牛頓力學者,蓋宏觀低速物體之理。經典力學有二假定也,一曰時空恆定,二曰量皆可測入極微。
基本定律
牛頓定律之一曰凡萬物皆亦持直動亦靜止,至外力使之變。
牛頓定律之二曰萬物之加速度正比於所受之合力而反比於質量,加速方向亦與力同向。
牛頓定律之三曰萬物所受作用力皆有反作用力,且二者大小相等,方向相反。
萬有引力定律曰萬物凡有質量者,皆以力相吸。其為力,兩者質量之積大而益大,然兩者距離之平方大而益小也。

If a component is awkward to type directly, choose its total stroke count and then its first stroke. This is an input aid, not a judgement about how difficult the component is to learn. The five first-stroke classes follow the IRG system.
