aFriction is the force that opposes motion but inertia is the reluctance of anobject to change its state of rest or motion. [B1]Friction is dependent on weight but inertia is dependent on mass. [B1|bWeight depends on gravitational field strength, thus it is not constanteverywhere.Weight is...

英语翻译The simple fact shows that the more of the force of friction is got rid of,the farther will the ball travel,and we are led to infer that,if all the impeding forces of gravitation and resistance could be removed,there is no reason why the ball,once in motion,should ever stop. ...
正在翻译,请等待...[translate] aThe force needed to set a body in motion against friction is more than that needed to maintain it in motion at constant speed. 力量在行动比维护那需要需要设置一个身体反对摩擦是更多它在行动以匀速。[translate]...
Friction Friction is a force that opposes motion between two surfaces that are touching. All surfaces have “hills and valleys” which stick to the “hills and valleys” of another surface when they touch. Friction Factors Rougher surfaces create more friction. (more hills and valleys) Greater ...
the dominant microscopic mechanism for the contact friction is the nonlinear, thermally activated stick-slip dynamics of the contacting asperities, which increases the friction force logarithmically with the sliding velocity6,7. Recent studies have shown that there exists even the minute, noncontact energ...
As there is still much to learn about friction, who knows what the future holds for this essential force? What is certain, however, is that physicists are excited at its huge potential.1 How do you understand that friction is a force that is "hard to resist"?2 What important events in...
