F = Gmm'/r^2
Does this explain the sum or total gravitational force between two bodies?

Miike012 said:Ok thank you.
Maybe you can help with this question as well...
During a jump off a diving board, is your apparent
weight (a) equal to your true weight, (b) slightly less
than your true weight, (c) slightly more than your true
weight, or (d) zero?
The answer is zero? I thought it would have been (b)
Miike012 said:Actually one last question also... Why do we use the gravitational constant G?
Is this only relevant to earth? therefore if I wanted to calculate the gravitational force of an object to mercury I would have to use another value that is not G?

If you held a bathroom scale against your feet during your jump, what do you think the scale would show as your weight?
Weight is what a scale measures. It measures the force placed upon it. On the moon you would weigh less.Miike012 said:So if I was listening to my self I should have actually said the weight would stay the same.
