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，它取决于摩擦力，动能摩擦系数，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.
讨论滑动摩擦力作功，说明了滑动摩擦力可以使刚体的平动动能和转动动能之间相互转换，但总是作负功。
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.
耐磨性能和在还原性介质中的耐蚀性能，可使钛材在高度动负荷、摩擦力和强腐蚀介质三者同时存在的苛刻环境中长期使用。
