力學(xué)也可按所研究物體的性質(zhì)分為質(zhì)點力學(xué)、剛體力學(xué)和連續(xù)介質(zhì)力學(xué)。連續(xù)介質(zhì)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(xué)開始發(fā)展為一門的、的學(xué)科。伽利略通過對拋

則會產(chǎn)生較大的誤差。后應(yīng)看刻度尺的刻度值。刻度代表的長度值不僅反映了刻度尺不同的準確程度，而且還涉及到測量結(jié)果的有效性。量程和刻度值應(yīng)從實際測量要求出發(fā)兼顧選擇。大秦DPHL-2F7,DPHL-2F0,DPHL-2FF,DPHL-2FZ

看刻度尺的零刻度是否磨損，如已磨損則應(yīng)重正確使用刻度尺正確使用刻度尺選一個刻度值作為測量的起點。其次看刻度尺的測量范圍（即量程）。原則上測長度要求一次測量，如果測量范圍小于實際長度，勢必要刻度尺測量若干次，
