Regulae motus cartesi
Reg. 1. Si duo corpora aequalia aequali velocitate in
partes contrarias teudentia concurrant, ambo reflectentur
qua venere caleritate et directione
Reg. 2 si duo corpora, sibi aequali velocitate occurrant
qua ante
inaequalia
ambo eadem velocitate ferentur et directione majoris
Rey. 3. Si duo corpora aequalia inaequali velocitate
sibi occurrant, ambo pergent ererea directione
et velocitate ceterioris et velvertate ambo eadem eq
velocitate ambo aequali velocitate ferentur, et
directione celerioris salica Et  tarduus accipiet
mediam dimidium differentiae celeritatum
Rey. 4 se corpus incurrat in quiscens paule majy,
ipsum non movebit sed repelletur qua venit celeritate
qua corpus quiescens magis resitit mognae celeritati quum
parvae
Rey. 5. si corpus in incurrat in quisiens
sims
paulo minus. ita ibunt, directione incurrentis, et
velocilate tali, ut quantitas motus sit idem quiante
Ut siu corpus incumcu, sit duplum, motus erit tertia parte
celeritatis
Reg. 6 si corpus in currat in quiescens aequale
partim aupellet, partim reflecteretur it si habeat 4
cqadus velocitatis dabit ipsi  excipienti unuse
gadum, et cum tribus resicnis reflectetur (oun
e
intolligo hauc regulam)
Reg. 7. si corpus assa quatur aliud, et celerius
esset minus sed excessus celeritatis majod quam
mognitudinis ita hoan sferetur caleritas ut ambo
simil in easdem partes movenatur; sinu
excessus celeritatis minor quam migitudinis
in currens in contrarias partes toto suo mota
reflecteretu
