AP Physics C: Electricity and Magnetism
AP Physics C is made up of two separate, semester-length courses — Mechanics, and Electricity and Magnetism. Most schools teach Mechanics first, and some instructors choose to offer only that portion. When both are taught in a single year, they should each get roughly equal time. Both courses emphasize guided inquiry and student-centered learning to build critical thinking skills, and they consistently use introductory differential and integral calculus.
The Mechanics course addresses six core topics: kinematics; Newton’s laws of motion; work, energy and power; systems of particles and linear momentum; circular motion and rotation; and oscillations and gravitation.
Electricity and Magnetism concentrates on five major areas: electrostatics; conductors, capacitors and dielectrics; electric circuits; magnetic fields; and electromagnetism.
In many colleges and universities, similar courses include extra material such as wave motion, kinetic theory and thermodynamics, optics, alternating current circuits, or special relativity. The most common additions are wave motion, optics, and thermodynamics, but there is no standard set of topics, and none of these appear on the AP Physics C Exams. The Development Committee suggests that teachers supplement Physics C with additional content whenever possible. A popular time for enrichment is late in the year, after the AP Exams have been administered.
Both Physics C courses must also feature a hands-on laboratory component that mirrors a semester-long introductory college physics lab. A minimum of 20 percent of instructional time should be dedicated to hands-on experiments. Each student needs to keep a lab notebook or compile a portfolio of lab reports.
Schools need to ensure that every student has a calculus-based, college-level textbook for use both inside and outside the classroom, supplemented as necessary to meet curricular requirements. Lists of acceptable textbooks are linked from the Physics C course home pages on the AP Central website.
