This study guide covers forces as vector quantities, including contact forces. It explains free-body diagrams as a tool for visualizing forces, emphasizing the representation of forces from the environment (gravitational force, normal force, tension, and applied forces) as vectors originating from the center of mass. It also highlights coordinate system selection and provides practice questions and exam tips.
