Newton's universal law of gravitation says that the force acting upon (and therefore the acceleration of) an object toward Earth should be inversely proportional to the square of …

3.3: Newton's Universal Law of Gravitation

Newton's universal law of gravitation relates the gravitational force to mass and distance: Fgravity = GM1M2 R2 F g r a v i t y = G M 1 M 2 R 2. The force of gravity …

2.9: Newton's Universal Law of Gravitation

Stated in modern language, Newton's universal law of gravitation states that every particle in the universe attracts every other particle with a force along a line joining them. The force is directly proportional to the product of their masses and inversely …
