Overview of AP Physics Classes
There are four AP Physics classes. AP Physics 1 and 2 are algebra-based, focusing on conceptual understanding and problem-solving through algebraic manipulation. Meanwhile, AP Physics C: Mechanics and AP Physics C: Electricity and Magnetism (E&M) are calculus-based, requiring a rigorous application of calculus to analyze complex physical systems.
All AP Physics courses emphasize hands-on laboratory work to promote scientific inquiry and reinforce theoretical concepts through practical experimentation. Labs are also important for developing data analysis and critical thinking skills.
Let’s take a closer look at each of the AP Physics classes below.
AP Physics 1
AP Physics 1 is an algebra-based, introductory college-level physics course that focuses on helping you develop a solid understanding of the fundamental principles of physics. It emphasizes conceptual understanding and problem-solving skills.
Some of the core concepts covered in AP Physics 1 are:
- Kinematics. Kinematics studies the motion of objects without considering the forces that cause that motion, usually using graphs and equations to represent their motion. Some subtopics include displacement, velocity, and acceleration.
- Force and Translational Dynamics. This area explores how forces cause changes in an object’s motion by using Newton’s laws to relate force, mass, and acceleration. It involves analyzing free-body diagrams and understanding how forces affect an object’s translational movement.
- Work, Energy, and Power. This section covers concepts like kinetic and potential energy, and the conservation of energy.
- Linear Momentum. Linear momentum is the product of an object’s mass and velocity, representing its inertia in motion. The conservation of linear momentum explains how momentum is transferred during collisions and interactions.
- Torque and Rotational Dynamics. Torque is the rotational equivalent of force, causing objects to rotate, and rotational dynamics explores how torque affects an object’s angular motion. This includes analyzing angular acceleration, moment of inertia, and rotational equilibrium.
- Energy and Momentum of Rotating Systems. This also relates to rotational dynamics by considering the kinetic energy connected to rotation and the conservation of angular momentum.
- Oscillations. Oscillations are the repetitive motions around an equilibrium point (imagine the simple harmonic motion in springs and pendulums). This area analyzes the relationship between displacement, velocity, and acceleration in oscillatory systems.
- Fluids. This unit introduces the properties of liquids and gases, focusing on concepts like pressure, buoyancy, and fluid dynamics. It explores how forces and motion are applied in fluid systems.
Students tend to find this subject hard because it immediately requires them to work with abstract physics concepts and apply them to different scenarios. To do well in the AP Physics 1 exam, you’ll need a solid grasp of the basics in physics.
AP Physics 2
AP Physics 2 is an algebra-based, introductory college-level physics course that builds upon the foundational knowledge you gained in AP Physics 1. This means you shouldn’t try taking AP Physics 2 without previously taking AP Physics 1 or you’ll be making things harder for yourself.
Core concepts you can expect in AP Physics 2 are:

- Electric Circuits. This unit studies the flow of electric current through conductive pathways, focusing on how voltage, current, and resistance relate to one another. It also looks at the behavior of components like resistors and capacitors.
- Magnetism and Electromagnetism. Magnetism explores the forces exerted by magnets and moving charges, while electromagnetism looks at the interconnectedness of electric and magnetic fields. This unit basically examines how changing magnetic fields induce electric fields and vice-versa.
- Geometric Optics. Geometric optics studies the behavior of light as it interacts with lenses and mirrors, focusing on reflection and refraction. It uses ray diagrams to trace light paths and analyze the formation of images.
- Waves, Sounds, and Physical Optics. This area studies sound waves, interference, and diffraction phenomena. It applies principles of wave superposition to explain optical effects.
- Modern Physics. Modern physics pulls you into the world of quantum physics, exploring atomic and nuclear phenomena and the wave-particle duality of matter. It introduces concepts like quantum mechanics and relativity.
AP Physics 2 might be hard, but it’s still a rewarding experience, allowing you to deepen your understanding of fundamental physics principles. To do well in the AP Physics 2 exam, you should be able to connect the principles taught in this subject with what you’ve learned in AP Physics 1.
