 Consider a baton that is being twirled in a circle in someone's hand. As the baton is twirled, each atom in the baton moves in a circle at a speed that depends on how far the atom is from the center of the baton. You could add up all the individual velocities of the atoms to get the total kinetic energy of the baton. This is fairly simple (but painful) to do. The kinetic energy of atoms on either side of the center (but at the same distance from it) has the same kinetic energy because they move at the same speed. Consider a baton that is being twirled in a circle in someone's hand.
