Abstract

In this study, we investigated the sliding friction of Teflon (polytetrafluoroethylene: PTFE) samples on an inclined glass plate with a smooth transparent surface. The sliding velocity and contact area of the samples were evaluated as functions of the sliding length and inclined angle, and their relationships were determined to examine the effect of the contact area on the sliding velocity. Our results showed that the velocity decreased as the contact area increased, due to the wear of the samples, suggesting that the contact area plays an important role in sliding friction.
