Observation and experiment have afforded us the means of translating , as it
were , from Kinematics into Dynamics , and vice versa . This is merely mentioned
now in order to show the necessity for , and the value of , the preliminary matter

It is well to observe here , that since , by our formula , we have generally S v =
and since nothing has been said as to the magnitudes of s and t , we may take
these as small as we choose . Thus we get the same result whether we derive
from ...

Their relative motions with regard to the deck are what we immediately observe ,
but if we compound with these the velocity of the steamer itself we get evidently
their actual motion relatively to the earth . Again , in order to get the relative ...

The axioms of the present chapter must therefore be considered to be due to
actual experience , in the shape either of observation or experiment . How such
experience is to be conducted will form the subject of a subsequent chapter . 172.

It must , of course , be specified in what latitude the observation is made . Thus ,
let W be the mass of a body in pounds ; g the velocity it would acquire in falling
for a second under the influence of its weight , or the earth's attraction diminished
