Newtons universal constant

  1. Aug 21, 2009 #1
    newtons universal constant is very complicated due to that i am new to modern earth science i searched on the net and the results were countless here is the common answer
    1-G=6.67*10(squared negative 11)m(cubed)kg(squared negative 1)s(squared)
    someone please tell me what all this means and how to use it?
    thank you all!

    It is constant which determines how strong gravity is.

    Newton's law of gravity says that the force of gravity acgting between two masses is equal to the the product of the two masses divided by the square of the distance between them multiplied by a constant. G is that constant.

    This gives you the formula:

    [tex]F_g = \frac{GMm}{d^2}[/tex]

    The value for G given in your post is what you use if M and m are measured in Kg and the distance between them is measured in meters. The answer will be in Newtons.

    There's a reason you have very strange units for G. The purpose off all the units is to make everything cancel out and give you a force in the end.
