Analise dinamica da tendencia para o equilibrio num modelo simples: a   Segunda Lei de Newton e a Segunda Lei da Termodinamica
  We relate Newton's Second Law with the Second Law of Thermodynamics through the analysis of a simple model introducing a dynamic pressure concept. From this analyses we can clarify some conceptual problems resulting from several concepts of heat and work on the First Law of Thermodynamics.
