A PARTICLE WHEN GIVEN A VELOCITY AT AN ARBITRARY ANGLE MADE WITH THE HORIZONTAL SURFACE IS CALLED PROJECTILE, THE PATH FOLLOWED BY PARTICLE IS PARABOLA AND THE MOTION OF PARTICLE IS CALLED PROJECTILE MOTION
PROJECTILE MOTION IS TWO DIMENSION MOTION.

A 2d motion...which can be traced 
A projectile is an object upon which the only force acting is gravity. There are a variety of examples of projectiles. An object dropped from rest is a projectile (provided that the influence of air resistance is negligible). An object that is thrown vertically upward is also a projectile (provided that the influence of air resistance is negligible). And an object which is thrown upward at an angle to the horizontal is also a projectile (provided that the influence of air resistance is negligible). A projectile is any object that once projected or dropped continues in motion by its own inertia and is influenced only by the downward force of gravity.
