Formulas of Ch gravitational

Dear Studnet

The universal law of gravitation states that there is a force of attraction between two masses separated by some distance. The gravitational force between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.


Where, G is the universal gravitational constant, m1 and m1 are the masses separated by a distance r.

g = GM

Weight: The force of attraction of the earth on the object is known as the weight of the object. Its S.I. unit is Newton.
          W = m × g
