1. Strong Nuclear Force: This force holds the nucleus of an atom together, overcoming the electrostatic repulsion between protons. It is the strongest force in the universe, but it acts only over extremely short distances.
2. Electromagnetic Force: This force governs interactions between electrically charged particles. It is responsible for phenomena like magnetism, electricity, and light. It's weaker than the strong force, but it has an infinite range.
3. Weak Nuclear Force: This force is responsible for radioactive decay, where a neutron can decay into a proton, electron, and antineutrino. It is responsible for processes like nuclear fusion in stars and is much weaker than the strong force.
4. Gravitational Force: This force is the weakest of the four forces, but it is the force that holds the universe together. It acts between any two objects with mass and has an infinite range.
While gravity is the weakest force, its effect is significant over large distances due to the vast amount of mass in the universe.
