            知識點:牛頓定律-2019年物理復習資料-福建函授專科


                一、主要內容

              本章內容包括力的概念及其計算方法,重力、彈力、摩擦力的概念及其計算,牛頓運動定律,物體的平衡,失重和超重等概念和規律。其中重點內容重力、彈力和摩擦力在牛頓第二定律中的應用,這其中要求學生要能夠建立起正確的“運動和力的關系”。因此,深刻理解牛頓第一定律,則是本章中運用牛頓第二定律解決具體的物理問題的基礎。

              二、基本方法

              本章中所涉及到的基本方法有:力的分解與合成的平行四邊形法則,這是所有矢量進行加、減法運算過程的通用法則;運用牛頓第二定律解決具體實際問題時,常需要將某一個物體從眾多其他物體中隔離出來進行受力分析的“隔離法”,隔離法是分析物體受力情況的基礎,而對物體的受力情況進行分析又是應用牛頓第二定律的基礎。因此,這種從復雜的對象中隔離出某一孤立的物體進行研究的方法,在本章中便顯得十分重要。

              三、錯解分析

              在本章知識應用的過程中,初學者常犯的錯誤主要表現在:對物體受力情況不能進行正確的分析,其原因通常出現在對彈力和摩擦力的分析與計算方面,特別是對摩擦力(尤其是對靜摩擦力)的分析;對運動和力的關系不能準確地把握,如在運用牛頓第二定律和運動學公式解決問題時,常表現出用矢量公式計算時出現正、負號的錯誤,其本質原因就是對運動和力的關系沒能正確掌握,誤以為物體受到什么方向的合外力,則物體就向那個方向運動。




              例:甲、乙兩人手拉手玩拔河游戲,結果甲勝乙敗,那么甲乙兩人誰受拉力大?

              「錯解」因為甲勝乙,所以甲對乙的拉力比乙對甲的拉力大。就像拔河一樣,甲方勝一定是甲方對乙方的拉力大。

              「錯解原因」產生上述錯解原因是學生憑主觀想像,而不是按物理規律分析問題。按照物理規律我們知道物體的運動狀態不是由哪一個力決定的而是由合外力決定的。甲勝乙是因為甲受合外力對甲作用的結果。甲、乙兩人之間的拉力根據牛頓第三定律是相互作用力,甲、乙二人拉力一樣大。

              「分析解答」甲、乙兩人相互之間的拉力是相互作用力,根據牛頓第三定律,大小相等,方向相反,作用在甲、乙兩人身上。

              「評析」生活中有一些感覺不總是正確的,不能把生活中的經驗,感覺當成規律來用,要運用物理規律來解決問題。
