Have you ever wondered why objects drop to the ground or what keeps the Moon from crashing into the Earth? Isaac Newton wondered why. Do you know whether a bowling ball will fall faster than a cricket ball? Galileo could have told you! In this fascinating book, author Paul Fleisher answers these questions and many more as he explores the scientific laws that describe how and why objects move. Fun experiments that readers can do on their own and helpful illustrations introduce the basic principle of classical mechanics.
 
This edition of Objects in Motion: Principles of Classical Mechanics Paul Fleisher’s Secrets of the Universe has been fully revised by the author and features all of the original illustrations by Patricia Keeler.
