Work, Potential Energy, Kinetic Energy, Torque -

\dpi{100} ML^{2}T^{-2}

 

- wherein

\dpi{100} N-m/Joule

 

 The dimension of work done and energy are same.

Dimension of work done =Dimension of Force x displacement =Dimension of Force x velocity x time

= Dimension of Force xacceleration x time x time

=FAT^2
