"Energy" is divided into two sections, "i. Potential" and "ii. Kinetic". According to the Law of Conservation of Energy, one cannot get more energy out of something than was put into it, thus both track movements are exactly equal in length.
While listening to "i. Potential", one can imagine the build-up of energy as if an object were being hoisted higher and higher into the air.
When the music instantly changes pace and becomes quite frantic, "ii. Kinetic" begins. One can then imagine the hoisted object being dropped from its highest point, causing the forces of gravity pull it straight to the ground as it gradually gains velocity. The track's abrupt ending depicts the object's instant loss of velocity as it slams into the ground.
