When an object experiences uniform circular motion, the direction of the net force is
A) in the same direction as the motion of the object.
B) in the opposite direction of the motion of the object.
C) is directed toward the center of the circular path.
D) is directed away from the center of the circular path.
E) is dependent on the speed of the object.

Question

Quizplus · Accepted Answer

When an object is moving in uniform circular motion, it is constantly changing direction. As a result, there must be a force acting on the object to cause it to turn. This force is called the centripetal force and is always directed toward the center of the circular path. Therefore, choice C is the correct answer. Choices A and B are incorrect because the net force is perpendicular to the motion of the object, not in the same or opposite direction. Choice D is incorrect because there is no force directed away from the center of the circular path. Choice E is incorrect because the direction of the net force is independent of the speed of the object.
