write physical significance of moment of inertia. show that K.E = 1/2 (TW^2)

 Answer:

Physical importance of the moment of inertia:

1. The moment of inertia has the same physical significance as a mass in translational motion.
2. The mass of a body is used to calculate inertia in translational motion.
3. Inertia increases with increasing mass.
4. The force required to generate linear acceleration will also rise.
5. In rotational motion, the greater the moment of inertia, the greater the angular acceleration.
