Universal Gravitation
Every particle in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
Inverse Square Law
Gravity weakens with the square of distance - double the distance, force becomes 1/4.
Mass Proportionality
Force is directly proportional to the product of the two masses.
Universal Constant
G = 6.674 × 10⁻¹¹ N⋅m²/kg² - the same everywhere in the universe.
