Objects that are moving at an angle up or down a ramp have two parts to their speed.  Part of their speed is moving forward (horizontal) at a constant rate and part of their speed is moving up or down(vertical).   Because of gravity the vertical speed is either speeding up (on a down ramp) or slowing down (on an up ramp), and this is called acceleration.  In motion problems of this type it is assumed that the horizontal part of the speed and the vertical part of the speed are independent of each other. So the horizontal speed does not affect the vertical speed, and vice-versa.
