牛顿运动定律是经典力学的基础定律。

通常的现代表述

  • 第一定律：假若施加于某物体的外力为零，则该物体的运动速度不变（也称惯性定律）。
  • 第二定律：施加于物体的外力等于此物体的质量与加速度的乘积（也称加速度定律）。
  • 第三定律：当两个物体相互作用于对方时，彼此施加于对方的力，其大小相等、方向相反（也称作用力与反作用力定律）。

文言版

拉丁语原文

  • Lex. I. Corpus omne perseverare in statu suo quiescendi vel movendi uniformiter in directum, nisi quatenus a viribus impressis cogitur statum illum mutare.
  • Lex. II. Mutationem motus proportionalem esse vi motrici impressæ, & fieri secundum lineam rectam qua vis illa imprimitur.
  • Lex. III. Actioni contrariam semper & æqualem esse reactionem: sive corporum duorum actiones in se mutuo semper esse æquales & in partes contrarias dirigi.

英文译文

  • LAW I. Every body perseveres in its state of rest, or of uniform motion in a right line, unless it is compelled to change that state by forces impressed thereon.
  • LAW II. The alteration of motion is ever proportional to the motive force impressed; and is made in the direction of the right line in which that force is impressed.
  • LAW III. To every action there is always opposed an equal reaction: or the mutual actions of two bodies upon each other are always equal, and directed to contrary parts.
