Axioms or Laws of Motion
From Motte's 1729 translation of Principia
LAW IEvery 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 IIThe 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 IIITo 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.
Axiomata sive Leges Motus
Lex ICorpus omne perseverare in statu suo quiscendi vel movendi uniformiter in directum, nisi quatenus a viribus impressis cogitur statum illum mutare.
Lex IIMutationem motus proportionalem esse vi motrici impressæ, & fieri secundum lineam rectam qua vis illa imprimitur.
Lex IIIActioni contrariam semper & æqualem esse reactionem: sive corporum duorum actiones in se mutuo semper esse æquales & in partes contrarias dirigi.
