Abstract | The common undergraduate experiment for determining the static coefficient of friction between a wooden block and a horizontal tabletop often produces inconsistent results. We show how several factors influence the measured magnitude and consistency of the coefficient of friction. We utilize a fractional factorial experimental design, which is a method that has been specifically developed to effectively and efficiently uncover key factors that most strongly influence experimental results. © 2004 American Association of Physics Teachers. |
