Effects of Minute Gravity

[googol]

Does anybody know an equation that will measure the force of gravity. I've seen one but I need one that will measure it in Newtons instead of making a general statement about it.

F=GmM/r^2

F is force, G is newton's constant of gravitation, m and M are the masses of the body, r is the distance between the center of the masses.

I already know that equation, it won't tell me the force in newtons though.

[OfficeShredder]

Yes, actually, GmM/r^2 is in newtons. Do you actually know this equation, or do you just want to think you do? Check the units of a newton, and of the equation, and see how they perfectly line up. It's not a coincidence

[googol]

Oh, I thought that equation was merely to understand gravity rather that to measure it.

So is F in newtons, M & m in Kg,and r in meters?

[OfficeShredder]

Yes. And G is in whatever units are needed to make F in newtons (if you google G you'll get the units and the actual value)

[googol]

Ok, I understand it now, and just for the fun of It i made a little program that will calculate it for you.
