摘要：

An experiment investigating the direction of the frictional force exerted by a horizontal surface on a rolling object is discussed. Students generally find the results surprising; however, the observations support the predictions of rotational dynamics. The experiment is suitable for an introductory mechanics laboratory. © 1979, American Association of Physics Teachers. All rights reserved.
