How did the ancient Egyptians build the pyramids? How do we build giant skyscrapers today? To understand these marvels, you need to understand simple machines such as levers and inclined planes. Machines and Motion contains 35 lessons that will teach your child about simple machines and the laws of motion, which are the basic principles governing the physical world around us. 35 lessons. Full-color.

The updated third edition of the classic book that provides an introduction to electric machines and their emerging applications The thoroughly revised and updated third edition of Electromechanical Motion Devices contains an introduction to modern electromechanical devices and offers an understanding of the uses of electric machines in emerging applications such as in hybrid and electric vehicles. The authors—noted experts on the topic—put the focus on modern electric drive applications. The book includes basic theory, illustrative examples, and contains helpful practice problems designed to enhance comprehension. The text offers information on Tesla's rotating magnetic field, which is the foundation of reference frame theory and explores in detail the reference frame theory. The authors also review permanent-magnet ac, synchronous, and induction machines. In each chapter, the material is arranged so that if steady-state operation is the main concern, the reference frame derivation can be de-emphasized and focus placed on the steady state equations that are similar in form for all machines. This important new edition: • Features an expanded section on Power Electronics • Covers Tesla's rotating magnetic field • Contains information on the emerging applications of electric machines, and especially, modern electric drive applications • Includes online animations and a solutions manual for instructors Written for electrical engineering students and engineers working in the utility or automotive industry, Electromechanical Motion Devices offers an invaluable book for students and professionals interested in modern machine theory and applications.

This text provides a basic treatment of modern electric machine analysis that gives readers the necessary background for comprehending the traditional applications and operating characteristics of electric machines—as well as their emerging applications in modern power systems and electric drives, such as those used in hybrid and electric vehicles. Through the appropriate use of reference frame theory, Electromagnetic Motion Devices, Second Edition introduces readers to field-oriented control of induction machines, constant-torque, and constant-power control of dc, permanent-magnet ac machines, and brushless dc machines. It also discusses steady-state and transient performance in addition to their applications. Electromagnetic Motion Devices, Second Edition presents: The derivations of all machine models, starting with a common first-principle approach (based upon Ohm's, Faraday's, Ampere's, and Newton's/Euler's laws) A generalized two-phase approach to reference frame theory that can be applied to the ac machines featured in the book The influences of the current and voltage constraints in the torque-versus-speed profile of electric machines operated with an electric drive Complete with slides, videos, animations, problems & solutions Thoroughly classroom tested and complete with a supplementary solutions manual and video library, Electromagnetic Motion Devices, Second Edition is an invaluable book for anyone interested in modern machine theory and applications. If you would like access to the solutions manual and video library, please send an email to: [email protected].

The God's Design Physical World Teacher Guide reveals the wonders of God's creation through the study of physics and the mechanisms of heat, machines, and technology. Each lesson contains at least one hands-on activity to reinforce the concepts being taught and a "challenge" section with extra information and activities designed especially for older students.In addition to the lessons, special features in each book include biographical information on interesting people as well as fun facts to make the subject more engagingTeaches children an understanding that God is our Creator, and the Bible can be trusted.Designed to build critical thinking skills and flexible enough to work with all learning styles, the lessons require minimal teacher preparation, are multi-level for 3rd-5th and 6th-8th grades, as well as being fun and easy-to-use. The course includes a helpful daily schedule, as well as worksheets, quizzes, and tests. The information contains tips on how to teach science, properly contrasting creation vs. evolution, and integrating a biblical worldview.

The great physicist's elegant, concise survey of Newtonian dynamics proceeds gradually from simple particles of matter to physical systems beyond complete analysis. Includes "On the Equation of Motion of a Connected System," from Volume II of Electricity and Magnetism. Appendixes deal with relativity motion and principles of least action.

Motion is a change in an object's position. This fascinating title explains in a clear, simple way how objects are moved by a change in energy. Simple activities show young readers how energy is changed by applying a force, either by coming in contact with an object or by a force that does not touch it physically, like gravity. Teacher's guide available.
