Gravitational Constants

The gravitational constant, often symbolized as \(G\), is a fundamental number in physics that quantifies the strength of gravity—the force pulling objects toward each other. It helps us understand how planets stay in orbit, why objects fall to the ground, and how celestial bodies interact over vast distances. Essentially, \(G\) sets the scale for gravity's influence in the universe, serving as a key component in Einstein's equations of general relativity and Newton's law of universal gravitation. Its value is very small, indicating that gravity is a relatively weak force compared to other fundamental forces.
