...(1) Friction is proportional to the force applied perpendicular to the contact surface and is independent of the apparent contact area between the objects, (2) kinetic friction is independent of the sliding speed, (3) static friction is generally greater than kinetic friction. Of these, (1) and (2) were announced by Guillaume Amontons (1663-1705) of France in 1669 and later confirmed by C. Coulomb, and are therefore known as Amonton's law or Coulomb's law. (1) was also used in the explanation of mechanics above, but these are empirical laws obtained for friction on surfaces that are not lubricated, and do not always hold strictly. ... *Some of the terminology that mentions "Amontons, G." is listed below.

…(1)摩擦力は接触面に垂直に加えられる力に比例し,物体間の見かけの接触面積とは無関係である,(2)動摩擦力はすべり速度には無関係である,(3)一般に静摩擦力は動摩擦力より大きい。このうち(1)と(2)は,1669年にフランスのアモントンGuillaume Amontons(1663‐1705)が発表し,その後C.クーロンが確認したことから,アモントンの法則またはクーロンの法則と呼ばれている。前述した力学の説明にも(1)を用いたが,これらはもともと潤滑を行っていない面の摩擦について得られた経験則で,つねに厳密に成立するというものではない。… ※「Amontons,G.」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
