D. A skateboard moves 2 meters per second.
Answered by GPT 3.5
Yes, I am confident that the correct answer is D. A skateboard moves 2 meters per second. Velocity is a vector quantity that includes both speed and direction. In this case, the skateboard moving 2 meters per second specifies both its speed (2 meters per second) and its direction of motion.

C. Direction
Answered by GPT 3.5
I apologize for the confusion. The correct answer is D. Position. As the car travels around the roundabout, its position relative to a reference point (such as the center of the roundabout) is constantly changing. The speed, velocity, and direction may vary as the car accelerates or decelerates, but the position is constantly changing.

Apologies for the incorrect response again. You are right, the correct answer is B. Velocity. As the car travels around the roundabout, its speed may change as it accelerates or decelerates, its direction may change as it turns, but the velocity remains constant as long as the magnitude and direction of its motion remain unchanged.
