7: The Theory of Gravitation - The Feynman Lectures on Physics

Gravitation is a fundamental interaction in physics that governs the motion of objects across all scales, from falling apples to the expansion of the universe. While classical physics describes it as an attractive force, modern physics redefines it as the geometric curvature of spacetime. 1. Newton's Law of Universal Gravitation Gravitation (Physics Series)

: Every particle of matter 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 their centers. Mathematical Formula : 7: The Theory of Gravitation - The Feynman

Proposed in 1687, Newton’s model treats gravity as a "tug of war" between any two masses in the universe. Newton's Law of Universal Gravitation : Every particle

: If the distance between two objects doubles, the gravitational force between them is reduced to one-fourth of its original strength.

Fg=Gm1m2r2cap F sub g equals the fraction with numerator cap G m sub 1 m sub 2 and denominator r squared end-fraction Fgcap F sub g is the gravitational force, are the masses, is the distance between them, and is the universal gravitational constant (
