Every pair of masses attracts. Newton's law says the pull is proportional to each mass and falls off with the square of their separation. Change the masses and the distance, and watch the force, and notice how quickly it weakens as the masses move apart.
MissionSet the masses, then predict what happens to the force F if the separation r is doubled.Streak 0Best 0
If the separation r is doubled with the masses unchanged, the force F becomes:
separation r4.0 × 10⁷ m
gravitational force F = Gm₁m₂ / r²1.7e20 N
The pull is equal and opposite on both masses. Halving r multiplies F by four; doubling r divides it by four.
