Abstract

The purpose of this research is to (1) identify students' mental models in explaining the concepts on rotational dynamics and equilibrium of rigid body.(2) knowing the consistency of the use of students' mental models in explaining the material for rotational dynamics and rigid body equilibrium. This is a descriptive quantitative research. This study involved 199 students senior high school from SMAN 1 Mlati, SMAN 2 Sleman, SMAN 1 Ngaglik who had studied the rotational dynamics and equilibrium of rigid body. The sample was selected using stratified random sampling technique. In this research using a test instrument rotational dynamics and rigid body equilibrium are multiple choice. The results of the students' answers are then analyzed using model analysis. Furthermore, interviews were conducted to dig deeper into the mental models of the students. Based on the model plot, some students already have a correct understanding of the concepts of moment of force, moment of inertia, rigid body equilibrium and have a mixed model on the concepts of rotational kinetic energy and angular momentum. Each concept has eigenvalues that vary from 0.61 until 0.84, the magnitude of the eigenvalues (>0.65) shows that students are consistent in using mental models
