Which of the following describes the net force on air moving in a circle at constant speed?

Question

Quizplus · Accepted Answer

When an object is moving in a circle at constant speed, there must be a centripetal force acting on it, directed toward the center of the circle. In the case of air moving in a circle, the centripetal force could be provided by a pressure gradient, with air at the outer edge of the circle experiencing greater pressure than air at the inner edge. The net force on the air will be in the same direction as the centripetal force, so the answer is inward toward the center of rotation (choice B).
