INTRODUCTION TO PHYSICS
introduction to physics Physics falls under a broader category of Science. Science is divided into three areas namely Biology, Physics and Chemistry. The main objective of these subjects is to study and try to understand the universe and everything in it. What is physics? Physics is the branch of science which deals with matter and its relation to energy. It involves study of physical and natural phenomena around us. Examples of these phenomena are formation of rainbow, occurrence eclipse, the fall of things from up to down, the cause of sunset and sunrise, formation of shadow and many more. Physics as a subject is divided into six broad branches as discussed below. i) Mechanics This branch deals majorly with motions under the influence of forces. Under this branch, we look into details the aspects of linear, circular and oscillatory motions as well as motion of fluids ii) Geometrical Optics This branch takes a keen look at the behavior of light in various media. iii) Electricity and
