In physics, a coupling constant or gauge coupling parameter (or, more simply, a coupling), is a number that determines the strength of the force exerted...

to the square of the coupling constant for a charged particle to the electromagnetic field. There are analogous coupling constants that give the interaction...

of each coupling constant also has a sign, and coupling constants of comparable magnitude often have opposite signs. If the coupling constant between...

The gravitational constant is an empirical physical constant involved in the calculation of gravitational effects in Sir Isaac Newton's law of universal...

A constant-velocity joint (also called a CV joint) is a mechanical coupling which allows the shafts to rotate freely (without an appreciable increase...

In a quantum field theory, a coupling constant and a charge are different but related notions. The coupling constant sets the magnitude of the force...
