The aerial acrobatics of the Russian Barre routine require exquisite balance, timing, and years of training. That’s not enough though; conservation of energy plays a big role as well. At the top of the jump, Anna’s energy is entirely potential, but, as she falls, her energy turns kinetic. Landing on the barre, the energy changes form once more, stored as elastic energy in the bending barre. In this unit, students can learn the basics of these three common forms of energy.
