Physics Textbook Part - 1 for Class - 11 - 11086

This book is the result of the renewed efforts of the present
Textbook Development Team with the hope that the students will appreciate the
beauty and logic of physics. The students may or may not continue to study physics
beyond the higher secondary stage, but we feel that they will find the thought
process of physics useful in any other branch they may like to pursue, be it finance,
administration, social sciences, environment, engineering, technology, biology or
medicine. For those who pursue physics beyond this stage, the matter developed
in these books will certainly provide a sound base.

Physics is basic to the understanding of almost all the branches of science and
technology. It is interesting to note that the ideas and concepts of physics are
increasingly being used in other branches such as economics and commerce, and
behavioural sciences too. We are conscious of the fact that some of the underlying
simple basic physics principles are often conceptually quite intricate. In this book,
we have tried to bring in a conceptual coherence. The pedagogy and the use of
easily understandable language are at the core of our effort without sacrificing the
rigourof the subject. The nature of the subject of physics is such that a certain
minimum use of mathematics is a must. We have tried to develop the mathematical
formulations in a logical fashion, as far as possible.
