An alternative approach for exploring friction in laboratory

Abstract

We propose an active learning path for developing laboratory skills in the pre-service education of physics teachers. An exponential relationship can arise under certain conditions in a simple mechanical system when friction is present. How to design a series of experiments to verify if the proposed relationship correctly describes the system? Can materials from everyday life be used? What data analysis can teachers suggest to students? How to effectively present the measures in a graph? How to promote in-depth discussions with students on the most significant experimental aspects? These are the main issues that can be examined in designing.
