Kinetic energy is "stored" energy. It's the amount of energy it took to move an object from rest to motion. That energy is then "stored" in the object until it is acted upon, because energy can not be destroyed, only converted. In this case, the kinetic energy of the spheres is converted to heat energy when they are rapidly decelerated, that is, brought to a stop by smashing together.
