Question

If I is the moment of inertia and ω the angular velocity, what is the dimensional formula of rotational kinetic energy $\frac{1}{2}I\omega^{2}$?
(a) [ML²T⁻¹]
(b) [M²L⁻¹T⁻²]
(c) [ML²T⁻²]
(d) [M²L⁻¹T⁻²]

Answer 1

C is the correct answer.

After all it is the energy. All forms of energy has same dimensional formula
