Rotational Kinetic Energy Practice Test

A uniform rod rotates about a fixed axis through its center, perpendicular to the rod. The rod’s angular speed increases while its mass distribution stays unchanged. What happens to its rotational kinetic energy?​

A uniform disk rotates about its central axis. It is replaced by a different object that has the same mass and angular speed $\omega$ but a larger moment of inertia about the same axis. The rotational kinetic energy of the new object is
