The story of Isaac Newton discovering the laws of gravity by watching apples falling from a tree is probably just a myth He did do his work on gravity while at a farm, but that is about as much as can be proven

- What is gravity? - Live Science
Gravity is one of the four fundamental forces in the universe, alongside electromagnetism and the strong and weak nuclear forces Despite being all-pervasive and important for keeping our feet
- How does gravity work? - HowStuffWorks
The standard formula for the law of gravitation goes [source: UT]: Gravitational force = (G x m1 x m2) (d 2) where G is the gravitational constant, m1 and m2 are the masses of the two objects for which you are calculating the force, and d is the distance between the centers of gravity of the two masses

The average value is 9 80665 m s 2, but values are different around the world, such as Calcutta at 9 78548, London at 9 81599 and Tokyo at 9 79805 So most people just use 9 8 m s 2
- Gravity - Force, Physics, Theory | Britannica
Gravity - Force, Physics, Theory: The Newtonian theory of gravity is based on an assumed force acting between all pairs of bodies—i e , an action at a distance When a mass moves, the force acting on other masses had been considered to adjust instantaneously to the new location of the displaced mass That, however, is inconsistent with special relativity, which is based on the axiom that all

13 1: Prelude to Gravitation Our visible Universe contains billions of galaxies, whose very existence is due to the force of gravity Gravity is ultimately responsible for the energy output of all stars—initiating thermonuclear reactions in stars, allowing the Sun to heat Earth, and making galaxies visible from unfathomable distances
