The correct response is: The metal’s molecules are moving around. The metal’s molecules are moving around.
While the sphere might be stationary in terms of its center of mass, the individual atoms and molecules that make up the metal are constantly in motion due to thermal energy, which contributes to the kinetic energy at the microscopic level.
