Particule matérielleLe terme « particule matérielle » (material particle en anglais) désigne une petite portion d'un corps, de matière solide ou fluide, constituée d'un nombre suffisamment grand de particules élémentaires. La matière est pleine de vide. Un corps de matière solide ou fluide est un domaine discontinu de particules composites (protons, neutrons), elles-mêmes composées de particules élémentaires. Les dimensions des particules élémentaires sont très petites devant les distances qui les séparent.
