Laws of Motions (Leges Motus)

Here's an extract from Newton's Principia Mathematica (Written in Latin). Newton's Laws exactly as they had been written:

Law 1: Corpus omne perseverare in statu suo quiescendi vel movendi uniformiter in directum, nisi quatenus a viribus impressis cogitur statum illum mutare.

Translates to English as:
Every body perseveres in its state of rest or uniform motion in a straight line, except insofar as that state is compelled to change by forces impressed.

Law 2: Mutationem motus proportionalem esse vi motrici impressæ, & fieri secundum lineam rectam qua vis illa imprimitur.

Translated in English as:
The alteration of motion is proportional to the motive force impressed, and is made in a straight line in which that force is impressed.

Law 3: Actioni contrariam semper & æqualem esse reactionem: sive corporum duorum actiones in se mutuo semper esse æquales & in partes contrarias dirigi.

Translated in English as:
Every action there is always opposed an equal reaction: or actions of two bodies upon each other are always equal, and directed to contrary parts.
