What you learn in Theory:
The nuclear force (or nucleon–nucleon interaction or residual strong force) is the force between two or more nucleons. It is responsible for binding protons and neutrons into atomic nuclei. The energy released by such binding causes the masses of nuclei to be less than the total mass of the protons and neutrons which form them; this is the energy used in nuclear power and nuclear weapons.
What you learn in Practice:
Nuclear forces are very weak compared to direct gluon forces ("color forces" or strong forces) inside nucleons and the nuclear forces extend only over a few nuclear diameters, falling exponentially with distance.
