The force that holds protons and neutrons together in the nucleus of an atom.

The force that holds protons and neutrons together in the nucleus of an atom. It's the strongest of the four fundamental forces of nature, but operates only over very short distances. Protons normally repel one another because of their electric charge, but when they are squeezed very close together, the strong force comes into play and overcomes this repulsion.
