Which of the following statements are true? Select all correct. Question 9 options: The angular velocity omega has units of rad/s Rotational kinetic energy has different units than translational kinetic energy. Moment of Inertia has units of kg m2 If the center of mass of an object does not move, its kinetic energy must be zero. Kinetic energy of rotation depends on the direction of rotation. If they have the same mass and radius, a ring would have a larger moment of inertia about its center than a disc.
