Gravitational Force: Tripling Distance - Factor 3 or 6?

Click For Summary
SUMMARY

When the distance between two objects is tripled, the gravitational force decreases by a factor of 9. This conclusion is derived from Newton's law of gravitation, which states that gravitational force varies inversely with the square of the distance between the objects. Therefore, if the distance is multiplied by 3, the force is divided by 3 squared, resulting in a decrease by a factor of 9.
