Experiment Overview

Friction plays an important role in many technical devices and surfaces.  It is, thus important for students of physics and engineering to be aware of the different types of friction forces, such as static friction, kinetic friction, rolling friction and fluid resistance.  This experiment deals with kinetic friction between two surfaces and how it can be measured in the laboratory.  It provides by means of a rather simple experiment a link between the theoretical aspects of friction which are developed in lectures and a hands-on experiment to show how friction can be measured in a laboratory situation.  The experiment also provides students with an introduction to statistical techniques used to describe the results of experiments.
