The famous force due to gravity formula is an extension of Newton's second law, which states that a mass subjected to an outside force will experience acceleration: F = ma. If G, g and r are known then a reverse calculation will give an estimate of the mass of the Earth. Particles consist of standing waves of energy, made of in-waves that convert to out-waves. We all know what gravity does – drop a bowling ball on your foot and you surely know the answer. But gravity has still been used to uncover monumental findings.

In the absence of other forces, two particles would be attractive due to the rule that particles move to minimize wave amplitude, which is now lower between two particles. There was a problem. No matter the size of an object, it has a gravitational force that extends through all space. Cavendish built what’s known as a torsion balance, attaching two small lead balls to the ends of a beam suspended horizontally by a thin wire. Comparing the two formulas it is seen that: So, to find the acceleration due to gravity at sea level, substitute the values of the gravitational constant, G, the Earth's mass (in kilograms), m1, and the Earth's radius (in metres), r, to obtain the value of g: This formula only works because of the mathematical fact that the gravity of a uniform spherical body, as measured on or above its surface, is the same as if all its mass were concentrated at a point at its centre. Thus, to estimate the number of nucleons (Q) in a group, or large body, the following is equation is used. Traveling, longitudinal waves that convert some of their energy (amplitude) to magnetic spin as it passes through a body. And when the net force is greater on one side of an object, it will move in the direction of the force (amplitude is higher on one side and it seeks the direction of minimal amplitude). His theory of general relativity showed that gravity arises from the curvature of space-time, meaning that even rays of light, which must follow this curvature, are bent by extremely massive objects. Gravity is a result of traveling, longitudinal waves that are absorbed by particles.

Einstein’s theories were used to speculate about the existence of black holes — celestial entities with so much mass that not even light can escape from their surfaces.

The surface of the Earth is rotating, so it is not an inertial frame of reference.At latitudes nearer the Equator, the outward centrifugal force produced by Earth's rotation is larger than at polar latitudes.

This method was used by Henry Cavendish.
