How si unit joule can be derived by fundamenal units?

Answer 1

You mean joule to be given in terms of fundamental units such as m, kg and s

Now joule is the scientist's name and it is the unit of work.

Work = force x displament

So J = N m

But N stands for newton another scientist's name.

But force = mass x acceleration

But acceleration = velocity / time and velocity = displacement / time

So acceleration has ms-2 as unit.

So N = kg x m s-2

Hence J = kg m2 s-2
