Physics is a conceptual science that demands a profound understanding of its fundamental principles. However, in practice, many students struggle to master physics concepts effectively. Understanding the concepts of moment of force and moment of inertia is still a challenge in learning physics at the secondary school level. Many students experience misconceptions due to incorrect interpretations of these concepts. This study aims to describe the misconceptions and causes of students′ misconceptions on the material of the moment of force and moment of inertia using the Certainty of Response Index (CRI) method. The research method employed was a descriptive, quantitative approach involving 40 students, utilizing the CRI test instrument and a questionnaire to investigate the causes of misconceptions. The results show that misconceptions occur predominantly in indicators related to the moment of inertia about the axis of rotation. The leading causes of misconceptions came from the textbook′s low quality and the lack of proper conceptual explanations. These findings emphasize the importance of developing more representative learning media as well as improvements in the preparation of physics teaching materials. © Published under licence by IOP Publishing Ltd.
