40
in a conversion fraction the numerator always ___ the denominator
so the fraction always equals ___
=
| 1
41
to convert one metric unit to another you must
multipy the given value by the conversion factor
42
to convert you place units to be converted in what part of the fraction
denominator = units to be converted
43
steps of dimensional analysis
id given units / units to be converted
create a conversion factor
denominator of conversion factor is the same unit that is to be converted
cross multiply so that units to be converted ends up as the numerator
44

| alcohol or mercury
45
meniscus
curve of liquid in graduated cylinder - point at which liquid is measured
mm
46
general properties of matter
mass
weight
volume
density
47
mass can also be described as
inertia
48
inertia
resistance of an object to changes in its motion
Galileo
49
weight
exists because of objects mass, responce of the objects gravitational pull
