- The weight of an object mg is the gravitational force between it and Earth. Substituting mg for F in Newton’s universal law of gravitation gives mg = GmM r2, where M is the mass of the object, M is the mass of Earth, and r is the distance to the center of Earth (the distance between the centers of mass of the object and Earth).

Substituting mg for \(F\) in Newton’s universal law of gravitation gives \[mg = G\dfrac{mM}{r^2}, \] where \(m\) is the mass of the object, \(M\) is the mass of Earth, and \(r\) is the distance to the center of Earth (the distance between the centers of mass of the object and Earth).
Sep 23, 2024 · In Newton’s law of universal gravitation, the attractive force between two objects (F) is equal to G times the product of their masses (m1m2) divided by the square of the distance between them (r2); that is, F = Gm1m2 / r2. The value of G is (6.6743 ± 0.00015) × 10 −11 m 3 kg −1 s −2.
