Chapter-1 SI Units and Statics PHYSICS The word Physics comes from the Greek word phusis meaning nature , introduced by the ancient scientist Aristotle . Man has always been fascinated by nature. So, he questioned and sought answers for every phenomena nature could offer. The branch of science which is devoted to the study of nature and natural phenomena is called Physics. It is expected that all the events in nature takes place according to some basic laws. Physics reveals these basic laws from day-to-day observations. The knowledge of physics accumulated till 1900 is called classical physics that deals with macroscopic phenomena. It includes subjects like Mechanics Thermodynamics Electromagnetism, and Optics The recent knowledge beyond 1900 is termed modern physics , consisting of 2 basic theories. 1. Relativity 2. Quantum mechanics
PHYSICS IN RELATION TO SCIENCE, SOCIETY AND TECHNOLOGY Among the various disciplines of science, the only discipline which can be regarded as being most fundamental is physics. It has played a key role in the development of all other disciplines. For example,
Physics in Relation to Chemistry The study of structure of atoms, radioactivity, X-ray, diffraction, etc., in physics has enabled chemists to rearrange elements in the periodic table and to have a better understanding of chemical bonding and complex chemical structures.

Physics in Relation to Biological Science The optical microscopes developed in physics are extensively used in the study of biological samples. Electron microscope, X-rays and radio isotopes are used widely in medical sciences.
Physics in Relation to Astronomy The giant astronomical telescopes and radio telescopes have enabled the
