The Four Fundamental Forces

• The Four Fundamental Forces:

  • Gravitational Force
  • Electromagnetic Force
  • Strong Nuclear Force
  • Weak Nuclear Force
• GRAVITATIONAL FORCE is the force of attraction between each and every particle in the universe.
• Gravitational force is always attractive and pulls matter together.
• Gravitational force is the WEAKEST of the forces.
• GRAVIITATIONAL FORCE is very long ranged (is furthest reach of all forces, therefore of great importance in cosmology).
• GRAVITATIONAL FORCE is the most important force for understanding the large scale structure and evolution of the universe.
• ELECTROMAGNETIC FORCE determines how electrically charged particles interact with each other and with magnetic fields.
• ELECTROMAGNETIC FORCE can be attractive or repulsive.
• ELECTROMAGNETIC FORCE holds electrons in their orbital shells around the nucleus of an atom.
• WEAK NUCLEAR FORCE or a.k.a, weak interaction.
• WEAK NUCLEAR FORCE is very powerful.
• ELECTROMAGNETIC FORCE is long ranged, but weaker than the strong force.
• WEAK NUCLEAR FORCE is very short ranged and acts on scale of atomic nuclei.
• WEAK NUCLEAR FORCE cause radioactive decay in the form of beta decay.
• BETA DECAY is a neutron spontaneously breaks up into a proton, an electron, and an antineutrino.
• WEAK NUCLEAR FORCE is responsible for synthesizing different chemical elements in stars and in supernova explosions.
• STRONG NUCLEAR FORCE or a.k.a, strong interaction.
• STRONG NUCLEAR FORCE is strongest of the forces.
• STRONG NUCLEAR FORCE keeps protons and neutrons bound together in the nuclei of atoms (prevents protons from flying apart because of the repulsion between their like-charges).
• Because strong nuclear force binds nuclear particles so tightly together, huge amounts of energy are released when nuclei are fused together (fusion) or broken apart (fission).
• STRONG NUCLEAR FORCE is the underlying source of the vast quantities of energy that are generated by the nuclear reactions that power the stars.
