How does gravity affect the two components of projectile motion?

Projectile motion contains a horizontal (x) component, and a vertical (y) component. It is important to note that the x component, negating friction, is a constant velocity. Gravity only plays a part in the y component, where a = -9.8 m/s/s or a = -32 ft/s/s.
