Newton's first law of motion states that an object will keep a constant velocity unless acted upon by an unbalanced force.

To test this statement, Martin rolled a ball on a long, level street. The ball did not bump into any object, but it eventually came to a stop. How is this possible?
	A. 	Newton's first law of motion only holds true in space, not on Earth.
	B. 	Every moving object must come to a stop because energy cannot be destroyed.
	C. 	Martin did not roll the ball hard enough, which caused the ball to eventually stop rolling.
	D. 	The unbalanced force that caused the ball to stop was friction.

friction caused the ball to stop.. in other words there are losses associated with any kind of work.. here friction causes the ball to stop
