This study guide covers friction in AP Physics C: Mechanics, including kinetic friction (for sliding surfaces) and static friction (for surfaces at rest). It explains the calculation of frictional forces using coefficients and normal force, and how friction applies to inclined planes, work/energy, and circular motion. Practice questions and exam tips are also provided.
