Consider a projectile thrown with velocity $u$ making an angle $\theta$ with the horizontal.
Velocity $u$ is resolved into two perpendicular components i.e. $x$ and $y$ directions.
We will write all the information about the projectile motion for horizontal and vertical direction in two separate columns.
| Horizontal motion | Vertical motion |
| ${u_x} = u\cos \theta $ | ${u_y} = u\sin \theta $ |
| ${a_x} = 0$ | ${a_y} = - g$ |
