三、制定實驗方案的兩個問題：1．怎樣測量（或比較）物體的加速度：引導(dǎo)學(xué)生思考、討論并交流。學(xué)生可能會提出下面的一些方案：方法一：測出初速度為零的勻加速直線運動的物體在 時間內(nèi)的位移 ，則 ；方法二：在運動的物體上安裝一條打點計時器的紙帶，根據(jù)紙帶上打出的點來測量加速度；方法三：測出兩個初速度為零的勻加速運動的物體在相同的時間內(nèi)發(fā)生的位移 、 ，則 ；方法四：測出兩個初速度為零的勻加速運動的物體在相同的位移內(nèi)所用的時間 、 ，則 ；2．怎樣提供并測量物體所受的恒力：教師提出：現(xiàn)實中，除了在真空中拋出或落下的物體（僅受重力）外，僅受一個力的物體幾乎是不存在的。然而，一個單獨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，實驗中力 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動為例，小車受到四個力的作用，即重力、支持力、繩的拉力和軌道對小車的摩擦力（當物體運動的速度比較小時，我們可以忽略空氣的阻力）。

1．加速度與力的關(guān)系：實驗的基本思路是保持物體的質(zhì)量不變，測量物體在不同的力的作用下的加速度，分析加速度與力的關(guān)系。有了實驗的基本思路，接下去我們就要準備實驗器材，以及為記錄實驗數(shù)據(jù)而設(shè)計一個表格。為了更直觀地判斷加速度與力的數(shù)量關(guān)系，我們以 為縱坐標、 為橫坐標建立坐標系，根據(jù)各組數(shù)據(jù)在坐標系中描點。如果這些點在一條過原點的直線上，說明 與 成正比，如果不是這樣，則需進一步分析。2．加速度與質(zhì)量的關(guān)系：實驗的基本思路是保持物體所受力不變，測量不同質(zhì)量的物體在該力作用下的加速度，分析加速度與質(zhì)量的關(guān)系。有了實驗的基本思路，接下去我們就要準備實驗器材，以及為記錄實驗數(shù)據(jù)而設(shè)計一個表格。為了更直觀地判斷加速度與質(zhì)量的數(shù)量關(guān)系，我們以 為縱坐標、 為橫坐標建立坐標系，根據(jù)各組數(shù)據(jù)在坐標系中描點，根據(jù)擬合的曲線形狀，初步判斷 與 的關(guān)系是反比例函數(shù)。再把 圖像改畫為 圖像，如果是一條過原點的斜直線，說明自己的猜測是否正確。
