The Fundamental Forces of Nature
The gravitational force, the electromagnetic force and the nuclear force correspond to the fundamental forces of nature.
Amidst the myriad of physical phenomena, there are four fundamental interactions involved. These interactions are forces, namely: gravitational force, electromagnetic force, strong nuclear force and weak nuclear force.
Gravitational Force
The mutual attraction between bodies because of their masses is called gravitational force.
The gravitational force can be noticed in the mutual attraction between Earth and Sun
Electromagnetic Force
The attraction or repulsion between bodies due to their electrical charges and/or their magnetization is called electromagnetic force.
The movement of the needle of an electromagnetic compass
occurs due to the electromagnetic force
Weak Nuclear
Force The force developed between leptons and hadrons is called the weak nuclear force.
of electrons in some radioactive substances
Strong Nuclear Force
The force that maintains nuclear cohesion and the union between quarks is called the strong nuclear force.
Protons have positive charges causing mutual repulsion between them, the force that holds them
together in the atomic nucleus is called the strong nuclear force.
Unifying the Fundamental Forces
Scientists are trying to unify the fundamental forces; but the attempts have not yet been successful. It is up to us to wait for what the scientific world has in store for us and whether the unification of the four fundamental forces will be possible.
