Definition of nuclear force in English:

nuclear force


  • A strong attractive force between nucleons in the atomic nucleus that holds the nucleus together.

    • ‘The nuclear force is attractive and stronger than the electrostatic force, but it has a finite range.’
    • ‘A Grand Unified Theory is the greatest goal of physics and would unify the four fundamental forces of nature; electromagnetism, the strong and weak nuclear forces and gravity.’
    • ‘This resonance was due to a delicate balance between the strong nuclear force and the repulsive electromagnetic force in samarium.’
    • ‘Quarks are bound together by the strong nuclear force to form protons and neutrons in atomic nuclei, while the electromagnetic force holds electrons in orbits around the nucleus.’
    • ‘In addition to incorporating gravity in a quantum theory, string theory also attempts to combine the four forces of nature - the strong and weak nuclear forces, electromagnetism and gravity - into one unified theory.’
