How many kind of physical quantities?
Answers
In terms of physics, the quantities can be classified into two types.
They are Fundamental and Derived Quantities.
Fundamental Quantities
The quantities that do not depend on any other physical quantity for their measurement are known as fundamental quantities. These quantities do not take support of other physical quantities for its measurement. There are only 7 physical quantities. And rest of all other quantities are derived quantities. They are listed below:
- Mass
- Length
- Time
- Temperature
- Electric current
- Luminous intensity
- Amount of substance
Derived Quantities
The Physical quantities that depend upon other physical quantity for its measurement are known as derived quantities. The measurement of derived quantities directly depends upon other quantities. So in order to measure the derive quantity, one must measure the quantities that it depends upon.
Except 7 fundamental quantities, all other quantities are derived quantities.
Answer:
Physical quantities are those quantities that can be measured. Basically, there are two types of physical quantities (Base quantities or fundamental quantities) and (Derived quantities).
