... change in velocity (velocityf – velocityi) and its acceleration both have positive values. When an object moves in one dimension (along a straight line) in the positive direction, and its velocity increases over time (it speeds up), its acceleration is positive. Now imagine that same car slowing d ...

Newton`s 1st Law of Motion
... due to the motion of the train. As stated in the first law, the ball has a tendency to maintain this horizontal motion because there is no external unbalanced force on it. It therefore comes back to the table very nicely because it and the table have had the same fixed horizontal speed. (Why doesn't ...
