Relative Motion in Two Dimensions
... • When an object moves in a circle, the net force toward the center of the circle is called the centripetal force. • To analyze centripetal acceleration situations accurately, you must identify the agent of the force that causes the acceleration. Then you can apply Newton’s second law for the compon ...
