# What is Dimensional Formula of Energy?

Posted in Dimensional Formulae | Email This Post |Energy is defined as ability to do work.

Mathematically,

Energy = Work.

Dimensional formula of Work = M^{1}L^{2}T^{-2} [Check how Dimensional Formula of work is derived]

Putting these values in above equation we get,

**Dimensional Formula of Energy = M ^{1}L^{2}T^{-2}**

SI unit of Energy is Joule (J)

energy = work

and work = Mgh

energy = [M]*[LT^-2]*[L]

= ML^2T^-2

Thanks great help
