Which of the following statements BEST describes Newton’s second law of motion?         The object is either at rest or it moves with constant velocity when there is no net force acting on it.       The force acting on an object is equal to its mass times its acceleration.       An object with mass m subjected to a net force will have acceleration equal to the net force divided by its mass.

Newton's First Law of Motion

If a very smooth ball is rolled down an inclined surface with zero friction, the ball will continue to roll indefinitely for an infinite time, in an attempt to reach to the same height on the opposite hill!
