Success Criteria:
Objetive

• Students will speak about measurements
and give examples of areas studied by this
branch of physics.
Describe the use of rulers and measuring
cylinders to find a length or a volume
and how to measure a variety of time
intervals using clocks and digital timers

Making measurements
How length is measured?
Using a ruler
• A ruler (rule) is used to measure the
length of an object between 1mm and
1m.
What is the SI unit of length?
Metres, m.

5
How can you find the
volume of a regular solid?
By calculation.
• Use a ruler to measure
dimensions
• Use an appropriate equation to
calculate volume
CHAPTER 1 Coursebook page 3
6
Volume formula for geometrical figures
7
How can you find the
volume of an irregular solid?
By submersion.
• Fill a measuring cylinder with
water and read initial volume
• Submerge the object (hold
down if necessary) and measure
final volume
• The change in volume = volume
of object

8
How can time be measured?
Using clocks or stopwatches.
How can the accuracy of
measurements be increased?
By taking multiple measurements
and calculating an average.

How can very small
distances be measured?
Using a micrometer screw gauge
Or
Vernier calipers
