strong force |
Also found in: Dictionary/thesaurus, Wikipedia | 0.06 sec. |
strong forceor strong nuclear forceFundamental 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 10−15 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. How to thank TFD for its existence?

Under normal conditions the potent color force keeps quarks and gluons tightly confined within the nuclear particles. Physicists have divided all the motions in the universe into the domains of four kinds of force: gravity, electromagnetism, the weak subatomic force and the strong subatomic force or color force. |
