I am a little confused on Newtons Seconds Law in Two dimensions. I know that when acceleration is zero that the net force in both the x and y-directions becomes zero. Is that because when acceleration is zero there's no net force?

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!
