Answer
The strong force, studied in quantum chromodynamics, is the fundamental force responsible for binding subatomic particles called quarks together to form protons and neutrons. It is the strongest of the four fundamental forces, acting over very short distances within the nucleus of an atom. The strong force is mediated by particles called gluons, which carry the force between quarks.
