Strong interactions, also known as the strong nuclear force, are one of the four fundamental forces of nature, responsible for binding protons and neutrons in atomic nuclei. They are mediated by particles called gluons and operate over very short distances, overcoming the electromagnetic repulsion between positively charged protons.

Strong interactions

The strong nuclear force is the fundamental interaction responsible for holding atomic nuclei together, overcoming the electromagnetic repulsion between protons. It acts over very short ranges, approximately the size of an atomic nucleus, and is the strongest of the four fundamental forces in nature.

Gluons are elementary particles that act as the exchange particles for the strong force between quarks, which are the building blocks of protons and neutrons. They are massless, carry a color charge, and are responsible for binding quarks together to form hadrons, such as protons and neutrons, in atomic nuclei.

Electromagnetic repulsion is a fundamental force that occurs when two like-charged particles or objects repel each other due to their electric fields. It is one of the four fundamental forces of nature and plays a critical role in phenomena ranging from atomic interactions to macroscopic systems like magnets and electric circuits.
