This document discusses the different types of fundamental forces: strong nuclear, weak nuclear, electromagnetic, and gravitational. The strong nuclear force binds quarks together to form protons and neutrons. The weak nuclear force is responsible for nuclear beta decay. The electromagnetic force attracts or repels charged particles via electric and magnetic forces. Gravity is the attractive force between any two masses and keeps planets, stars, and galaxies in motion. Videos and references are provided for additional information on each force.
