What are fundamental units and derived units?

Text Solution

Verified by Experts

Fundamental units:
The units in which the fundamental quantities are measured are alled fundamental units. It is also known as base units.
Derived units:
The units in which the derived quantitieks are measured are called Derived units.
Example:
Unit of speed `=("Unit of distance")/("Unit of time:)=m/s =ms^(-1)`
`ms^(-1)is a derived unit.
