Question

define fundamental unit with an example why it is the unit of force called a derived unit​

Answer 1

Force is a derived unit if the mass has been declared a fundamental unit. It is the force which imparts to the unit of mass the unit of acceleration. The derived unit of force is kg. m/s2.

Answer 2

•Fundamental quantity: Quantities which are independent on other physical quantity.

Example: length, mass, time, current, amount of substance, luminous intensity, thermodynamic temperature,

•Derived quantity: Quantities which depend on fundamental quantities.

Example: Area, volume, density, speed, acceleration, force, velocity etc

Force is a derived unit if the mass has been declared a fundamental unit. It is the force which imparts to the unit of mass the unit of acceleration. The derived unit of force is kg.m/s^2
