What is gravity - all tech

Newton's law of gravitation is commonly said that every particle attracts every other particle in the universe with a force that is directly proportional to the product of their mass and inversely proportional to the square of the distance between their centers.  it happens.

  It is a general rule that each point mass attracts each point by the force acting along a line crossing two points.  Force is proportional to the product of two masses, and inversely proportional to the square of the distance between them.

  The equation for universal gravity is as follows:

F = G {\ frac {m_ {1} m_ {2}} {r ^ {2}}}

  Where F is the gravitational force acting between two objects, m1 and m2 are the masses of objects, r is the distance between their centers of mass, and G is the gravitational constant.

  The first test of Newton's theory of gravity among the public was the Cavendish experiment conducted in 1798 by the British scientist Henry Cavendish.  This occurred 111 years after the publication of Newton's Principia, and about 71 years after his death.

  Newton's law of gravity is similar to Coulomb's law of electric forces, which is used to calculate the magnitude of the electric force between two charged bodies.  Both are inverse-square laws, where the distance between forces is inversely proportional to the square.  The Coulomb's law consists of the product of two charges instead of the product of mass, and the Coulomb constant instead of the gravitational constant.

  Albert Einstein's theory of general relativity has been scrapped since Newton's law, but it is used in most applications as an excellent approximation of the effect of gravity.  Relativity is required when extreme accuracy is required, or when dealing with very strong gravitational fields, such as near extremely large and dense objects, or over short distances (such as Mercury's orbit around the Sun).  .

  Each system in the galaxy is, and possibly is, a divisor in the universe.  The push and pull of the gravitational force of objects is what keeps everything in space from colliding with each other.

  Since the force of gravity is directly proportional to the mass of the two interacting bodies, the more massive objects will attract each other with a larger gravitational force.  So as the mass of an object increases, the force of gravitational attraction between them also increases.  If the mass of any one object doubles, the force of gravity between them doubles.  If the mass of a single object is tripled, then the force of gravity between them is tripled.  If the mass of both the objects is doubled, then the force of gravity between them is quadrupled.
