  • 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
  • Gravity - Math is Fun
    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: Gravitation - Physics LibreTexts
    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
