Abstract
Physics studies the nature and phenomena which commonly can be observed in everyday life. Traffic is one of those situations, and it is believed that a rapprochement between the physical concepts and situations applied in everyday traffic can enable the student best understandings of Physics in middle school and above all, that this knowledge can be used during the life of the individual. However, verify that the graduates of the school establish relationships between Physical content with phenomena observed in traffic is still a major field of study. This article presents the work of validation of a questionnaire prepared for a master's research. To this end, the validity of content was accomplished by judges' specialists; We calculate the internal consistency through the Cronbach's alpha coefficient, obtaining 0.74 value, as well as using the Mann-Whitney U Test to see if there were differences between the averages of the two groups. The results attest that the instrument has validity for the purposes of research, consisting of a test to check the conceptual physics Affairs retention in high school graduates.
