SUMMARY
The discussion centers on calculating rotational kinetic energy using the formula \( KE_{rot} = \frac{1}{2} I \omega^2 \), where \( I \) is the moment of inertia and \( \omega \) is the angular velocity. It is confirmed that angular velocity must be converted to radians per second (rad/s) for accurate calculations. The units of moment of inertia (kg m²) and angular velocity squared (1/s²) combine to yield energy in Joules (kg m²/s²), the standard unit of energy.
