This paper describes the theses that constitute the Theory of Dynamic Interactions. It is the scientific legacy of its promoter, Dr. Barceló who, after more than forty years developing this research project, has published his first book in the English language: New Paradigm in Physics. This book, as well as the bibliography and videos on this dynamic theory, is described in this article, which analyzes the behavior of rigid bodies subjected to accelerations by rotational movements, contributing new hypotheses of dynamic behavior.
