This study presents the results of a study on the development of the concept of force and their possible applications in physics teaching. The historical study has focused on Aristotelian natural philosophy, medieval theories of strength in impressed and on classical Newtonian mechanics. The Newtonian concept of force was also an object lesson of physics analyzed in this study. In this lesson, conducted in a preuniversity course, spontaneous conceptions or alternative conceptions of students about the concept of force proved very entrenched, resulting in studies on the Model Change on Conceptual and epistemological obstacles in view Bachelardian. The theoretical frameworks adopted led us to trace parallels between spontaneous conceptions revealed by the students and some views about the concept of force found in the study of history. The results show that while some old conceptions have been replaced by scientifically Newtonian concept of force, they are still present in the students' ideas and resist to changes even after the study of Newton's laws. Like main result shows that the history of science can be a great ally for the deconstruction of alternative conceptions, particularly when these concepts were previously presented and overcome the course of history of the development of a concept
