Derived Quantities
The purpose :1. Able to mention the derived
quantities2. Able to give the example of
derived quantities3. Able to determine the volume of
solid
Derived quantities are quantities derived from basic quantities
Several examples of derived quantities
Area Square meters m2
Volume Cubic meters m3
Velocity meters per second m/s
Density Kilograms per cubic meters Kg/m3
Area is derived quantity which is obtained by multiplying two length quantities
Volume , similar to area, volume is also derived of basic quantities. That is the productOf three length quantities
Solids which have uniform shape such asCube, volume can be calculated by using Certain formula.
Meanwhile solids which have non uniformShape such as stone, its volume can be calculated directly.
How the methods
a.Fill the measuring glass with wather
It is called initial volume
b. Then, put a stone that will be measured into the measuring glass
The volume of water and the stone are called the final volume
So, the volume of stone = final volume – initial volume
CONCLUSION
• Derived quantities are quantities derived from basic quantities.
• Example : area (m2), volume (m3), velocity (m/s), density(kg/m3),etc
• The vollume of thing = length x length x length, and can be measured using a measuring glass
