Horizontal Projectile Motion is a special case of projectile motion, in which a projectile is thrown horizontally resulting in a curved trajectory due to the gravity acting on the projectile.

It can be analysed into two separate motions, a uniform linear motion on the x-axis and a free fall on the y-axis.

OX-axis: The motion is uniform linear with velocity Vx.The equations that describe its movement on the direction (x):

         $x = V_{x}t$


OY-axis: The projectile does a free fall.The equations that describe its movement on the direction (y):

         $V_{y} = g t$

         $y = 1/2 g t^{2}$


At every moment the projectile's speed is: $\vec{v} = \vec{v_{x}} + \vec{v_{y}}$

The displacement of the projectile: $d = \sqrt{x^2 + y^2}$

We can assume that the motions happen independently, either simultaneously or successively, with each motion lasting for:

$t = \sqrt{\frac{2h}{g}}$
