What Is Uniform Circular Motion?

Objects that move in a circular route at the same speed through multiple revolutions experience uniform circular motion. For this to occur, acceleration of the object on the circular path is dependent upon velocity and the radius of the circle.

Newton’s second law of motion explains that force acts upon an object for acceleration – such as circular motion – to occur. Changes in acceleration affect the direction and size of the circular motion, but not the velocity of the object. An object that moves in a circular motion requires centripetal force. The speed of the object in uniform circular motion is a product of the radius and the time it takes an object to complete one revolution.
