1、實驗名稱:TheMoon’sOrbit物理93E44891104王建中實驗目的:由所給的12個月面照片,量出不同的半徑R,進而推算出月球軌道背景知識說明:1.月球軌道近似於一橢圓形,所以會遵守克普勒定律,因此我們就可以由所良測到的月球視直徑,來推導月球軌道.2.當月球最靠近地球時(於近地點)會比離地球最遠(於遠地點)時來的大一些.這在古希臘時代的天文學家就已經知道了.3.月球與地球的距離R和它的是直徑d成反比關係;R=const./d.我們可將此常數設為2000.4.在測量月面視直徑的時候,多求幾個R,再取平均,會比較精準.在測量的過程中盡可能求其精準,因為這直接影
2、響到實驗結果.實驗方法:在月面上任取兩弦,並做其中垂線,以求得圓心,如此便可得d值.由公式R=4000/d球出R,在極座標上,依照已知之經度畫出12條線,將所得R值分別帶入可得12個點,如此便可描繪出一個近似的橢圓軌道.再將所得之12個R取平均值作圓,使之fit軌道上的12個點,則圓之圓心即為橢圓之中心.使用器材:photoshop,microsoftexcel量測數據列表:A1B1C1(A1+B1)/2(B1+C1)/2圓心R11250,31.5101.5,179.5101.5,397175.75,105.5101.5,288.25358,288.25280.52
