  1. Universal Gravitation constant is a unit conversion factor for
    Force=G m1*m2/r^2. The value of G depends on what system of units you are using.
    if one looks at force per mass, then we have a new term...
    force/mass2=G*M1/r^2
    this force/mass depends on distance from the prime mass m1. Force/mass is called gravitational field intensity, in newtons per kilogram. The value of it depends on the gravitational mass m1, and distance from it.
    Now in units
    force/mass also equals the acceleration due to gravity, which on the Earth's surface is 9.8m/s^2, and the gravitational field constant is 9.8N/kg

    :(note: force/mass=mass*a/mass= a which on Earths surface is "g". Honestly, I prefer calling it graviational field constant g, 9.8 N/kg
