This first chapter deals with one of the most basic principles of motion, which happens to be known as Newton’s first law. Not coincidentally, it has something to do with Isaac Newton. It’s a nice law to start out with because it doesn’t require any math and, after all, it is the first law. This chapter is also your first step toward understanding what science knowledge you need to plan a trip to the moon. Also included in the free offering from NSTA Press is the book’s Table of Contents and Preface.
