In physics, the motion of a projectile can be broken down into two components: horizontal and vertical. In most cases, the vertical component is the motion caused by gravity acting on the object. For every object, gravity causes a constant acceleration towards the Earth at a rate of g=9.8 m/s2. Horizontal motion is the movement of a projectile across a horizontal plane based on the force acting on it. Across short distances, the vertical and horizontal motions of the projectile are perpendicular to and independent of each other. source from link http://www.wisegeek.com/in-physics-what-is-horizontal-motion.htm
