The document describes the four fundamental forces that govern interactions between matter: (1) the strong force that binds quarks together and holds protons and neutrons in the atomic nucleus; (2) the electromagnetic force that binds electrons to the nucleus and is responsible for chemical interactions; (3) the weak force that is involved in radioactive decay; and (4) the gravitational force that attracts all masses. It provides a table matching examples of interactions between different particles and molecules with the corresponding fundamental force.
