If a body is thrown up in the air such that it deviates from simple one dimensional motion, it is termed a **projectile**. The analysis of motion associated with a projectile is known as **projectile motion** The path followed by a projectile is called its trajectory, which is directly influenced by gravity.

The initial velocity *v*_{0} can be written as

*v*

_{0x}and

*v*

_{0y}can be found if the angle Î¸

_{0}is known:

Since there is no acceleration in the horizontal direction, the horizontal component of the velocity remains unchanged throughout the motion.

The vertical motion is the motion of a particle in free fall. Equations for free fall apply. For example, . Other useful equations for the vertical y-axis are , and .

Eliminating t between the following two equations, and , we obtain the equation of the path (the trajectory) of the projectile:
