Question

what is a derived unit . Give reason

Answer 1

Answer:

A derived unit is a unit that is based on some other fundamental or derived unit.

Example:

The unit of force, newton (N) is a derived unit as it is based on the units of mass and acceleration. In this scenario mass is a fundamental unit and acceleration is another derived unit (as it is based on units of velocity and time).

1 N = 1 kg * 1 $m$ $s^{-2}$
