六、到此為止，我們了解到，作者對(duì)“笑”鯤鵬和別人的蜩與學(xué)鳩、斥鴳、宋榮子都一一作了否定。那么請(qǐng)大家討論一下，1、作者對(duì)鯤鵬和“知效一官，行比一鄉(xiāng)，德合一君，而征一國(guó)者”是不是肯定呢？明確：也都作了否定。否定后者好理解，關(guān)鍵是否定前者不好理解，因?yàn)椤蚌H鵬展翅”早已作為積極的意象被人們廣泛引用。但在本文中，作者在講述這一寓言故事時(shí)，突出的不是鯤鵬本身，而是風(fēng)力，“故九萬(wàn)里，風(fēng)斯在下矣，而后乃今培風(fēng)；背負(fù)青天，而莫之夭閼者，而后乃今將圖南”。對(duì)風(fēng)力作用的突出，實(shí)際上就是對(duì)鯤鵬的否定。作者寫(xiě)了“笑”的雙方，對(duì)“笑”的一方蜩與學(xué)鳩、斥鴳、宋榮子都作了否定，對(duì)被“笑”的一方鯤鵬和“知效一官，行比一鄉(xiāng)，德合一君，而征一國(guó)者”也都作了否定，并且對(duì)順便提及的野馬、塵埃、芥、大舟、朝菌、蟪蛄、冥靈、大椿、彭祖、列子等事物或者人物也都作了否定。這種全盤(pán)否定的態(tài)度，如果我們借用本文中的一個(gè)形象的詞語(yǔ)，可以說(shuō)是：笑！是的，本文也可以說(shuō)是：莊子“笑”萬(wàn)物！

猜想：既然物體下落過(guò)程中的運(yùn)動(dòng)情況與物體質(zhì)量無(wú)關(guān)，那么為什么在現(xiàn)實(shí)生活中，不同物體的落體運(yùn)動(dòng)，下落快慢不同呢？我們能否猜想是由于空氣阻力的作用造成的呢？如果沒(méi)有空氣阻力將會(huì)怎樣呢？學(xué)生討論后回答.三、猜想與假說(shuō)伽利略認(rèn)為，自由落體是一種最簡(jiǎn)單的變速運(yùn)動(dòng).他設(shè)想，最簡(jiǎn)單的變速運(yùn)動(dòng)的速度應(yīng)該是均勻變化的.但是，速度的變化怎樣才算均勻呢?他考慮了兩種可能：一種是速度的變化對(duì)時(shí)間來(lái)說(shuō)是均勻的，即經(jīng)過(guò)相等的時(shí)間，速度的變化相等；另一種是速度的變化對(duì)位移來(lái)說(shuō)是均勻的，即經(jīng)過(guò)相等的位移，速度的變化相等.伽利略假設(shè)第一種方式最簡(jiǎn)單，并把這種運(yùn)動(dòng)叫做勻變速運(yùn)動(dòng).四、實(shí)驗(yàn)驗(yàn)證實(shí)驗(yàn)驗(yàn)證是檢驗(yàn)理論正確與否的唯一標(biāo)準(zhǔn).任何結(jié)論和猜想都必須經(jīng)過(guò)實(shí)驗(yàn)驗(yàn)證，否則不成理論.猜想或假說(shuō)只有通過(guò)驗(yàn)證才會(huì)成為理論.所謂實(shí)驗(yàn)驗(yàn)證就是任何人，在理論條件下去操作都能到得實(shí)驗(yàn)結(jié)果，它具有任意性，但不是無(wú)條件的，實(shí)驗(yàn)是在一定條件下的驗(yàn)證，而與實(shí)際有區(qū)別.

三、制定實(shí)驗(yàn)方案的兩個(gè)問(wèn)題：1．怎樣測(cè)量（或比較）物體的加速度：引導(dǎo)學(xué)生思考、討論并交流。學(xué)生可能會(huì)提出下面的一些方案：方法一：測(cè)出初速度為零的勻加速直線運(yùn)動(dòng)的物體在 時(shí)間內(nèi)的位移 ，則 ；方法二：在運(yùn)動(dòng)的物體上安裝一條打點(diǎn)計(jì)時(shí)器的紙帶，根據(jù)紙帶上打出的點(diǎn)來(lái)測(cè)量加速度；方法三：測(cè)出兩個(gè)初速度為零的勻加速運(yùn)動(dòng)的物體在相同的時(shí)間內(nèi)發(fā)生的位移 、 ，則 ；方法四：測(cè)出兩個(gè)初速度為零的勻加速運(yùn)動(dòng)的物體在相同的位移內(nèi)所用的時(shí)間 、 ，則 ；2．怎樣提供并測(cè)量物體所受的恒力：教師提出：現(xiàn)實(shí)中，除了在真空中拋出或落下的物體（僅受重力）外，僅受一個(gè)力的物體幾乎是不存在的。然而，一個(gè)單獨(dú)的力作用效果與跟它大小、方向都相同的合力的作用效果是相同的，因此，實(shí)驗(yàn)中力 的含義指物體所受的合力。以在水平軌道上用繩牽引小車加速運(yùn)動(dòng)為例，小車受到四個(gè)力的作用，即重力、支持力、繩的拉力和軌道對(duì)小車的摩擦力（當(dāng)物體運(yùn)動(dòng)的速度比較小時(shí)，我們可以忽略空氣的阻力）。
