Uniform Circular Motion

Game da

How can the motion of an object in a circle at a constant speed be described? Is such an object accelerating or not? If there is an acceleration, then what direction is it and why does it not change the object's speed? How does a change in mass, speed, or radius of the circle affect quantities such as the acceleration and net force? Explore these questions and build the foundation for further studies with the Uniform Circular Motion Interactive.
