The implication for the strong force coupling constant is that it drops off at very small distances. Analysis of the coupling constant with quantum chromodynamics gives an expression for the diminishing coupling constant: Coupling constants for fundamental forces This phenomenon is called " asymptotic freedom" because the quarks approach a state where they can move without resistance in the tiny volume of the hadron. The force isĪnother quantity with those dimensions which occurs naturally in the interaction of radiation with matter isĪ dimensionless constant which characterizes the electromagnetic force is The strength of the electromagnetic force can be related to the force between two electrons given by Coulomb's law. This coupling constant is also called the "fine structure constant" since it shows up in the description of the fine structure of atomic spectra. It appears naturally in the equations for many electromagnetic phenomena. Coupling constants for fundamental forces
