Verma (Author) About the Author Harish Chandra Verma is a Nuclear Experimental Physicist and author. H C Verma wrote other books like Industrial Families in India, Foundation Science: Physics For Class 9, Dominion Status vs Complete Independence etc. H C Verma got his Doctoral degree from the Indian Institute of Technology Kanpur. He went on to work as a lecturer and reader at the Patna University. As a physicist, his chief areas of interest are in Materials Applications, Condensed Matter and also on Earth Science related issues like extinction boundaries and meteorites. At present he is working on a book on Electromechanics.

A force is a push and pull in a particular direction. Force is a vector quantity and its SI unit is newton (N). For force, the following  two questions are very important:    (a) Which agent exerted this force ?    (b) On which object this force was exerted ? For, example, if a person is standing in a storm, then he feels that a force is acting on him. Wind exerts force on the person and person experiences this force.  - With every force, point of application is associated.  - Each force that is exerted on an object is caused by a particular body in its environment. Like in above example, wind is exerting force on the person. Force are classified in four categories:  (a) Gravitational force  (b) Electromagnetic force  (c) Nuclear force  (d) Weak force We will discus about these forces, in detail in the corresponding units of the Focal Points. In mechanics, we will mainly deal with contact forces, friction forces, spring force, tension in string etc, which all are e

P hysics is the natural science that involves the study of matter and its motion through space and time, along with related concepts such as energy and force. One of the most fundamental scientific disciplines, the main goal of physics is to understand how the universe behaves.
