Quizplus · Accepted Answer

When a car travels around a circular track at a constant speed, its direction changes continuously, which means its velocity is changing (since velocity is a vector quantity that includes both speed and direction).

Therefore, options A, B, and C are incorrect, making D the correct choice.
