Last week of Physics, one of the most important things I learned in class was the "Vegas Rule". The Vegas rule is: whatever happens on the x-axis, stays on the x-axis. This saying is also the same for the y-axis. What this means, is that the x and y axis of an object are independent and don't affect each other. For example, if I were to throw this pool stick horizontally on the x-axis with no force directed to the y-axis, the time it would take to fall would be the same as if I just dropped the pool stick directly from the same height. This is because what happens on the y-axis stays on the y-axis. Just because I would throw the pool stick horizontally on the x-axis, it doesn't affect the velocity, acceleration or anything dealing with the y-axis. Although it would be traveling on the x-axis, it would also be accelerating down the y axis with the same velocity as if it were directly dropped. The only difference is, the one being dropped is not traveling on the x-axis.
