MEASUREMENT TECHNIQUES
-
-
- It is coloured to increase visibility
-
-
-
-
- m^2 and cm^2 are normally used
- To calculate this, use a formula,
depending on the shape
- Place the object on a square grid and trace
it. Count the number of more than half filled
squares to be the area
- To be more accurate, use a
smaller grid
- m^3 and cm^3 are normally used
- To calculate this, use a formula,
depending on the solid
- Fill a measuring cylinder to a certain amount of water and
lower the solid in. The increase of the water level is the volume
- kg and g are normally used
-
-
- Don't measure races to the point of 0.01s,
because the reaction time might lag
- Types of Measurement Tools
- For long intervals of time
- Most depend on quartz crystals for accurate timing
-
- Up to an accuracy of 0.01 seconds
- Up to an accuracy of 0.1 seconds
- For long intervals of time
- The pendulum swings and the gravitational
potential energy is converted into elastic
potential energy.
- An oscillation is when a
pendulum swings from one
point and back
- The time for a complete
oscillation is called one period
-
- Includes Length, Mass, Time, etc.

-
- To simplify huge or minuscule
quantities, an alternative
- They increase/decrease by
thousands, most of the time
- E.g., From kilo(10^3) to mega(10^6)
-
- No measurement is perfectly accurate
- They are inconstant errors, e.g., time of one oscillation
- A consistant error in measuring, e.g., measuring
without adding/deducting the zero error.
- The eye is not aligned with the measuring tool
OR the object is not aligned with the scale
- Read the measurement (length) when...
- Your eyes are perpendicular to the scale
- The object is aligned properly with the ruler
- Types of Measurement tools
(Please note that I own none
of the videos)
-
-
- For longer length (depends, usually ≥3m)
- For an accuracy of 0.01cm
-
-
- Mark it against the Vernier Scale (0.0cm)
- Measure the length (0.00cm)
-
- Note: Some part names in
the video are different
from mine. Follow mine.
-
- For an accuracy of 0.01mm
- The little tip at the end of the frame
- The spindle and the anvil
clamp on the object that is
being measured
- The main scale is on the it
- The circular scale is on it
- Prevents the spindle from over screwing
- Please note that the anvil is at
the point where the spindle
reaches the end, the little tip.
The video marked the frame
as the anvil, that is wrong.
-
-
- A product of base quanitities
-
- volume= length x width x height
- force= mass x accelaration
- Consists of a magnitude and unit
- m^3 and cm^3 are normally used
- To calculate this, use a formula,
depending on the solid
- Fill a measuring cylinder to a certain amount of water and
lower the solid in. The increase of the water level is the volume
