The gravitational constant is an empirical physical constant involved in the calculation of gravitational effects in Sir Isaac Newton's law of universal gravitation and in Albert Einstein's theory of general relativity.
Newton's law of universal gravitation states that every particle attracts every other particle in the universe with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
Nov 7, 2023 · Sir Isaac Newton's Law of Universal Gravitation helps put the laws of gravity into a mathematical formula. And the gravitational constant is the "G" in that formula.

This article is about Kepler's laws of planetary motion which describe the motions of planets in the solar system that were derived by German astronomer Johannes Kepler with later contributions from Sir Isaac Newton for his law of gravitation. It also mentions how these laws apply not only to gravitational but also other inverse-square-law forces.
The article is about the laws of gravitation.
Kepler’s three laws describe the motions of planets in the solar system, including elliptical orbits and angular momentum.
A radius vector joining any planet to the Sun sweeps out equal areas in equal lengths of time.
The squares of sidereal periods are directly proportional to cubes of mean distances from Sun.
Laws apply not only to gravitational but also to all other inverse-square-law forces and electromagnetic forces within atom if allowance made for relativistic and quantum effects.

Sep 23, 2024 · In Newton’s law of universal gravitation, the attractive force between two objects (F) is equal to G times the product of their masses (m 1 m 2) divided by the square of the distance between them (r 2); that is, F = Gm 1 m 2 /r 2.

Stated in modern language, Newton’s universal law of gravitation states that every particle in the universe attracts every other particle with a force along a line joining them. The force is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
