2. MEANING OF
MEASUREMENT
Measurement is the process of observing and recording the observations that are
collected as part of a research effort.
To get the exact measurement of an object we make use of tools used in the field of
science, especially in physics called measuring instrument.
Examples of such instrument are chemical balance, spring balance, meter rule, caliper,
micrometer screw guage, clock, thermometer etc.

3. MEASUREMENT OF MASS
Mass is the quantity of matter contained in a body.
The instrument used in measuring mass is chemical/beam balance.
It is a scalar quantity & measured in kilogram (kg).
Mass is a fundamental quantity & is constant from place to place.

4. MEASUREMENT OF WEIGHT
Weight is the earth pull on a body or the downward force produced when a mass is in a
gravitational field.
The instrument used in measuring weight is spring balance.
It is a vector quantity & measured in newton (N).
Weight is a derived quantity & varies from place to place.
Relationship Between mass & weight
W=mg
Where: W=weight (N); m=mass (kg) & g=acceleration due to gravity (m/s2)

5. MEASUREMENT OF LENGTH
Length is simply distance extended. It is a fundamental quantity & measured in meters
(m).
Length can be measured using tape rule, meter rule, caliper, vernier caliper and
micrometer screw guage

6. MEASUREMENT OF TIME
Time can be defined as the interval between events.
It is a fundamental quantity & measured in seconds(s).
Time can be measured using stop watch/clock
