This study guide covers Coulomb's Law (including the formula, key ideas, and common mistakes), Free-Body Diagrams (FBDs) (including how to draw them and key points), and practice questions involving both concepts. It emphasizes the importance of understanding net force, equilibrium, and the relationship between charge, distance, and force. The guide also provides exam tips and high-priority topics for the final exam.
