which of the following is a fundamental unit
A fundamental unit is a basic physical unit that is independent and cannot be derived from other units. Fundamental units are defined in the International System of Units (SI units).
The seven SI fundamental units are:
| Physical Quantity | Fundamental Unit | Symbol |
|---|---|---|
| Length | metre | m |
| Mass | kilogram | kg |
| Time | second | s |
| Electric current | ampere | A |
| Temperature | kelvin | K |
| Amount of substance | mole | mol |
| Luminous intensity | candela | cd |
Examples of Fundamental Units
metre
kilogram
second
Derived units such as newton, joule, and pascal are formed using fundamental units.
In conclusion, a fundamental unit is a basic SI unit that is not derived from any other physical unit.
