The main goal of this book is to present principles of classical mechanics using case studies involving human movement. The book assumes a background in calculus and physics. Vector algebra and vector differentiation are introduced in the text and are used to describe the motion of objects. Advanced topics such as three-dimensional motion mechanics are treated in some depth. Whenever possible, the analysis is also presented graphically, by using diagrams and software-created sequences of human movement in an athletic event or a dance performance. Each chapter contains illustrative examples and problem sets.
