Study Guide Overview
This study guide covers circular motion and gravitation, focusing on vector fields, fundamental forces (especially gravity), Newton's Law of Gravitation, gravitational fields and acceleration, and the difference between inertial and gravitational mass. It also explains centripetal acceleration and force, free-body diagrams for circular motion, and applications including frames of reference and rotational kinematics. Practice questions and answers are included.
