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 on a horizontal circle. Given mass of the ball and tension in the string, students are asked to find the speed. 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. See Related Materials on this page for a link to the full index of simulations designed by this author to support first semester physics curriculum.
