noun

Definition of STRONG FORCE

:  a fundamental physical force that acts on hadrons and is responsible for the binding together of protons and neutrons in the atomic nucleus and for processes of particle creation in high-energy collisions and that is the strongest known fundamental physical force but acts only over distances comparable to those between nucleons in an atomic nucleus —called also strong interaction, strong nuclear force — compare electromagnetism 2a, gravity 3a(2), weak force

First Known Use of STRONG FORCE

strong force

noun    (Concise Encyclopedia)

Fundamental force acting between elementary particles of matter, mainly quarks. The strong force binds quarks together in clusters to form protons and neutrons and heavier short-lived particles. It holds together the atomic nucleus and underlies interactions among all particles containing quarks. In strong interactions, quarks exchange gluons, carriers of the strong force, which are massless particles with one unit of intrinsic spin. Within its short range (about 1015 m), the strong force appears to become stronger with distance. At such distances, the strong interaction between quarks is about 100 times greater than the electromagnetic force.
