Page Uniform Circular Motion Uniform Circular Motion New Topic Question : A car drives around a circular track at a constant speed (say 30 mph). Is the velocity of the car constant? The speed is constant, this is true. However, the velocity , which involves both magnitude and direction , is not constant, since the direction is continually changing. Since velocity is not constant, the car is accelerating .
