If the distance between two objects is tripled, by what factor will the
gravitational force between them change?

• Physics -

1/(3^2) = ?

That's called using the inverse square law.

• Physics -

but what is the 3^2 for? If the 3 is for the distance being tripled...what about the exponent 2?

• Physics -

Oh nvm, you mean

F = 1/d^2

Got it...thanks.

• Physics -

1/(3^2) = 1/9

Square the distance ratio and put it in the denominator

• Physics -

if the separation distance b/w two objects is tripled is increased by a factor of 3,then the force of gravitation is decreased by a factor of 6
