 note = {We are apt to take the cause of rolling friction too simply : one takes it to rise from the slip, and the other to rise from the adhesion between rolling surfaces. Concerning rolling friction, however, the experimental data are too deficient now to decide which is the true. Rolling friction consists of many factors, the most important of which being the velocity term. It is one of the friction components and increases linearly with velocity. In this paper, this velocity term in the rolling friction of a ball on plane is treated experimentally, being seperated from t,he over-all rolling friction. The experiments are carried out by the pendulum type apparatus for dry, lubricated, and the other conditions., 資料番号: SA2353340000},
