Uniform circular motion describes an object moving at a constant speed in a circular path, caused by a force directed towards the center called the centripetal force. While velocity is always tangent to the circle, acceleration and centripetal force are always pointed towards the center, meaning the object is constantly accelerating even if its speed does not change. The equation for centripetal force is Fc=(m)(ac), where Fc is centripetal force, m is mass, and ac is centripetal acceleration.
