Homework Help: Gravitational force homework

  1. Nov 28, 2006 #1
    If the gravitational force between two massive bodies were measured and divided by the product of their masses, and then multiplied by the square of the distance between their centers of mass, what number would result?

    is it 9.8N?

    How did you get that number, show your work!

    No it isn't. What's the formula for gravitational force? And especially put in the units. You will easily see you aren't left with just N.

    G= 6.67 X 10-11 N/kg2/m2

    That's newtons graviational constant. What is the whole formula for gravitational force? hint: it contains the constant you mentioned.

    Gravity ISN'T calculated that way. And if it were, or if you used the correct formula, do you really think you would always get a single number, regardless of what those masses and distance are? Please go back and read the question again. What you have written is nonsense.
