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):

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

At every moment the projectile's speed is:

The displacement of the projectile:

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