The Universal Gravitational Constant

The Universal Gravitational Constant, denoted as G, is a fundamental value that measures the strength of gravity between objects. It appears in Newton's law of universal gravitation, which states that every two objects attract each other with a force proportional to their masses and inversely proportional to the square of the distance between them. G helps quantify this force, ensuring accurate calculations of gravitational interactions across the universe, from planets orbiting stars to galaxies moving through space. Its precise value is essential for understanding the behavior of celestial bodies and the structure of the cosmos.
