This book is written primarily for the first year of pre-medical students. There are thirteen chapters which contain mechanics, vibrations, waves, basics of thermodynamics, electromagnetics, current electricity, optics, atomics and nuclear physics.The drafting of this book obeys the following rules: the knowledge system of basic physics should be introduced entirely and briefly to medical applications. The knowledge should be considered, the derivation of physics rules should be deemphasized. The understanding of basic concepts, rules and simple application of physics should be stressed; the calculus is avoided so that the students can focus on the knowledge and rules of physics, instead of being distracted by mathematical difficulties.
