Question

an object is moving in a circle at a constant speed. what is true about the objects velocity? a. the objects velocity is zero. b. the objects velocity is constant, but not zero. c. the objects velocity is identical to its speed. d. the objects velocity is changing.

Explanation:

Velocity is a vector quantity with both magnitude (speed) and direction. When an object moves in a circle at a constant speed, its speed remains the same but its direction is constantly changing as it follows the circular path. So the object's velocity is changing.

Answer:

D. The object's velocity is changing.
