PocketLab Voyager: A Study of Rolling Resistance

Submitted by Rich on Fri, 07/21/2017 - 17:19

In this experiment a coasting cart on a flat surface gradually slows down and stops due to rolling resistance.  Two very different surfaces are compared—a carpeted floor and a wood floor.  The purpose of this experiment is three-fold:  (1) to determine the force of rolling resistance, (2) to determine the coefficient of rolling resistance between the cart the surface on which it rolls, and (3) to gain a practical understanding of the meaning of this coefficient.  Voyager's range finder is used to collect data.
