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). This change in velocity indicates the presence of acceleration, known as centripetal acceleration, directed towards the center of the circular path. Therefore, the car's acceleration is not zero, its inertia is not zero (inertia is a property of matter that indicates resistance to changes in motion), and its velocity is not zero since it is moving.
