1. Strong Nuclear Force: This is the strongest force, responsible for holding the nucleus of an atom together. It acts over extremely short distances, within the nucleus.

2. Electromagnetic Force: This force governs the interaction between electrically charged particles. It is responsible for phenomena like electricity, magnetism, and light. It has an infinite range, but its strength weakens with distance.

3. Weak Nuclear Force: This force is responsible for nuclear decay, such as beta decay. It is weaker than the strong force and acts over extremely short distances within the nucleus.

4. Gravitational Force: This is the weakest force but has an infinite range. It governs the attraction between any two objects with mass. It is responsible for the orbits of planets and the formation of stars and galaxies.
