	PowerPedia:Force - PESWiki
		Force is a vector quantity defined as the rate of change of the momentum of the body that would be induced by that force acting alone.
		The SI unit of force is the newton, while the English unit of force is the pound-force.
		Conservative forces are equivalent to the gradient of a potential, and include gravity, electromagnetic force, and spring force.

		Coulomb's law is a vector equation and includes the fact that the force acts along the line joining the charges.
		Coulomb's law describes a force of infinite range which obeys the inverse square law, and is of the same form as the gravity force.

	Coulomb's law - HighBeam Encyclopedia (Site not responding. Last check: 2007-10-20)
		Coulomb's law applies exactly only when the charged bodies are much smaller than the distance separating them and therefore can be treated approximately as point charges.
		When combined with principles of quantum physics, Coulomb's law helps describe the forces that bind electrons to an atomic nucleus, that bind atoms together into molecules, and that hold together solids and liquids.
		The law was deduced in 1785 by C. de Coulomb from experimental measures of the forces between charged bodies; the experiments were made using his torsion balance.

	Coulomb's law
		In physics, Coulomb's Law is an inverse-square law indicating the magnitude and direction of electrical force that one stationary, electrically charged substance of small volume exerts on another.
		When one is interested only in the magnitude of the force (and not in its direction), it may be easiest to consider a simplified, scalar version of the Law
		Among other things, this formula says that the magnitude of the force is directly proportional to the magnitude of the charges of each substance and inversely proportional to the square of the distance between them.

	QUANTUM GRAVITY
		Our initial postulate was that gravity is the result of the relative difference between the Coulomb force and the centripetal force within atoms, caused by the centrifugal inertia of the electron cloud, as established by the principles of relativity.
		This difference is a relative force that does not possess mass: after all the electrical charges are neutralized, we have a residual force representing an acceleration from the reference point of the nucleus.
		We have seen that, given the principles of relativity and due to the gravitational conditions of the atom, a small variation in the velocity of the electron unbalances the forces such that, when the point of reference is the proton, the Coulomb force is greater than the centripetal force.

		In physics, Coulomb's law is an inverse-square law indicating the magnitude and direction of electrostatic force that one stationary, electrically charged object of small dimensions (ideally, a point source) exerts on another.
		The formula to Coulomb's Law is of the same form as Newton's Gravitational Law: The electrical force of one body exerted on the second body is equal to the force exerted by the second body on the first.
		This formula says that the magnitude of the force is directly proportional to the magnitude of the charges of each object and inversely proportional to the square of the distance between them.

		The nuclear force has been at the heart of nuclear physics ever since the field was born in 1932 with the discovery of the neutron by James Chadwick.
		In recent years, experimenters have concentrated on the subtleties of the nuclear force, such as its charge dependence, the precise value of the πNN coupling constant, improved phase shift analysis, high-precision NN data, high-precision NN potentials, NN scattering at intermediate and high energies, and attempts to derive the nuclear force from QCD.
		This part of the force does not conserve orbital angular momentum, which is a constant of motion under central forces.

		In terms of SI base units, the coulomb is the equivalent of one ampere-second.
		The force with which two electrically charged bodies attract or repel one another depends on the product of the charges (in coulombs) in both objects, and also on the distance between the objects.
		For any two charged bodies, the coulomb force decreases in proportion to the square of the distance between their charge centers.

		Again, this is due to the spherical symmetry: the only preferred directions are radially inward or outward, and we associate those directions with the sign of the source.
		This force is of course equal to the Coulomb force; from this equation we can see that the units of the electric field are N / C. The notion here is that a charged particle has an influence independent of whatever forces are felt by other charges.
		Just as the Coulomb force is the gradient of the electrical potential energy, the electric field is the gradient of the electrical potential.

	Coulomb Force
		In the case of the electric "Coulomb" force, the magnitude is proportional to the product of the charges, and inversely proportional to the square of the distance between them.
		The force of gravity is very similar to the Coulomb force; the charges are now the masses of the objects which are gravitationally attracted, and the constant of proportionality ("Newton's Constant", equal to 6.673 x 10
		Note also that both the Coulomb and gravitational forces are vectors: therefore the superposition of two or more forces is equal to their linear sum.
