The Physics Classroom: Circular and Satellite Motion: Centripetal Force
Through illustrated examples and practice problems, students explore the centripetal force requirement. So for an object moving in a circle, there must be an inward force acting upon it in order to cause its inward acceleration.

The Physics Classroom: Circular and Satellite Motion: Newton's 2nd Law Revisited
In this interactive module, students use free-body diagrams, Newton's second law equation, and circular motion concepts to analyze a variety of physical situations involving the motion of objects in circles or along curved paths.
