Uniform Circular Motion

The Uniform Circular Motion Interactive provides the learner with an interactive, variable-rich environment for exploring principles and relationships related to moving in a circle at a constant speed. Learners can manipulate the radius of the circle, the speed of the object and the mass of the object and investigate the effect upon the acceleration and net force. Velocity and acceleration vectors can be displayed for the moving object.
