question
Is there change in the force of gravity between two objects when their masses are doubled and the distance between them is also doubled?
answer
no
question
What would be the path of the Moon if somehow all gravitational forces on it vanished to zero?
answer
The moon’s path would be in a straight-line and not around the Sun and Earth
question
Is the force of gravity stronger on a crumpled piece of paper than on an identical piece of paper that has not been crumpled?
answer
The force of gravity is the same on both papers because it explains the Newton’s equation for gravitational force
