This study guide covers contact forces in AP Physics 1, including: tension, normal force, friction (static and kinetic), and spring force. It explains how to draw free-body diagrams and provides key equations like the normal force on an incline, Hooke's Law, and friction equations. Example problems and practice questions are included, with a focus on inclined plane problems and exam strategies.
