電光阻力天平利用游標原理，能比較準確地讀出指針的位置。上皿天平秤盤在上側靈敏度較低。電子天平它是傳感技術、模擬電子技術、數字電子技術和微處理器技術發展的綜合產物，具有自動校準、自動顯示、去皮重、自動數據輸出、自動故障尋跡、超載保護等多種功能。電子天平通常使用電磁力傳感器（見稱重傳感器），組成一個閉環自動調節，準確度高，性好。當秤盤上加上被稱物時，傳感器的位置檢測器發生變化，并通過放大器反饋使傳感器線圈中的電流增大，該電流在恒定磁場中產生一個反饋力與所加載荷相平衡；同時，該電流在測量電阻Rm上的電壓值通過濾波器、模/數轉換器送入微處理器，進行數據處理，后由顯示器自動顯示出被稱量數值。實現了天上人間的統一，這是在自然哲學上的偉大貢獻。眾所周知，在理解光的本質上持微粒說。但他在同胡、惠更斯等討論光的本質時，說光具有這種或那種本能激發以太的振動。這意味著以太是光振動的媒的著作《自然哲

由此看來，奧耶領的發明權了上的確認。在很長時期里，天平制造業中流行一種理論，認為天平的橫梁越長天平越靈敏。但是有一個叫波爾·邦格的人卻不受這種理論的，1866年，他設計、制造了一架短橫梁分析天平。后來，在天平設計理論方面，他也有建樹。下圖所示的就是1866年邦格制造的早的一臺短梁天平。羅馬時代晚期的錢幣天平羅馬時代晚期的錢幣天平天平的改進，除了橫梁、點、游碼、刻度等方面以外，還在其它方面，例如，19世紀前半期，已經出現了旋鈕天平。旋鈕天平有什么優點呢？原來，早期的天平，橫梁架在的柱上，用時和不用時都是一樣的。后來分析天平出現了，分析天平的刀口用瑪瑙制成，為了刀口的損傷，不用天平時。。力的量綱為MLT-2。中文名力外文名force提出者艾薩克·提出時間1686年應用學科力學適用領域范圍力學符號F單位（N）三要素作用點，大小，方向矢量性矢量作用效果使物體發生形變或運動狀態改變測量工具彈簧秤或彈簧測力

力學也可按所研究物體的性質分為質點力學、剛體力學和連續介質力學。連續介質通常分為固體和流體，固體包括彈性體和塑性體，而流體則包括和氣體。16世紀到17世紀間，力學開始發展為一門的、的學科。伽利略通過對拋 就確定了冷卻定律，即當物體表面與周圍有溫差時，單位時間內從單位面積上散失的熱量與這一溫差成正比。[4]天文成就1672年創制了反射望遠鏡。他用質點間的萬有引力證明，密度呈球對稱的球體對外的引力都可以用同的
