| Abstract Title: | Probing Students' Conceptions About Rolling in Different Contexts |
|---|---|
| Abstract: | Research has shown that students have several misconceptions about rotational motion and rolling (Rimoldini & Singh, 2005). Students do not understand the relationship between the speeds of various points on a rolling wheel. They also do not understand the relationship between the translational and rotational speeds of a wheel that rolls without slipping. We conducted a study to further extend the research by Rimoldini and Singh (2005). Specifically, we explored students' difficulties with regard to rolling without slipping in three different contexts: a single rolling bicycle wheel, two differently sized wheels in a penny-farthing bicycle, and a horizontal plank pushed forward on a rolling drum. In each case, students in two different introductory physics classes responded in writing to open-ended questions asking them to compare the speeds at various points of the wheels in the three contexts. We will describe students' conceptions about rolling in these different contexts. |
