Energy Density : It is defined as the amount of energy stored in a system or region of space per unit volume.
Energy Density =
Energy/volume.........(1)
Dimensional formula of Energy = M^1L^2T^(-2).......(2)
Dimensional formula of Volume =M^0L^3T^0.........(3)
putting these values((2)&(3)) in the equation (1). We get,
Dimensional formula of Energy Density =M^1L^(-1)T^(-2)
SI unit of Energy Density is Jm^(-3)(Joule per cubic meter).
