This document defines and provides examples of uniform circular motion (UCM). UCM occurs when an object moves in a circular path at a constant speed. Centripetal force is the force directing an object towards the center and causing UCM by overcoming the object's inertia. Examples include a car turning a corner, a person on a spinning ride, a ball on a string, and satellites orbiting bodies. The document also provides steps for solving UCM problems using formulas for centripetal force, centripetal acceleration, and velocity, demonstrating the process through a sample problem of calculating the centripetal force on a plane circling a radius.
