摘要:
The introduction to rolling friction is studied in relation to the height that a ball attains rolling up an inclined track after rolling down a given height along another inclined track opposite from the first. The expressions obtained for a ball rolling down a rectangular inclined track and along a horizontal track are applied to the study of the distance run along two opposed inclined tracks. Different procedures are proposed to determine the coefficient of rolling friction of the ball with the track. The values calculated from the experimental data suggest their dependence with the ball radius.
