Here's why:

* Strong nuclear force: This force binds protons and neutrons together within the nucleus of an atom. It's incredibly strong, but it only acts over extremely short distances (about the size of the nucleus).

* Electromagnetic force: This force governs the interactions between electrically charged particles, including magnetism. It operates over a much wider range than the strong force, and can even act at distances much larger than the size of atoms.

* Weak nuclear force: This force is responsible for certain types of radioactive decay, and it also operates over very short distances.

* Gravitational force: This force acts between any two objects with mass, and its range is infinite.
