人教版新課標(biāo)高中物理必修1伽利略對(duì)自由落體運(yùn)動(dòng)的研究教案2篇
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.
