Understanding physics concepts is the main goal of learning process in school. However, it was frequently found that students faced difficulties to understand the concepts on physics taught in class. These difficulties mainly due to the difference between students ' initial knowledge and the concepts taught by the teacher. For example, students assumed that a top can spin for a long time due to big speed of rotation, so it can maintain the spinning balance. However according to physics concept, the longer spinning balance is caused by the moment inertia is big. When the angular momentum of the top is conserved, the moment inertia can maintain the spinning of the top. This assumption frequently called as preconceptions. The incompatibility of preconceptions with the physics concepts above may lead misconceptions. This study aims to identify conception of students one science class in Senior High School of Jogoroto, Jombang on Dynamic Rotation and Rigid Body Equilibrium and their causes using four-tier diagnostic test. A total of 30 students participated in this study. The instrumen contains 16 numbers of physics-concepts questions. The highest conception is dominated by misconceptions that occur in rotational motion, equilibrium and center of gravity concepts was due to humanistic thinking and praconception. © 2020 IOP Publishing Ltd.
