This equation deals with a projectile's maximum height above ground level. This is also one of the simplest equations that is used for a projectile's motion:

The maximum height is the initial velocity squared multiplied by the sin of the angle
measure squared divided by two times the acceleration of gravity (*g*). This equation
can be referred to as a "plug and chug" equations, as *some* physicists like to
say. Like so many other equations in this section, just plug the numbers in, do the math, and move on.
