Types of Force: Gravitational, Electric, Frictional, Viscous drag and Upthrust

Force may be described as a pull or a push that causes a body to accelerate or change the velocity of the body                                                       Or Force is defined as rate of change of momentum. It is a vector quantity. S.I. unit – Newton. All the force in universe are basis on for fundamental interactions. 1. […]


The first quantitative measurements of electric force between point charge bodies was made by Charles Augustin de Coloumb in 1785 by means of a very sensitive balance (torsion balance). It states that the magnitude of force between two point charges is directly proportional to the product of two charges and inversely proportional to the square […]
