This book provides an illustration of classical mechanics in the form of problems (at the bachelor level) inspired for most of them by contemporary research in physics, and resulting from the teaching and research experience of the authors. A noticeable feature of this book is that it emphasizes the experimental aspects of a large majority of problems. All problems are accompanied by detailed solutions: the calculations are clarified and their physical significance commented in depth. Within the solutions, the fundamental concepts from undergraduate lectures in classical mechanics necessary to solve the problem are recalled when needed. The authors systematically mention recent bibliographical references (most of them freely accessible via the Internet) allowing the reader to deepen his understanding of the subject, and thus contributing to the building of a general culture in physics.
