An easy-to-follow guide to introductory physics, from the Big Bang to relativity

All science, technology, engineering, and math majors in college and university require some familiarity with physics. Other career paths, like medicine, are also only open to students who understand this fundamental science. But dont worry if you find physics to be intimidating or confusing. You just need the right guide!

InPhysics I For Dummies, youll find a roadmap to physics success that walks you through every major topic in introductory physics, including motion, energy, waves, thermodynamics, electromagnetism, relativity, and more. Youll learn the basic principles and math formulas of physics through clear and straightforward examples and instruction, and without unnecessary jargon or complicated theory.

In this book, youll also find:

• Up-to-date examples and explanations appearing alongside the latest discoveries and research in physics, discussed at a level appropriate for beginning students
• All the info found in an intro physics course, arranged in an intuitive sequence that will give first-year students a head start in their high school or college physics class
• The latest teaching techniques to ensure that you remember and retain what you read and practice in the book

Physics I For Dummies is proof that physics can fun, accessible, challenging, and rewarding, all at the same time! Whether youre a high school or undergraduate student looking for a leg-up on basic physics concepts or youre just interested in how our universe works, this book will help you understand the thermodynamic, electromagnetic, relativistic, and everything in between.
