This work presents an investigation where some alternative conceptions are the origin and the processing of varied interpretations. As for that, it was proposed to high school students the resolution of certain problems that involved rigid bodies in constant rotation. These problems should be analysed within the perspective of the speed concept, which was previously known by the students, but abandoned by the explanations generated by the alternative conceptions.
