The strength of the gravitational force depends on the gravitational constant.Any mass warps the fabric of space-time around itself and more the mass, the more the warping.
Gravitation constant was 1st accurately determined by Henry Cavendish in 1797 and it is an essential component of both Isaac Newton’s law of universal gravitation and Albert Einstein’s theory of general relativity.
Newton’s theory – The gravitational force between 2 objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
Einstein’s theory of general relativity – It states that space and time are relative, and all motion must be relative to a frame of reference.
Importance of G – The precise value of G is crucial to understand celestial mechanics and to determine the mass of celestial bodies.
