There are four forces of nature. Two are familiar to everyone; two are less so.
First, gravity is the force that pulls us to the surface of the Earth, keeps the planets in orbit around the Sun and causes the formation of planets, stars and galaxies. There are four conventionally accepted fundamental interactions—gravitational, electromagnetic, strong nuclear, and weak nuclear. Each one is understood as the dynamics of a field. The gravitational force is modelled as a continuous classical field.
There are four fundamental interactions that we know of. These four interactions account for all observed forces. These interactions are: Strong Nuclear, Electromagnetic, Weak Nuclear and Gravitational. The strongest of these four is the Strong Nuclear.
Gravity is the weakest force as its coupling constant is small in value. Gravity cannot be felt by us in daily life because of the huge universe surrounding us. Electromagnetic force is undoubtedly stronger as it deals with microscopic particles (electrons, protons). Gravity is always attractive in nature.
