Which physical quantities are represented by the following ?
i) Product of moment of inertia and the angular velocity:
ii) Product of moment of inertia and the angular acceleration.

Explanation

i) Since angular momentum, `L = Iomega`
Thus, physical quantity represented by the product of moment of inertia and angular velocity is angular momentum.
ii) Since torque, `tau = Ialpha`
Thus, physical quantity represented by the product of moment of inertia and angular acceleration is torque.
