Analyzing Data Flashcards
Scientific Notation can be used to express any number as a number between 1 to 10 (known as the ?) multiplied by 10 raised to a power
coefficient
In 1960, an international committee of scientists met to update the existing metric system. The revised international unit system is called ?
Système International d’Unités,
Sci notation:
ax10(b)
A= digit term
B=exponential term
based on an object or event in the physical world.
base unit
To better describe the range of possible measurements, scientists add ? to the base units. This task is made easier because the metric system is a decimal system – a system based on ?
Prefixes, units of 10
defined in terms of the seven
base quantities via a system
of quantity equations.
Derived Units:
the space occupied by an object.
Volume is
Volume formula
1ml=1cm^3
a physical property of matter is defined as the amount of mass per unit volume.
Density is
Si derive unit for density is
Kg/m^3
1 g/cm^3
Denisity equation
Mass/vol
a systematic approach to problem solving that uses conversion factors to move, or convert, from one unit to another.
Dimensional Analysis
ratio of equivalent values having different units.
A conversion factor is a
Error
is defined as the difference between an experimental value and an accepted value.
Percent error
expresses error as a percentage of the accepted value.
