Question

Quizplus · Accepted Answer

An object traveling in a circle at constant speed experiences an acceleration toward the center of the circle known as centripetal acceleration. This acceleration changes the direction of the velocity of the object without changing its magnitude, resulting in circular motion. Therefore, option D, "experiences an acceleration toward the center of the circle," is the correct choice.
