Research findings are presented concerning the internal structure analysis of a multiple choice test constructed to detect whether or not the student has the Newtonian conception of the interrelationship between force and motion. These findings show that the test has two different but related factors: one subset of items checks students' ability to identify forces in certain physical situations according to the Newtonian view while another subset checks whether or not they relate the resultant force with acceleration. In addition, the analysis also shows that the two subsets have slightly different predicting power concerning student performance in mechanics. This kind of analysis might be very relevant for teacher's work regarding learning evaluation.
