書中闡述了其后兩百年間都被視作真理的三大運(yùn)動(dòng)定律。使用拉丁單詞“gritas”(沉重)來(lái)為現(xiàn)今的引力(grity)命名,并定義了萬(wàn)有引力定律。在這本書中,他還基于波義耳定律提出了分析測(cè)定空氣中音速的。[6]由
間的單位,我們就能給出速度和加速度的定義和度量。我們通過(guò)兩種途徑探討第二定律,即制和引力制。在制中,我們引進(jìn)物體的為單位,從而根據(jù)第二定律,把單位產(chǎn)生單位加速度的力作為單位力。

作的介紹。由于數(shù)學(xué)更深入地應(yīng)用于力學(xué)這個(gè)領(lǐng)域,使力學(xué)更加理論化。運(yùn)動(dòng)學(xué)用純粹的解析和幾何描述物體的運(yùn)動(dòng),對(duì)物體作這種運(yùn)動(dòng)的物理原因可不考慮。亦即從幾何方面來(lái)研究物體間的相對(duì)位置隨時(shí)間的變化。例如泰勒斯的學(xué)說(shuō):萬(wàn)物的根源是水。即使像德謨克利特、盧克萊修的原子論,總的來(lái)說(shuō)來(lái)評(píng)價(jià)還是很高的。但是他們的憑天才的臆測(cè)、思維與辯論,稱之為思辨哲學(xué)。到了中世,經(jīng)院哲學(xué)統(tǒng)治著??茖W(xué)、哲學(xué)淪為神學(xué)的奴婢。到16世
