All volumes of this free physics textbook are written to entertain pupils, students, teachers and everybody who is curious about the world of motion. These five volumes present established physics. (A bonus volume, on a research topic, is also available.) Here are the tables of contents.

The bonus volume

More details on the status and research for the bonus volume, on the strand model, are found here. This sixth volume covers research on an approach to unify fundamental physics, an approach that arose directly from writing the first five textbook volumes. The approach differs from other candidates: all its predictions agree with experiments and all observations about nature, also the ones unexplained after the first five textbook volumes, are explained. The approach is still a topic of research, and thus the sixth bonus volume is not part of the five textbook volumes.
