Every day, all over the world, people travel: short trips or great, long voyages, moving slowly and steadily or racing along at super-fast speeds. They make their trips in cars, trains, planes, ships and on bikes-and some people have even blasted off in rockets! But how did these vehicles become what we know now? With intricately illustrated timelines, this book takes readers on a journey through the developmental history of various modes of transportation - from chariots to electric cars, dugout canoes to ocean liners, cable cars to bullet trains, and the many iterations in between. The fascinating stories behind each of these machines join together to reveal a comprehensive history of how new and inventive forms of transportation have built off one another to change our world.

Give your students a kick start on learning with our Force and Motion 3-book BUNDLE. Students begin by exploring different Forces. Conduct several experiments on the force of friction and air resistance. Understand that acceleration and deceleration are examples of unbalanced forces. Next, take the mystery out of Motion. Graph the velocity of students walking home from school at different speeds. Follow directions to find your way using a treasure map. Finally, get familiar with Simple Machines. Conduct an experiment with first-class levers to study distance and force. Find the resistance force when walking up an inclined plane. Each concept is paired with hands-on activities and experiments. Aligned to the Next Generation State Standards and written to Bloom's Taxonomy and STEAM initiatives, additional crossword, word search, comprehension quiz and answer key are also included.

Drones, RC cars, artificial limbs, Roombas-the robots have arrived! Anyone interested in taking control before the machines do needs a helpful resource. Author and physics teacher Bobby Mercer will show readers 20 inexpensive, easy-to-build and robots that can be built with everyday items. The Robot Book will teach readers how to use recycled motors and computer components, junk drawer supplies, and old mechanical toys to build a variety of devices. They will learn how to turn a toothbrush, an old cell phone, and scrap wire into a Brush Bot, or hack a toy car to hotwire a Not-So-Remote Bot. A small electric fan, several craft sticks, and rubber bands make a Fan-Tastic Dancing Machine, and drinking straws, string, tape, and glue can be used to construct a working model of the human hand. Every hands-on project contains a materials list and detailed step-by-step instructions with photos. Mercer also includes explanations of the science and technology behind each robot, including concepts such as friction, weight and mass, center of gravity, kinetic and potential energy, electric circuitry, DC vs. AC current, and more. Teachers will appreciate the opportunity to augment their STEM curricula while having fun at the same time. These projects are also perfect for science fairs or design competitions. Bobby Mercer has been a high school physics teacher for over two decades. He is the author of The Flying Machine Book, The Racecar Book and Junk Drawer Physics and lives with his family outside of Asheville, North Carolina.

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.

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.
