The AP Physics C course actually consists of two parts. The Mechanics portion (which is offered as a full-year course in some high schools, and as a semester-long course in others) includes units on kinematics, Newton’s Laws of Motion, Work, Energy, Power, Linear Momentum, Circular Motion, Angular Momentum, Oscillatory Motion, and Gravitation.
The second semester consists of units in Electricity & Magnetism, including electrostatics, conductors, capacitors & dielectrics, electric circuits, magnetic fields, and electromagnetism.
While there are distinct advantages to learning—either in a classroom or online—with a real physics teacher, there are a number of online references that can help assist in your learning.
