Gravitational Mysteries Unveiled

What does Newton's Universal Law of Gravitation state?

• Every object in the universe attracts every other object with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

• Objects with mass repel each other with a force that decreases as the distance between them increases.

• Gravity is a force that only affects objects on Earth.

• The force of gravity is the same on all objects, regardless of their masses.
