Universal Gravitational Constant

Definition

The universal gravitational constant, denoted as G, is a fundamental physical constant that determines the strength of the gravitational force between two objects. It appears in Newton's law of universal gravitation and has a value of approximately 6.67430 x 10^-11 N(m/kg)^2.
