1. Strong Nuclear Force: This is the strongest force in the universe and operates at the subatomic level, holding the nucleus of atoms together.
2. Electromagnetic Force: This force is responsible for interactions between electrically charged particles and is responsible for phenomena like electricity, magnetism, and light.
3. Weak Nuclear Force: This force is responsible for radioactive decay and is weaker than the strong force but stronger than gravity.
4. Gravitational Force: This is the weakest of the four fundamental forces but acts over the longest distances. It is responsible for the attraction between objects with mass.
These four forces are responsible for everything we see and experience in the universe, from the formation of galaxies to the interactions between atoms.
