This text is divided into five major areas: mechanics, matter and heat, wave motion and sound, electricity and magnetism, and light and modern physics.
Problem-Soling Method. Figure P 1 shows examples illustrating how problem-solving method is used in the text. See page 53 for the detailed presentation of the problem-solving method.
Chapter Objectives. Figure P.2 shows the objectives for Chapter 7, "Rotational Motion:"
Examples. Worked examples are consistently displayed in the problem-solving for at and used to illustrate and clarify basic concepts and problems. Since many students learn by example, a large number of examples are provided. The example in Figure P.3 shows how conversion factors are displayed and used.
Problem Sets. Problem sets follow each section that is problem related. The problem-solving icon,(shown at right) is located in the margin of problem sets as a reminder to students of the use and importance of the problem-solving method. This method is easily remembered and provides a valuable skill that can be used and applied daily in other technical and science courses and on the job.
Chapter End Matter. A chapter glossary, a summary of chapter formulas, chapter review questions to review concept understanding, and chapter review problems help students to review for quizzes and examinations.
This text is written at a language level and at a mathematics level that is cognizant c and beneficial to most students in technical programs that do not require a high level of mathematics rigor. The authors have assumed that the student has successfully completed one year of high school algebra or its equivalent. Simple equations aft formulas are reviewed, and any mathematics beyond this level is developed in t~ text. The manner in which the mathematics is used in the text displays the net for mathematics in technology. For the better prepared student, the mathematical sections may be omitted with no loss in continuity.
Sections are short, and each deals with only one concept. The need for t investigation of a physical principle is developed before undertaking its study, a many diagrams are used to aid students in visualizing the concept. A large number of examples and problems allow students to develop and check their mastery of a concept before moving to another.
This text is designed to be used in a vocational-technical program in a community college, a technical institute, or a high school for students who plan pursue a technical career. The topics were chosen with the assistance of technicians and management from several industries, as well as faculty technical consultants. Suggestions from users and reviewers of the previous edition were used extensively in this edition. The chapter on measurement introduces students to basic units and so mathematical skills. For those students who lack a metric background or who nee review, a significant development of the metric system is found in Chapter 1, w ' measurements are presented as approximate numbers and then used consistently throughout the text. Chapter 2 introduces students to the problem-solving me 7 that is used in the rest of the text. Vectors are developed in Chapter 3, followed motion, a comprehensive study of force, work and energy, rotational energy, ; simple machines.
The treatment of matter includes a discussion of the three states of matter, density, fluids, pressure, and Pascal's principle. The treatment of heat includes temperature, specific heat, thermal expansion, change of phase, and gas laws.
The chapter on wave motion and sound deals with basic wave characteristics, the nature and speed of sound, the Doppler effect, and resonance.
The section on electricity and magnetism begins with a brief discussion of static electricity, followed by an extensive treatment of do circuits and sources, Ohm's law, and series and parallel circuits. The chapter on magnetism, generators and motors is largely descriptive, but it allows for a more in-depth study if desired. Then ac circuits and transformers are treated extensively.
The chapter on light briefly discusses the wave and particle nature of light, but deals primarily with illumination. The chapter on reflection and refraction develops the images formed by mirrors and lenses. The chapter on modern physics provides an introduction to the structure and properties of the atomic nucleus, radioactive decay, nuclear reactions, and radioactivity.
A companion laboratory manual is available. An Instructor's Resource Manual that includes Complete Solutions, Transparency Masters, and a Test Item . is available at no charge to instructors using this text.
Physics is useful. Architects, mechanics, builders, carpenters, electricians, plumbers, and engineers are only some of the people who use physics every day in their jobs or professions. In fact, every living person uses physics principles every hour of the day. The movement of an arm can be described using principles of the lever. All building trades, as well as the entire electronics industry, also use physics.
Physics is often defined as the study of matter, energy, and their transformations. The physicist uses scientific methods to observe, measure, and predict physical events and behaviors. However, gathered data left in someone's notebook in a laboratory are of little use to society.
The basics of physics is really universal communication in the language of mathematics. The physicist describes physical phenomena in an orderly form in mathematical terms understood worldwide. Mechanics is the base on which almost all other areas of physics are built. Motion, forces, work, electricity, and light are topics confronted daily in industry and technology. The basic laws of conservation of energy are needed to understand heat, sound, wave motion, electricity, and electromagnetic radiation.
Physics is always changing as new frontiers are established in the study of the nature of matter and physics today. The topics studied in this course, however, will probably not be greatly changed with new research and will remain a classical foundation for vocational work in many, many fields. We then begin our study with the rules of the game—measurement, followed by a systematic problem-solving method. The end result will hopefully be a firm base on which to build a career study in almost any technical or vocational field.

My review of Physics for Career Education are not the best. I found to be MANY errors (typographic errors ) in the book. Much of it in the back of the book where the answers are.Was this review helpful? Yes NoThank you for your feedback. Report this reviewThank you, this review has been flagged.
