Fundamental Physical Quantities : The Building blocks of Measurement
The building blocks of physics are the physical quantities in terms of which the laws of physics can be expressed.
All quantities which can be measured either directly or indirectly are called physical quantities, such as length, time, mass, temperature, speed, force, electric current, etc.
Physical Quantities are divided into two classes:
- Fundamental Quantities and
- Derived Quantities
Examples of fundamental quantities are length, mass and time.
Length is a Fundamental Quantity
Mass is a fundamental Quantity
Time is a Fundamental Quantity
Images: Length mass and time are fundamental quantities
Speed is an example of derived quantity as it is derived from the measurement of length and time.
