what is newtons law of universal gravitation equation. The law of universal gravitation. Newtons law of universal gravitation states that two bodies in space pull on each other with a force proportional to their masses and the distance between them.
Every point mass attracts every single other point mass by a force pointing along the line intersecting both points. It is talked about in Isaac Newton s Philosophiae Naturalis Principia Mathematica. Comparison of Coulombs law and Newtons law of gravitation The electrical force between two charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
The universal gravitation equation thus takes the form.
The value of force Fg is the same for both the masses m1 as well as m2. Every point mass attracts every single other point mass by a force pointing along the line intersecting both points. Derivation of Newtons Universal Law of Gravitation based upon Keplers equations Sir Isaac Newton 1643 a 1727 Of course planets do not accelerate and fall into their center bodies due to a countervailing centrifugal force and Newtons Law of Inertia. In modern language the law states.
