Book excerpt: Newton's laws of motion are fundamental to understanding how the forces that act on objects compel them to move. While the laws appear simple and obvious, they present very elegant description on the interaction between force and matter. The laws have witnessed ground-breaking applications in the dynamics of objects like Earth satellites and planets. Our thinking is that it is very important for science students to understand fundamental truths about these laws, and so we have developed this book with this in mind. The book presents very clear explanations of things we think students ought to know about the Newton laws. There are also numerical examples to guide the students' understanding quantitatively, and exercises to test their understanding of the topic.
