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.

This book is intended for use in Physics laboratories as a workbook for carrying out practical physics experiments by secondary school students and first year higher institution students. The objective is to have an all-in-one workbook from which various relevant physics experiments can be performed in a manner that also prepares students for practical physics examinations especially those of the West African Senior School Certificate Examination (WASSCE) and the National Examination Council (NECO).

Machines enable us do work more easily; they have gradually become part of our existence. This book presents ideas on the workings of basic machines in very understandable manner. There are lots of numerical examples and exercises that have been used to help facilitate the students' quantitative understanding of the subject. So, read and enjoy

Forces and fields are a great deal in Physics. In this book, we present the ideas of forces and fields in a simple-to-understand and interactive manner. Our intention is that students grasp the concept of forces in Physics and that they understand why fields are used to express forces in nature. Only gravitational forces/fields are extensively treated in this book, other forces/fields are treated extensively in other books in this series. For a more beautiful understanding, we have used a good number of relevant numerical examples/exercises to present the ideas.
