Newtonian Gravity questions

  1. Mar 23, 2008 #1
    Before I inundate you with various elementary problems I'm facing, I need help with the concept.


    So Fgrav is in units of Newtons, correct? How would one convert that to m/s?

    Gravity is just a force an object with mass experiences, which can be translated to acceleration with Newton's 2nd Law, F=ma. It has nothing to do with velocity (which has units m/s). However you can turn it into units of m/s^2, which is the units of acceleration with the above mentioned law: a=F/m, therefore:

    Where M is the mass of the object that is creating the gravitational field, not the "accelerating object".
