This web page is an interactive physics homework problem relating to circular motion. A simulation depicts a ball on a string being whirled at constant speed. Given mass of the ball and tension in the string, students are asked to find the speed. The user has options to view an author-created free-body diagram and coordinate system. Explicit help is provided to find a solution by applying Newton's Second Law. This item is part of a collection of similar simulation-based activities developed for students of introductory physics.
