Question

GIVE TWO DIFFERENCE BETWEEN FUNDAMENTAL AND DERIVED QUANTITES.

Answer 1

Fundamental units are independently defined, and often the quantities are directly measurable in a physical system. Derived quantity: ... These units are not defined independently; they depend on the definition of other units. Quantities attached to derived units are called derived quantities.

Answer 2

answer:

Fundamental quantity

• does not depends on other quantities
• not defined in terms of other quantities

eg:- mass ,length

Derived quantity

• derived from fundamental quantities
• all quantities other than seven base quantities(length, mass, time, electric current, thermodynamic temperature, amount of substance and luminous intensity ) are derived quantities

eg:- area= length×breadth

speed= distance

time
