①平動(dòng)的物體一般可以看作質(zhì)點(diǎn)做平動(dòng)的物體，由于物體上各點(diǎn)的運(yùn)動(dòng)情況相同，可以用一個(gè)點(diǎn)代表整個(gè)物體的運(yùn)動(dòng)，在這種情況下，物體的大小、形狀就無(wú)關(guān)緊要了，可以把整個(gè)物體當(dāng)質(zhì)點(diǎn)。例如：平直公路上行駛的汽車，車身上各部分的運(yùn)動(dòng)情況相同，當(dāng)我們把汽車作為一個(gè)整體來(lái)研究它的運(yùn)動(dòng)的時(shí)候，就可以把汽車當(dāng)作質(zhì)點(diǎn)。當(dāng)然，假如我們需要研究汽車輪胎的運(yùn)動(dòng)，由于輪胎上各部分運(yùn)動(dòng)情況不相同，那就不能把它看作質(zhì)點(diǎn)了。要注意的是：同一物體在不同情況下有時(shí)可看質(zhì)點(diǎn)，有時(shí)不可以看作質(zhì)點(diǎn)，一列火車從北京開(kāi)到上海，研究火車的運(yùn)行的時(shí)間，可將火車看成質(zhì)點(diǎn)，而火車過(guò)橋時(shí)，計(jì)算火車過(guò)橋的時(shí)間，不可以將火車看成質(zhì)點(diǎn)。②有轉(zhuǎn)動(dòng)但轉(zhuǎn)動(dòng)為次要因素例如：研究地球公轉(zhuǎn)時(shí)，可把地球看作質(zhì)點(diǎn)；研究地球自轉(zhuǎn)時(shí)，不能把地球看作質(zhì)點(diǎn)。③物體的形狀、大小可忽略再如：乒乓球旋轉(zhuǎn)對(duì)球的運(yùn)動(dòng)的較大的影響，運(yùn)動(dòng)員在發(fā)球、擊球時(shí)都要考慮，就不能把乒乓球簡(jiǎn)單看作質(zhì)點(diǎn)。

3.適用條件（1）萬(wàn)有引力定律只適用于質(zhì)點(diǎn)間引力大小的計(jì)算。當(dāng)兩物體間的距離遠(yuǎn)遠(yuǎn)大于每個(gè)物體的尺寸時(shí)，物體可以看成質(zhì)點(diǎn)，直接使用萬(wàn)有引力定律計(jì)算。（模型）研究相互接觸的兩個(gè)人之間的萬(wàn)有引力時(shí)，不能把他們看作質(zhì)點(diǎn)。（2）當(dāng)兩物體是質(zhì)量均勻分布的球體時(shí)，它們間的引力也可直接用公式計(jì)算，但式中的r是指兩球心間距離。研究太陽(yáng)和地球之間的萬(wàn)有引力，可以把它們看作質(zhì)量均勻的球體。當(dāng)研究物體不能看成質(zhì)點(diǎn)時(shí)，可以把物體假想分割成無(wú)數(shù)個(gè)質(zhì)點(diǎn)，求出兩個(gè)物體上每個(gè)質(zhì)點(diǎn)與另一物體上所有質(zhì)點(diǎn)的萬(wàn)有引力，然后求合力，這是微積分的思想。萬(wàn)有引力定律產(chǎn)生于對(duì)太陽(yáng)系行星運(yùn)動(dòng)的研究，但它對(duì)物質(zhì)運(yùn)動(dòng)的適用性卻要廣泛得多?？梢赃@樣說(shuō)，宇宙中凡有引力參與的一切復(fù)雜的現(xiàn)象，無(wú)不要?dú)w結(jié)到這樣一條十分簡(jiǎn)潔的定律之中，這不能不使人驚嘆宇宙萬(wàn)物超乎尋常的和諧及人類理性思考所具有的統(tǒng)攝力。
