Why do we study physics? Which device will you choose to measure the length of a small cylinder? How will you determine the thickness of a piece of wire? How will you find the volume of small stone? why ice floats while a coin sinks in the water? After learning this unit you will be answer these and other similar questions. “No one undertakes research in physics with ia INTRODUCTION TO PHYSICS the intention of winning One of the most basic and ancient science is the a prize. It is the joy of Physics. The word science refers to the study of a fact by discovering something collecting information through observation, presenting no one knew before.” it in a mathematical way, justifying the idea with Stephen Hawking experiment and finally making a conclusion about the fact. Thus physics can be defined as: Physics is the branch of science which observes the nature represents it mathematically and conclude It basically deals with the behavior and structure of matter and the energy that derives the matter. Physics is the branch of natural science that studies Physics Derived from matter, its motion, its behavior through space and time Ancient Greek and _ the related entities of energy and force. Physics is ‘physicos’ meaning one of the most fundamental scientific disciplines, and ‘knowledge of nature’. its main goal is to understand how the universe behaves. It is a matter of fact that Physics can be considered as the mother of all sciences. The beauty of physics lies in its Laws that govern this whole universe from an atom to large scale galaxies and in its experiments from home to large scale experiment labs. Physicist are categorized into two categories: those who observe the nature solve its mysteries with available
