Question

how is dimensional formula of joule derived​

Answer 1

Answer:

Joule is the SI unit of work done. Therefore, the dimensional formula of Joule is the same as that of the work done. ... Work (Joule)= F × D = [M1 L1 T-2] × [L1] = [M1 L2 T-2]. Therefore, Joule is dimensionally represented as [M1 L2 T-2].

Answer 2

Explanation:

Joule is the Unit of Energy .

We know that the,

$energy = \frac{1}{2} m {v}^{2} \\ \\ m(l {t}^{ - 1} ) {}^{2} \\ \\ m {l}^{2} {t}^{ - 2}$
