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?

OpenStudy (holly00d1248):

A. Martin did not roll the ball hard enough, which caused the ball to eventually stop rolling. B. The unbalanced force that caused the ball to stop was friction. C. Newton's first law of motion only holds true in space, not on Earth. D. Every moving object must come to a stop because energy cannot be destroyed.

@shamim

OpenStudy (holly00d1248):

Is it B

OpenStudy (darkbluechocobo):

You sir are correct

OpenStudy (shamim):

Ya its B

OpenStudy (shamim):

Friction between ball nd road is oposit to the motion of ball

OpenStudy (shamim):

This frictional force eventually stop the ball

OpenStudy (shamim):

If frictional force was absent here, then the ball was going with uniform velocity. Never stop

OpenStudy (shamim):

For example, there is no friction in space. If the ball was moving in the space, it never stop
