Newton's Third Law and Free-Body Diagrams

This study guide covers force vectors, including their magnitude and direction, and how to represent them visually. It emphasizes free-body diagrams (FBDs) for analyzing forces and introduces common forces like weight, normal force, and friction. Newton's Laws of Motion, especially the second law (F=ma), are explained. The guide also covers force interactions, action-reaction pairs, and common force pairs like gravity and tension. Finally, it provides tips for the exam, highlighting the importance of FBDs, Newton's Laws, and calculating net force.
