如何解釋磨擦力
Aug 23rd 2013, 14:32

請聰明的各位大大給我這個笨笨的好奇寶寶解答吧 (有些有點蠢 且字很多 拜託要耐心看完阿~)感激不盡 感激不盡 thank a zillion

問題有下列這些:

1.(最最基本)
請解釋物體與物體真正有接觸到嗎(越詳細越好)?

2.(基本)
假設:一張桌子上面放一本書 老師們解釋是支撐力(接觸力) 但我以微觀的看法 是這樣的:電子與電子之間有斥力 電子與質子有引力 而才兩力平衡的 這樣是否正確?

3.(正題)
磨擦力是原子與原子之間的庫倫靜電力嗎?

4.(正題)
假設以上皆為正確 為何與面積無關(如錯誤請給另答)?

5.(我的胡思亂想)
承4.假設以上皆為正確 磨擦力是否為↙(向左下角)的一個力呢(如我解釋不清楚 可以不用答-.-)?
