An object is rolling, so its motion involves both rotation and translation. Which of the following statements must be true concerning this situation? The rotational kinetic energy must be constant as the object rolls. The translational kinetic energy may be 0 joules. The total mechanical energy is equal to the sum of the translational and rotational kinetic energies and the gravitational potential energy of the object. The gravitational potential energy must be changing as the object rolls.
