What is the maximum height of a projectile?

A body when thrown vertically upward with some angle and velocity it possess a projectile motion.During this path the body/object reaches a certain maximum height and after that starts to fall downwards. This maximum height reached by the object is mathematically expressed as

$H=\frac{v_0^2{\sin }^2\theta }{2g}$ where $\theta$= angle with respect to the horizontal surface $v$=velocity and g=gravity
