Strong nuclear force: Unlike gravity and electromagnetism, the strong nuclear force is a short distance force that takes place between fundamental particles within a nucleus. It is charge independent and acts equally between a proton and a proton, a neutron and a neutron, and a proton and a neutron.
Strong nuclear force: Unlike gravity and electromagnetism, the strong nuclear force is a short-range force that occurs between fundamental particles within an atomic nucleus. It is charge-neutral and interacts equally with a proton-proton pair, a neutron-neutron pair, and a proton-neutron pair.
