Abstract Title: Students’ understanding on rigid body rotation
Abstract: Previous studies have shown that students have difficulties in understanding concepts related to the circular motion of particles and to rotational motion and torque [1]. However, there are few studies on rigid body rotational dynamic.

The objective of our study is to inquire into students' understanding of torque and angular momentum when they tackle problems of a rigid object rotating about a fixed axis. We have designed an open-ended questionnaire. In designing the questions, we developed an epistemological analysis to rise the key concepts that high school students have to know in order to understand the rotation of rigid body in a proper way. We used a phenomenographic analysis [2], which is focused on the explanations rather than in the correctness of the answers. We will present questions and results.
