Comment on the statement "Rotational kinetic energy is equal to half of the moment of inertia into angular velocity"

The acceleration from Newton’s second law is equal to the final velocity divided by the time and the average velocity is half the final velocity, showing that the work done on the block gives it kinetic energy equal to the work done. In Newtonian rotational physics, angular acceleration is inversely proportional to the moment of inertia of a body. The kinetic energy of a rotating object depends on the object’s angular (rotational) velocity in radians per second, and on the object’s moment of inertia.
