FUNDAMENTAL FORCES OF NATURE
There are four fundamental forces of nature that have been identified the universe, namely, Weak Force, Strong Force, Electromagnetic Force and Gravitational Force. They are found to have rather different properties and play central roles in making the universe what it is today.
Weak force is a force between elementary particles that causes certain processes that take place with low probability, as radioactive beta-decay and collisions between neutrinos and other particles. Neutrinos interactions are created as a result of certain types of radioactive decay or nuclear reactions such as those that take place in the Sun, in nuclear reactors, or when cosmic rays hit atoms. Radioactive decay is spontaneous disintegration of a radionuclide accompanied by the emission of ionizing radiation in the form of alpha or beta particles or gamma rays.
Strong interaction is a fundamental interaction between elementary particles that causes protons and neutrons to bind together in the atomic nucleus. Also called strong force. The strong force is a short-range attractive force between baryons that holds together the nucleus of the atom.
Electromagnetic force is the fundamental force that is associated with electric and magnetic fields and is responsible for atomic structure, chemical reactions, the attractive and repulsive forces associated with electrical charge and magnetism, and all other electromagnetic phenomena. It is carried by the photon. Magnetic forces are created by and act on only moving charges while electric forces are created by and act on, both moving and stationary charges.
Gravitational force is the force of attraction between all masses in the universe; especially the attraction of the earth's mass for bodies...
