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

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).

Motion is a core aspect of Physics; ideas from it are used in almost all other aspects of Physics. In this book, we present the subject in very clear and fascinating manner. Our aim is to make students and readers grasp the core concepts without the usual boredom associated with most scientific textbooks. Motion parameters like distance/displaement, speed/velocity, and acceleration were nicely explained. The book contains an excellent treatment of displacement-time and velocity-time graphs. Equations of motion were extensively presented and wrapped-up with motions under gravity. You will want to see other subjects in sciences treated this way when you finish reading it.
