kinetic friction force

基本解释

The frictional force remains constant, dependent on the friction, the kinetic friction coefficient, is always the same...
摩擦力不守恒，它取決於摩擦力，動能摩擦系數，一直是相同的。
It is pointed out that translational kinetic energy and rotational kinetic energy mutually transferred by sliding friction force, but it only has positive acting.
討論滑動摩擦力作功，說明了滑動摩擦力可以使剛躰的平動動能和轉動動能之間相互轉換，但縂是作負功。
Popularization and application of ion nitrided titanium parts have shown that they are suitable for long-term use in harsh environment under kinetic load, friction force and corrosive media.
耐磨性能和在還原性介質中的耐蝕性能，可使鈦材在高度動負荷、摩擦力和強腐蝕介質三者同時存在的苛刻環境中長期使用。
