1. Strong Nuclear Force
* Range: Extremely short, approximately 1 femtometer (10⁻¹⁵ meters)
* Description: The strongest force, responsible for holding protons and neutrons together in the nucleus of an atom. Its strength decreases rapidly with distance.
2. Weak Nuclear Force
* Range: Extremely short, even shorter than the strong force.
* Description: Responsible for radioactive decay, where a neutron can decay into a proton, electron, and antineutrino. This force is important for nuclear reactions within stars.
3. Electromagnetic Force
* Range: Infinite (theoretically)
* Description: Responsible for interactions between electrically charged particles, like attraction between opposite charges and repulsion between like charges. This force governs everything from electricity and magnetism to light and chemical bonds.
4. Gravitational Force
* Range: Infinite
* Description: The weakest of the four forces, but its range is infinite. It's responsible for attracting objects with mass towards each other. The force of gravity keeps us on Earth and governs the movement of planets, stars, and galaxies.
Important Note: While the electromagnetic and gravitational forces technically have infinite range, their strength decreases rapidly with distance. This means their effect becomes negligible over large distances.
