Question

difference between fundamental unit and derived unit

Answer 1

derived units are made up of fundamental units. Fundamental units cannot be broken down into a different form. 

For example Distance (meters), Mass (kg), and Time (seconds) can not be broken down into a simpler form. While Force is measured in newtons (N) which can be broken down into its fundamental units of (kg * m) / s^2.

Answer 2

Fundamental units are the units of the fundamental physical quantities in SI system. They are not formed from other units. There are a total of seven fundamental units such as meter, kilogram, ampere, and second. Derived units are those units that are used for derived quantities.
