Question

what is the difference between a fundamental quantity and a derived quantity​

Answer 1

Answer:

Fundamental Quantities are independent and don’t depend upon other quantities for their measurement. On the other hand, derived quantities depend upon other fundamental quantities for their measurement.

for example: Mass is a fundamental physical quantity. It’s SI unit is Kg.

Speed is a derived physical quantity. It’s unit is m/s (meter per second). So, speed depends upon length and time for being measured.
