Explains the physics of gravity and gravitational pull, offering information on the contributions made in this area by Copernicus, Galileo, and Newton.
I love how practical & understanding these books are. Experiments/examples are easy to do at home, helping you understand it better. This was my second reading & I made many more connections.
I have the newer edition published by Living Book Press, and I highly recommend it. This book is a perfect introduction to classical mechanics for middle school students. I'd venture that it would help many freshmen make better sense of their physical science textbooks, too. Clear, concise explanations, accessible illustrations and examples that students will readily grasp, a touch of formulas, and plenty of applicable historical references combine to great effect. Bonus are the timeline, mini biographies, and further resource lists in the back as well as the intro explaining natural law. Note: this book is part of a series and all share these "bonus" features, albeit with particular content related to the book's subtopics.
