When a car travels around a circular track at constant speed, its direction is constantly changing, which means its velocity is changing (since velocity is a vector quantity that includes both speed and direction). This change in velocity over time means the car is accelerating, even though its speed (the magnitude of its velocity) remains constant. Therefore, its acceleration is not zero, and its velocity is not zero either.
