An overhead view showing a car moving along a circular path turning to the left (counter-clockwise). A dotted line extends from the car's original position, showing a straight-line path tangent to the circle. Inside the car, a small square represents the passenger. Arrows show the car's velocity vector pointing along the curve and an acceleration vector pointing toward the center of the circle on the left.
