What is the conceptual difference bet weight and m?

The strong nuclear force is a non-contact force described as strong since, for interactions involving sufficiently low energies, the strong interaction is the "strongest" of the four fundamental forces; its strength is 100 times that of the electromagnetic force, and several orders of magnitude greater than that of the weak force and gravitation. (These ratios are in fact figures of convenience; the fundamental figures vary dramatically according to the distances over which the forces are exerted. For example, the "weak" force really is roughly as strong as the electromagnetic force at the distances relevant to its effects, which are a small fraction of the radius of the nucleus of an atom.)
