Now, consider that this baton is now tossed into the air while it twirls. The whole baton is moving up with a known speed. The kinetic energy of the baton has increased because the baton is both translating and rotating.((Translation is motion that you have worked with in the past. It is the motion of point particles, no rotation or oscillation, | Now, consider that this baton is now tossed into the air while it twirls. The whole baton is moving up with a known speed.

- | Consider a pair of atoms that are the same distance from the center of the baton (red circles in figure to the left). At this instant, the atom on the right is moving up as the baton rotates. The atom on the left is moving down. Relative to the fixed frame of the ground, the atom on the right, at this instant, is moving faster than the atom on the left.
