F=mgh?

I would have used this but I noticed it was the same equation for gravitational potential energy (or just potential energy)...So I thought I would ask you all after failing to find it online.

I suspect you meantIs theforcedone on a lifted object equal the weight of the object in newtons times the height lifted?

Yes, the work you must do to lift an object equals the increase in gravitational potential energy.F=mgh?

So I thought I would find Ke at the bottom.

[tex]\sum w=\Delta ke[/tex]

W=F.d

So I want to know if F=mgh

:)

If I am completely full of crap and doing it wrong please tell me

No, F = mg (the weight). (Assuming you are doing the minimum work to overcome gravity.)W=F.d

So I want to know if F=mgh

So W = Fd = mgh.
