‘fmall which it would not yield to. Thefe? 
and fuch like experiments, look as if matter 
had no attachment to reft, no wis refiftentia, 
but that it readily yielded to motion. hata 
body is put in motion by the very fmalleft 
force, and yet that it refifts a change from 
reft to motion, are propofitions which may 
appear not to be very confiftent: yet both 
true in fact. And the difficulty will va- 
nifh, by attending to the power of the v/s 
inertia or xefiftentia, that it is not meafured 
merely by the fize or bulk of the body to 
which it belongs, but has a relation to the 
momentum of the impingeing body. The leaft 
force will put the greateft body in motion: 
but from this it does not follow, that matter 
does not refift a change from reft to motion. 
It only follows, that this refiftance is always 
lefs than the vs motrix. To calculate the 
proportion betwixt the vis motrix and the re- 
fiftence of a body at reft, fhall be the fubje& 
of the next chapter.
