This study guide covers free body diagrams (FBDs) and their application to uniform circular motion. It explains how to draw and interpret FBDs, emphasizing the importance of the coordinate system and including common forces like gravity, tension, friction, and normal force. The guide uses a roller coaster case study to illustrate FBDs at different points in a loop, highlighting the relationship between normal force and apparent weight. Finally, it provides practice questions and exam tips focused on applying Newton's Second Law in circular motion scenarios.
