Quizplus · Accepted Answer

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