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.