AP Physics C: Mechanics
AP Physics C is hard if you don’t have any background in physics or calculus. So we highly recommend taking introductory courses in those subjects before taking this AP class.
AP Physics C: Mechanics is a calculus-based, college-level course designed for students with a strong foundation in physics and mathematics. You can expect a rigorous exploration of mechanics that emphasizes problem-solving and analytical skills.
You might notice that AP Physics C: Mechanics has the same topics as AP Physics 1. However, what makes AP Physics C harder is that it isn’t designed to be an introductory course since it utilizes a calculus-based approach. Below are the core concepts:
- Kinematics. In AP Physics C: Mechanics, kinematics uses calculus to precisely describe motion. It examines displacement, velocity, and acceleration as functions of time through derivatives and integrals. It emphasizes vector analysis and the mathematical relationships between these kinematic quantities.
- Force and Translational Dynamics. This unit eses calculus to analyze how forces cause changes in motion, using Newton’s laws to establish differential equations relating force, mass, and acceleration.
- Work, Energy, and Power. Here, calculus is used to define work as an integral of force over displacement and to analyze energy transformations in systems with different forces. It looks at power as the time derivative of work, enabling the calculation of instantaneous power.
- Linear Momentum. AP Physics C: Mechanics uses calculus to define linear momentum and impulse, applying conservation laws to analyze collisions and systems with changing mass.
- Torque and Rotational Dynamics. Calculus is used in this unit to describe rotational motion, define torque as a vector product, and relate it to angular acceleration through differential equations.
- Energy and Momentum of Rotating Systems. This area uses calculus to derive expressions for rotational kinetic energy and angular momentum, applying conservation laws to analyze rotating systems with changing moments of inertia.
- Oscillations. In this unit, calculus is used to analyze simple harmonic motion and other oscillatory systems, deriving differential equations that describe their behavior.
This course can be hard, but it gives you a very strong foundation if you’re pursuing a STEM career. To do well in the AP Physics C: Mechanics exam, you’ll need a strong grasp of differential and integral calculus.
AP Physics C: Electricity and Magnetism
AP Physics C: Electricity and Magnetism is a calculus-based, college-level course that explores the fundamental principles of electricity and magnetism. It builds on the mathematical rigor of AP Physics C: Mechanics and applies it to electromagnetic phenomena.
While you can technically take E&M without formally taking Mechanics, we still highly recommend having a strong foundation in mechanics and calculus before attempting this AP class.
Some core concepts you’ll encounter are:
- Electric Charges, Fields, and Gauss’s Law. This section uses calculus to analyze the distribution of electric charges and the resulting electric fields. It allows for precise calculations of electric fields in various geometries using integral calculus.
- Electric Potential. Calculus can help examine electric potential by determining the work done per unit charge in moving a charge within an electric field since it often involves line integrals. It helps establish the relationship between electric fields and potential differences, which is important for analyzing energy in electrostatic systems.
- Conductors and Capacitors. This unit applies calculus to analyze charge distribution on conductors and the storage of electric energy in capacitors. It uses integration to calculate capacitance for different geometries and analyze the energy stored inside electric fields.
- Electric Circuits. Calculus is used to analyze transient behavior in circuits, where current and voltage change over time. It lets you compute the exponential charging and discharging processes using differential equations.
- Magnetic Fields and Electromagnetism. This section uses calculus to calculate magnetic fields generated by current-carrying wires and analyze the forces exerted by magnetic fields on moving charges. It utilizes Ampère’s law and the Biot-Savart law, often involving vector integrals.
- Electromagnetic Induction. Calculus helps you understand Faraday’s law and Lenz’s law, allowing you to calculate induced electromotive forces and magnetic flux changes. It also lets you analyze how changing magnetic fields create electric fields and how this relates to induced currents.
AP Physics C: Electricity and Magnetism is probably the most complex AP Physics class since it builds upon what you’ve learned in the previous AP Physics courses. To do well in the AP Physics C: Electricity and Magnetism exam, you’ll need a deep understanding of electromagnetism, which is important if you’re pursuing a career in physics, engineering, or related fields.
