Question

Explain whether the unit of work is a fundamental unit or a derived unit.

Answer 1

Answer:

Unit of work is Joule. Explanation: yes the unit of work is fundamental derived unit because 1joule is equal to the amount of work done in 1second.

Answer 2

Unit of work is a derived unit.

• We have fundamental units of mass, length, time, current, luminous intensity, etc. But we don't have any fundamental unit of work.

• So, we needed to derive the unit of work.

$[Work] = [force] \times [displacement]$

$\implies [Work] = kg \: m/ {s}^{2} \times m$

$\implies [Work] = kg \: {m}^{2} / {s}^{2}$

• kg m/s² is now known as Joule

$\implies [Work] = Joule$
