無(wú)數(shù)學(xué)生立即把離心運(yùn)動(dòng)緊緊的和力連到了一起 認(rèn)為離心運(yùn)動(dòng)是在離心力的作用之下進(jìn)行的運(yùn)動(dòng)所以在解釋脫水筒的脫水原理的時(shí)候 冒出了類(lèi)似“這是離心力作用的結(jié)果”的答案雖然書(shū)上已經(jīng)提示了離心運(yùn)動(dòng)是物體自身慣性的表現(xiàn) 是物體保持自身運(yùn)動(dòng)狀態(tài)不變的體現(xiàn)可是以上的“鏈接”太根深蒂固了！直接導(dǎo)致了同學(xué)門(mén)概念的不清晰不如直接跳回“運(yùn)動(dòng)”進(jìn)行分析 兩類(lèi)“傾向”的不同便會(huì)清晰眼前了以前所說(shuō)的“傾向”是外界要將物體的這種運(yùn)動(dòng)狀態(tài)改變?yōu)榱硪环N運(yùn)動(dòng)狀態(tài)的“傾向”；而離心運(yùn)動(dòng)中的“傾向”則是抵抗外界將其將其本身運(yùn)動(dòng)狀態(tài)改變 從而使自身運(yùn)動(dòng)狀態(tài)不變的“傾向”！一個(gè)是“傾向”于運(yùn)動(dòng)狀態(tài)的變化一個(gè)是“傾向”于保持原來(lái)運(yùn)動(dòng)狀態(tài)、抵制運(yùn)動(dòng)狀態(tài)的改變 根據(jù)牛頓第二定律對(duì)力的定義 后者當(dāng)然沒(méi)有力的作用因此離心運(yùn)動(dòng)不是在離心力作用下的運(yùn)動(dòng)2． 一種異端的說(shuō)法有些平時(shí)喜歡沒(méi)事就亂想的同學(xué)說(shuō)：“既然物體的運(yùn)動(dòng)形式都是由圓周運(yùn)動(dòng)改變?yōu)榱藙蛩僦本€(xiàn)運(yùn)動(dòng)了何以說(shuō)他的運(yùn)動(dòng)狀態(tài)沒(méi)有發(fā)生變化？既然運(yùn)動(dòng)狀態(tài)都發(fā)生了變化又何以說(shuō)他沒(méi)受到力？”于是思維活躍的他們提出了離心運(yùn)動(dòng)和
