Question

$kg{m}^2{s}^{-2}$ represents the unit of

• A. Kinetic energy
• B. Work done
• C. Potential energy
• D. All the above

Answer 1

The correct option is D All the above

$kg{m}^2{s}^{-2}$ is unit of energy and all these given in option are energy in different form so all will have same unit.

i am showing it deriving for one.

kinetic energy $\frac{1}{2}m{v}^2=kg.m^2{S}^{-2}$

hence answer is option D.
