Quick question on force

  1. Aug 15, 2009 #1
    1. The problem statement, all variables and given/known data

    when there are like two objects moving farther away from each other, is the force bigger or smaller when they are closer together?

    is it bigger? cuz the gravitational force of attraction is pulling them together?

    So the force is given by F=GMM/r2. So as r increases what happens to F?

    ooo it gets smaller beacuase there is a larger number diving the GMM. so then if the mass gets bigger, but the distance between gets smaller, then the force will increase right?

    That is the idea here.
