Definition of law of universal gravitation and derivation and diagram
  • 1 answers

Yogita Ingle 4 years ago

Newton’s conclusion about the magnitude of gravitational forces is summarized symbolically as

F = Gm1m2/ r2

where,

  • F is the gravitational force between bodies
  • m1 is the mass of one of the objects
  • m2 is the mass of the second object
  • r is the distance between the centres of two objects
  • G is the universal gravitational constant

The constant proportionality (G) in the above equation is known as the universal gravitation constant. The precise value of G was experimentally determined by Henry Cavendish in the century after Newton’s death. The value of G is found to be G = 6.673 x 10-11 N m2/kg2.
