This document discusses standards, measurement, and significant figures in physics. It defines measurement as determining scale, dimensions, or capacity with a standard unit. Principal standards are units that have been predefined, while derivative standards are obtained from principal standards. Examples of tools used to measure length, mass, time, current, temperature, light intensity, and amount of substance are provided. Rules of significant figures are also mentioned. The purpose is to help students learn about these key physics concepts and how to apply them in studies and daily life.
4. Identify physical standards in
everyday life and include them in
the principal standard and the
standard of generation.
know the measuring tools.
Understanding
the
rules
of
significant figures.
5. In physics you will always
be connected with the
measurement,
standard
and units. Do you know
what's
mean
the
measurement? On this
topic, you can learn a lot
about these concepts and
should be able to use it in
any study physics and in
daily.
6. Measurement is the determination of the scale,
dimensions, or capacity, with a standard or unit of
measurement
Principal Standard is the standard that the units have
been defined in advance.
Derivative Standard is standard units are obtained
from the principal standard
12. Lux meter
Tools to measure for
the light intensity
Tools to measure for
amount of subtance
Amount of substances are not
measured directly, but by
means of measuring the mass
of matter in advance.
13. Significant figure is the number
obtained from the measurements
consist of a significant number that is
certain (read the gauge) and the

or
questioned.
