AP Physics C: Mechanics
Ten units, from the calculus foundation through gravitation, each with worked problems grouped by topic. It's a straight line — start where your class is, or work it from the top.
Unit 0
Intro to Calculus
Derivatives, integrals, and graphs — the math foundation everything else builds on.
Coming soon
Unit 1
Vectors
Vector algebra, dot and cross products. The language all of AP Physics C depends on.
3 problems
Unit 2
Kinematics
Motion in one and two dimensions, projectiles, and the calculus definitions of velocity and acceleration.
Coming soon
Unit 3
Newton's Laws of Motion
Free-body diagrams, friction, tension, and the resistive-force differential equations AP actually asks for.
Coming soon
Unit 4
Circular Motion
Centripetal acceleration, banked curves, and non-uniform circular motion.
Coming soon
Unit 5
Work, Energy & Power
Work as an integral, conservative forces, potential energy functions, and energy-diagram reasoning.
Coming soon
Unit 6
Center of Mass
Center of mass position and motion, collisions, impulse, and momentum conservation.
Coming soon
Unit 7
Rotational Motion
Torque, moment of inertia, rotational kinematics, and rolling without slipping.
Coming soon
Unit 8
Simple Harmonic Motion
SHM from the differential equation up: springs, pendulums, and energy in oscillation.
Coming soon
Unit 9
Gravitation
Newton's law of gravitation, orbital mechanics, and gravitational potential energy.
