Wondering where the distance formula from acceleration due to gravity comes from

Pretty much like the title says. I'm having a hard time finding where the formula: d=1/2gt^2 comes from. Any help would be greatly appreciated.

If a=g, then integrate twice with respect to time !!

That's almost right. When you integrate twice you pick up two arbitrary constants of integration. To really derive the formula you would have to solve the following initial value problem:

[tex]\frac{d^2y}{dt^2}=-g[/tex]

[tex]y(0)=0[/tex]

[tex]y'(0)=0[/tex].
