Levers All Around

This informative book introduces young readers to levers, describing how they work, how they help people do jobs, and how they are used for fun. The book also includes a "That’s Amazing!" special feature, several "Did You Know?" facts, a table of contents, quiz questions, a glossary, additional resources, and an index.

INTERNATIONAL BESTSELLER • An engaging, deeply researched guide to flourishing in a world of increasing stress and negativity—the inspiration for one of the most popular TED Talks of all time “Powerful [and] charming . . . A book for just about anyone . . . The philosophies in this book are easily the best wire frames to build a happy and successful life.”—Medium Happiness is not the belief that we don’t need to change; it is the realization that we can. Our most commonly held formula for success is broken. Conventional wisdom holds that once we succeed, we’ll be happy; that once we get that great job, win that next promotion, lose those five pounds, happiness will follow. But the science reveals this formula to be backward: Happiness fuels success, not the other way around. Research shows that happy employees are more productive, more creative, and better problem solvers than their unhappy peers. And positive people are significantly healthier and less stressed and enjoy deeper social interaction than the less positive people around them. Drawing on original research—including one of the largest studies of happiness ever conducted—and work in boardrooms and classrooms across forty-two countries, Shawn Achor shows us how to rewire our brains for positivity and optimism to reap the happiness advantage in our lives, our careers, and even our health. His strategies include: • The Tetris Effect: how to retrain our brains to spot patterns of possibility so we can see and seize opportunities all around us • Social Investment: how to earn the dividends of a strong social support network • The Ripple Effect: how to spread positive change within our teams, companies, and families By turns fascinating, hopeful, and timely, The Happiness Advantage reveals how small shifts in our mind-set and habits can produce big gains at work, at home, and elsewhere.

You might not realize it, but you use many kinds of levers every day. The fork you use to eat, the broom you use to sweep, and the scissors you use to cut paper are all levers. Even the bones inside your body are levers. Levers help us lift things and get work done—readers learn all about the science behind levers in this fun and fact-filled book. Bright photographs and illustrations accompany accessible text to help readers understand the science concepts presented in this book. Readers will also find a detailed graphic organizer and glossary inside, allowing them to independently explore these simple machines.

We can find levers all around us. Baseball bats, crowbars, seesaws, and wheelbarrows are all examples of levers. The three classes of levers make difficult lifting jobs easier with the help of leverage. Each class of lever is set up differently, but has all the same parts. Levers are made up of a plank that pivots at a fulcrum. Readers will learn about the difference between each class of lever, where levers can be found, and how levers make many jobs we do much easier.

"Body Physics was designed to meet the objectives of a one-term high school or freshman level course in physical science, typically designed to provide non-science majors and undeclared students with exposure to the most basic principles in physics while fulfilling a science-with-lab core requirement. The content level is aimed at students taking their first college science course, whether or not they are planning to major in science. However, with minor supplementation by other resources, such as OpenStax College Physics, this textbook could easily be used as the primary resource in 200-level introductory courses. Chapters that may be more appropriate for physics courses than for general science courses are noted with an asterisk symbol (*). Of course this textbook could be used to supplement other primary resources in any physics course covering mechanics and thermodynamics"--Textbook Web page.
