On one hand, at Nova Scientia (1537), the author explained that the trajectories were composed by two straight lines and a circular arc; on the other, at Quesiti et Inventioni Diverse (1546), the same trajectories were presented only as curves. These two different approaches to the trajectory of projectiles suggested to some historians that Tartaglia had changed his mind, leaving, in a way, his old beliefs. Thus, based on original documents, this paper seeks to resume Tartaglia arguments in order to understand the reasons which would have led him to change his approaches in those two works. Despite other factors, we present evidence that Tartaglia had, around 1540, come in contact with works that had almost none circulation before. With this in mind, our work provides evidence that there is some continuity between the arguments of Tartaglia on the trajectories in these two works / Este trabalho tem por objetivo tratar alguns aspectos das diferentes argumentações de Niccolò Tartaglia (1500-1556) sobre as trajetórias dos projéteis. Na Nova Scientia (1537), as trajetórias seriam compostas por duas retas e um arco de circunferência. Já nos Quesiti et Inventioni Diverse (1546), elas são apresentadas completamente curvas. Esses dois enfoques diferentes dados ao tema sugeriram a alguns historiadores que Tartaglia teria mudado de ideia, abandonando, de certa maneira, suas antigas convicções. Desse modo, baseado em documentos originais, este trabalho busca retomar os argumentos de Tartaglia de modo a compreendermos as razões que o teriam levado a dar dois diferentes enfoques nas duas obras. Dentre outros fatores, apresentamos indícios de que Tartaglia passou a contar, por volta de 1540, com obras anteriormente desconhecidas e que pouco circulavam até então. Tendo isso em vista, nosso trabalho fornece indícios de que podemos observar certa continuidade entre as argumentações de Tartaglia sobre as trajetórias nessas duas obras