Why Is AP Physics Hard?
AP Physics classes, particularly the calculus-based ones, are known to be hard. In fact, if we look at the College Board’s data on the pass rates of AP exams, AP Physics 1 could be considered the hardest AP class. This is because of several factors, such as:
1. Conceptual complexity
AP Physics is hard because the subject matter itself, physics, is abstract. After all, physics deals with fundamental principles governing the universe, which usually involve abstract concepts that are not immediately intuitive to some. You’ll need to grasp theoretical ideas like fields, forces, energy transformations, and quantum phenomena, which need a deep understanding beyond simple memorization.
Many of these physics concepts also involve visualizing phenomena that are not directly observable, such as electric and magnetic fields or quantum behavior. That means AP Physics can be hard if you don’t develop the ability to create and manipulate mental models of these phenomena.
Another reason AP Physics is hard is that concepts are highly interconnected, meaning that understanding one topic often requires a solid grasp of previous ones. That’s why we don’t recommend jumping straight to AP Physics C if you don’t have a good foundation in the basics.
2. Mathematical rigor
Algebra-based AP Physics courses (Physics 1 and 2) require a solid understanding of algebra and trigonometry. That means you’ll need good mathematical manipulation of equations and the application of trigonometric functions to solve problems.
It gets harder in AP Physics C classes, which heavily rely on differential and integral calculus. You’ll need to be very good at applying calculus to solve physics problems, which can be challenging for those without a strong math background. These classes also rely on vector calculus to describe fields and forces.
3. Problem-solving demands
AP Physics is hard since it requires you to analyze complex situations, identify relevant principles, and develop a step-by-step solution. This forces you to develop critical thinking skills to evaluate assumptions and assess if your solutions work.
Physics problems also tend to involve multiple steps and require the application of several concepts and equations, so you should be able to break down complex problems into smaller, manageable parts.
4. Exam structure and rigor
AP Physics exams can be hard since they’re designed to assess a wide range of skills and knowledge, including conceptual understanding, problem-solving, and experimental design.
You can’t just memorize concepts and formulas—especially since you’re required to demonstrate your ability to apply physics principles in different scenarios in the free-response sections. You’ll have to explain your thought processes and support your answers with evidence.
How to Excel in AP Physics Classes
AP Physics classes can be hard. However, you can definitely excel with the right approach. Here are a few tips that can help you thrive in your AP Physics:
1. Establish effective study habits.
Develop a consistent study schedule and stick to it. Set aside enough time to review notes, work through problems, and understand concepts. Practice active learning, such as summarizing concepts in your own words and teaching them to others. AP Physics may be hard, but having good study habits can help you stay on top of your lessons, making them more manageable.
2. Build a strong foundation.
Address any weaknesses in math early on since they can significantly affect your progress in physics. Review fundamental concepts and practice problem-solving to ensure proficiency.
Work through a variety of problems, including those from textbooks, practice exams, and online resources to improve your problem-solving skills. Practice breaking down complex problems into smaller, manageable steps. Regularly working on problems will slowly but surely improve your understanding and speed.
3. Develop conceptual understanding.
Don’t just memorize formulas! Instead, you should also understand the underlying principles and how they relate to real-world phenomena.
AP Physics may be hard, but you can make it a bit easier by using diagrams, graphs, and simulations to help you better visualize abstract concepts. Relating physics concepts to everyday experiences can also make them more tangible and relatable to you.
Strive to be able to explain concepts in your own words. If you can teach the concept to someone else, then you know that you understand it.
4. Utilize resources.
There are many resources available that can help make a hard AP Physics topic more easily digestible to you.
Textbooks and review books are primary resources for learning concepts and working through examples. However, you should also check online platforms like Khan Academy, MIT OpenCourseWare, and AP Classroom for video lectures, tutorials, and more practice problems.
Attend teacher office hours to clarify anything and seek additional help. Working with an AP tutor can provide more personalized instruction and support.
Collaborate with classmates to review concepts, solve problems, and prepare for exams. You can teach and explain concepts to one another to reinforce your own understanding as well.
