Force of Gravity in terms of Density

wildkat7411 · Feb 8, 2010

Does anyone know the equation for the Force of Gravity in terms of density? I have been trying to plug in the equatin for the density of a sphere into Newtons Gravity formula and keep hitting dead ends. And if you can show me the math and reasoning behind it please.

I'm not sure what you are looking for. The only reason to use density would be to find the mass when you only have the density and volume of the body involved. In which case you calculate the mass from the given density and volume and plug that answer into the equation.
