About Universal Gravitation
Newton's Discovery
Newton discovered that every object with mass attracts every other object. The force is proportional to the product of the masses and inversely proportional to the square of the distance between them.
Inverse Square Law
Gravity follows an inverse square law: doubling the distance reduces the force to one-quarter. This is why distant planets experience much weaker solar gravity.
