also going to look at which you should consider taking, and how valuable they might be for your college plans. Let’s get started!

What’s the Difference Between the AP Physics Courses?

AP Physics comes in four varieties: 

  • AP Physics 1
  • AP Physics 2
  • AP Physics C: Mechanics
  • AP Physics C: Electricity and Magnetism

The naming convention for the courses is often an initial point of confusion. After all, counting 1, 2, C is generally considered bad form. Here, however, the C stands for Calculus; as calculus is required to fully grasp the content in these courses. Here’s a quick rundown of the differences between the courses, then we’ll go into more detail: 

CoursePre-RequisitesCovers
AP Physics 1Completed Geometry and currently taking Algebra IIKinematics, Forces and Translational Dynamics, Work, Energy, and Power, Linear Momentum, Torque and Rotational Dynamics, Energy and Momentum of Rotating Systems, Oscillations, and Fluids
AP Physics 2Completed AP Physics 1 (or equivalent), and currently taking PrecalculusThermodynamics, Electric Force, Field, and Potential, Electric Circuits, Magnetism and Electromagnetism, Geometric Optics, Waves, Sound, and Physical Optics, and Modern Physics
MechanicsHave taken or be concurrently taking CalculusKinematics, Forces and Translational Dynamics, Work, Energy, and Power, Linear Momentum, Torque and Rotational Dynamics, Energy and Momentum of Rotating Systems, and Oscillations
Electricity and MagnetismHave taken AP Physics 1 or AP Physics C mechanics, and have taken calculusElectric Charges, Fields, and Gauss’s Law, Electric Potential, Conductors and Capacitors, Electric Circuits, Magnetic Fields and Electromagnetism, and Electromagnetic Induction

All of the AP Physics courses also have a lab component, meaning that in addition to theoretical work, you will complete hands-on experiments as part of these courses. While these experiments will not be done as part of the exam, they will help you understand and demonstrate the principles you are learning. 

Now we’ll go over each course in a little more detail. 

AP Physics 1

This is the equivalent of an introductory physics class in college, and covers all of the basic principles of physics. Significant math is required, but this is true of all physics courses. This is the class taken by the most students who take AP Physics, as it has the fewest prerequisites, and is offered by the most schools. 

AP Physics 2

This is meant to be the equivalent of a second semester of introductory college physics. This course builds upon and expands the material from AP Physics 1, and requires a greater degree of mathematical knowledge. Fewer students take this course, as those who want to do multiple years of physics usually go on to the Physics C coursework. This is not to say that Physics 2 is useless, but it is not seen as being as advanced or challenging as either of the Physics C courses. 

AP Physics C: Mechanics

In many ways, AP Physics C covers the same material as AP Physics 1. If you look at the topics covered in the chart above, you can see they are nearly identical (AP Physics 1 now covers fluids, which was a change this year, but they are otherwise the same). AP Physics C is calculus based however, and covers these topics at a higher level; the college course is Calculus-Based physics, which is more likely what most students will take in college. 

If you have the mathematical preparation, and a choice between Physics 1 and Physics C, we recommend the latter, especially if you are interested in pursuing STEM fields in college. While the material is very similar, Physics C provides a better base for advanced courses, and demonstrates better your interest in these advanced academic topics. 

AP Physics C: Electricity and Magnetism

This course is more specialized than the others, and focuses more narrowly on a single field within physics. It is also a more advanced course, requiring some knowledge of physics as a prerequisite. This course is generally taken during senior year for that reason, as the final science course students take in high school. 

This course is slightly more popular than mechanics, as most students take Physics 1, and then if they take another physics course, move onto E&M. This is because of the similarity in topics of Physics 1 and Mechanics. E&M is a difficult course, but well worth it for students who plan on entering a STEM field. It, and its exam, are regularly regarded as among the hardest APs. 

Preparing for AP Physics Exams

Of course, part of the appeal of AP classes is the AP exam, the test which can award college credit to high scoring students, and which serves as a culmination of everything you learned and mastered in the course. The first step for preparing for these xams is doing well in the courses themselves; everything you see on the test will mirror what you have learned in the course. 

You need to master the content of these courses both conceptually and practically. This means you not only need to know which formula to use in a given situation, but why it is the one to use, and some level of how it works. This higher level of understanding will let you answer questions more smoothly, and adjust to new variables in them. 

Physics builds upon itself in many ways, with some concepts you learned previously appearing again in later questions or sections. Thus, if you don’t understand something early in a course, go back and review it until you do, or you will find the same issues tripping you up repeatedly. 

Finally, it’s better to study a little over a longer duration than cramming all at once, especially for a field like physics. While many of the areas build upon and complement each other, others do not. You should review periodically throughout the year to keep your knowledge and understanding fresh. That way, when it comes time to sit for the actual AP test, you will have far less work to do.

When it comes time to prepare for the tests themselves, we recommend using College Board’s study materials. They are a monopoly, but since they’re the ones who make the test, they know best what’s on it, and the kinds of questions you will be asked. When reviewing, spend the most time on the concepts which you understand the least, and build from there. 

