Newton’s Universal Law of Gravitation
Definition
Newton's Universal Law of Gravitation states that every particle attracts every other particle with a force directly proportional to their masses and inversely proportional to the square of their distance apart.
Analogy
Imagine two people playing tug-of-war with different strengths. If one person has more strength (mass) than the other, they will pull harder and closer together. Similarly, according to Newton's law, larger masses will have a stronger gravitational pull.
