Newton's Laws of Motion as found in Principia Mathematica

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 impressae et fieri secundum lineam rectam qua vis illa imprimitur.

Lex III: Actioni contrariam semper et aequalem esse reactionem: sive corporum duorum actiones is se mutuo semper esse aequales et in partes contrarias dirigi.


Translation:
Law 1: Every body continues in it's state of rest or of uniform motion in a right line, unless it is compelled to change that state by a force impressed on it.

Law 2: The rate of change of motion is proportiona to the motive force impressed; and it is made in the direction of the right line in which that force is impressed.

Law 3: The mutual actions of two bodies are always equal and dircted to contrary paths.


Cambridge adds that extra tinge of authenticity to studying physics :P
