Introduction to Physics

The word Physics comes from the Greek word fusis mini nature. Its Sanskrit equivalent is Bhautika i.e. the physical world. In Physics we attempt to explain diverse physical phenomena in terms of a few concepts and laws. The effort is to see the physical world as manifestation of some universal laws in different domains and conditions.

In Physics we study different forms of matter, their properties and the transformations that they undergo. It is a major signs dealing with fundamental constitutes of universe, the forces they exert on one another and the results produced by these forces. Physics a basic discipline in the category of natural sciences which also includes other disciplines like chemistry and biology.

Sometimes in modern Physics in more sophisticated approach is taken that incorporates elements of three states; it relates to the laws of symmetry and conservation, such as those pertaining to energy, momentum, charge and parity.
