Question

If momentum (P), Area (A) and Time (T) are taken as
fundamental quantities,then find the
Dimentional formula of Energy in term of PAT.​

Answer 1

Energy = Work. Dimensional formula of Work = M1L2T-2 [Check how Dimensional Formula of work is derived] Putting these values in above equation we get, Dimensional Formula of Energy = M1L2T-2. SI unit of Energy is Joule (J).
