Which one of the following is not measured in units of energy ?

A. $${\text{Couple}} \times {\text{angle}}$$

B. $${\text{Moment of inertia}} \times {\left( {{\text{angular velocity}}} \right)^2}$$

C. $${\text{Force}} \times {\text{distance}}$$

D. $${\text{Impulse}} \times {\text{time}}$$

Answer : $${\text{Impulse}} \times {\text{time}}$$

Solution :
$${\text{Unit of}}\,\,{\text{impulse}} \times {\text{time}}\,{\text{ = }}\left( {kg\,m{s^{ - 2}} \times s} \right) \times s = kg\,m$$
