In order to be consistent with the physical equation, a new parameter is introduced. This parameter char-acterizes the existence of fractional components in the system. A relation between the fractional order time derivative and the new parameter is found. Different particular cases are analyzed %K C¨¢lculo Fraccionario %K sistema masa-re sorte-amortiguador %K derivada de Caputo %K componentes fraccionarias %U http://www.actauniversitaria.ugto.mx/index.php/acta/article/view/328
