Question

Rotational kinetic energy is equal to

Answer 1

= the final angular velocity divided by the time and the average angular velocity is equal to half the final angular velocity.

Answer 2

6Rotational energy or angular kinetic energy is kinetic energy due to the rotation of an object and is part of its total kinetic energy. It is given by:

$e = \frac{1}{2}i {v}^{2}$
is rotational kinetic energy,{\displaystyle \omega \ } is angular velocity,{\displaystyle I\ } is moment of inertia around the axis of rotation.
