This clear introduction to the basic concepts of physics covers the key topics required by students in technical mechanics, electricity and magnetism, light and optics, thermodynamics, and modern physics. The book assumes very little math background on the students' part--the necessary math is developed concurrently with the physical concepts. Emphasizes problem-solving and is notable for developing a systematic approach to the solving of problems. The level of detail of explanations is considerably greater than is usual for tech physics books. This book is class-tested and has numerous pedogogical chapter objectives, worked examples, important equations and terms, review questions, and problem sets. Employs three systems of SI, CGS absolute, and the English gravitational, the SI being stressed in later chapters.
