This AP Physics C: Mechanics practice exam (print & digital versions included) has 40 multiple-choice questions covering all 7 units, plus all 4 free-response questions worth 10, 12, 10, and 8 points — a translational dynamics problem with friction, a ballistic pendulum combining momentum and energy, a disk pulley with hanging mass, and a mass-spring SHM problem. The study guide walks through all 7 units (kinematics, force/translational dynamics, work/energy/power, linear momentum, torque/rotati