Final Thoughts

AP Physics offers students a chance to take advanced topics, and begin building the foundation they will need for higher level explorations in STEM. We hope this article has given you a solid introduction to how these courses work, and which students will benefit the most from taking them. Of course, if your school doesn’t offer any AP Physics courses, then you won’t be penalized for giving them a pass, but we do recommend checking them out if they are available. 

Picking the right courses to take in high school can be difficult, as students are often unsure which will best support them, or what colleges want to see in their high school coursework.

Below is my son's review. He was accepted to his dream Ivy League school!

From an admitted student's perspective, I am incredibly grateful to have met Sasha - he has been instrumental in helping me achieve my educational dreams (Ivy League), all while being an absolute joy (he's a walking encyclopedia, only funnier!) to work with.

Many people are dissuaded from seeking a college counselor because they think they can get into their desired college(s) either way. Honestly, going that route is a bit short-sighted and can jeopardize your odds of acceptances after years of hard work. The sad truth is, the American education system (even if you attend a fancy private school and ESPECIALLY if you go to a public school) doesn't really tell students how to write a compelling and authentic application. Going into the admissions process alone, without speaking with an advisor, is like going to court without a lawyer - you put yourself at a significant disadvantage because you don't have all the facts in front of you, or the help you need to negotiate the system.

That said, you need a good lawyer just like you need a good college counselor. And that's where Sasha distinguishes himself from the crowd of people claiming they'll get you into Harvard. I came to Sasha worried about and frankly dumbfounded by the college admissions process. I was unsure what to write about and how to go about drafting the essay that perfectly captured my passion, interests, and self. And I was highly skeptical that anyone could really help me. But, damn, did Sasha prove me wrong. From the beginning, Sasha amazed me with his understanding of the process, and ability to lend clarity and direction to me when I desperate needed it. After interviewing me about my background, experiences, activities, outlook, and vision, he helped me see qualities about myself I had not previously considered 'unique' or 'stand-out.' This process of understanding myself was so incredibly important in laying the groundwork for the essays I eventually wrote, and I'm certain I would've drafted boring, inauthentic essays without it.

Looking back, Sasha's talent is that he can see where your strengths lie, even when you don't see them. The truth is, although we don't always realize it, everyone has a unique story to tell. Sasha helped me see mine, and with his big-picture insight I was able to write the application that truly encapsulated my life and vision. He inspired me to dig deeper and write better, challenging me to revise and revise until my essays were the most passionate and authentic work I had ever written. As clichéd as that sounds, that's really what universities are looking for. In retrospect, it makes sense - in the real world passionate (not simply intelligent) individuals are the ones who make a difference in the world, and those are the individuals colleges would like to have associated with their brand.

In the end, I was accepted to the college of my dreams, a feat I could not have achieved without the direction Sasha lent to me. Essays (and the personal narrative you develop through your application) matter so much, and can literally make or break your application. I have seen so many of my 'qualified' friends receive rejections because they wrote contrived essays that didn't truly represent who they were; conversely, I have also seen so many friends with shorter resumes accepted because they were able to articulate their story in a genuinely passionate and authentic way - I fall into the latter category.

As a former admissions officer at Johns Hopkins, Sasha knows what types of essays jibe well with universities, an invaluable asset to have in the admissions process. He is responsive, flexible, creative, positive, and witty. For anyone who is serious about going into the college admissions process informed and prepared, I highly recommend Sasha.

I used Ivy Scholars to mainly help me with college applications. Within weeks of using this service, Sasha was able to simplify the already complex process. When it came to writing the Common App essay, Sasha didn’t just help with grammar and syntax, he brought my essays to life. Sasha also worked tirelessly to help solidify my extracurricular activities, including research and internship opportunities. Without his help, I would have never had an impressive resume.

Sasha is not only an extremely knowledgeable tutor, but also a genuine brother figure. His guidance, throughout my last two years of high school, was everything I needed to get me an acceptance letter from my dream schools (UC Berkeley, Tufts, Emory).

When it came to testing, Ivy Scholars worked like a charm. Sasha offered a very comprehensive plan when it came to completely acing my standardized tests. Without his test taking strategies I would have never gotten straight 5s on my AP tests and a 35 on the ACT.

Working with Sasha, I didn’t just become a good student, I became a genuine scholar.

We worked with Ivy Scholars during my son's senior year. I was concerned that we may be too late to take advantage of college advising but the Ivy Scholars team quickly and confidently directed us through the steps to ensure no deadlines were missed. Sasha's knowledge about schools, what they looked for in candidates, and how to maneuver the application process was invaluable. Mateo and Ryan worked with my son to help him create an essay that would get noticed and I am so appreciative he had their guidance.

Prior to securing Ivy Scholars, we tried using a less-expensive online service which was a terrible experience. As a parent, Ivy Scholars brought peace of mind to an area that was frankly overwhelming. This service was invaluable in the knowledge that we gained throughout the process. He has also met with my freshman daughter to provide guidance for her high school courses, career paths, extracurricular activities, and more.

Prior to signing with Ivy Scholars, I tried a less expensive online service and was very disappointed.

As a result of our work with Ivy Scholars, I am pleased to say that my son will be attending Stern Business School at New York University this fall! I highly recommend Ivy Scholars. Highly recommend!
