Every object in the universe attracts every other object with a force along a line joining them. Universal Gravitation Learn about Newtons Law of Universal Gravitation. It is talked about in Isaac Newton s Philosophiae Naturalis Principia Mathematica.
Here G is the proportionality constant.
Where F F represents the force in Newtons M M and m m represent the two masses in kilograms and r r represents the separation in meters. The gravitational constant denoted by the letter G is an empirical physical constant involved in the calculation of gravitational effects in Sir Isaac Newtons law of universal gravitation and in Albert Einsteins general theory of relativity. Newtons law of universal gravitation is a general physical law derived from practical observation by Newton. Fg G x m1 x m2 r2 The formula that determines the amount of gravitational force applied by one object on another.
