Final answer:
A slow-moving freight elevator exhibits both kinetic and potential energy, but is primarily characterized by kinetic energy due to its motion.
Step-by-step explanation:
A fully loaded slow-moving freight elevator is an example of both kinetic energy and potential energy. Kinetic energy is the energy of motion, which in this case is due to the elevator's movement, even when slow. Potential energy, on the other hand, is stored energy; for an elevator, it's related to its height above the ground so even when an elevator moves slowly, if it's not on the ground floor, it has potential energy due to gravity's pull on it. But if we have to choose one predominant type of energy for a slow-moving elevator, we would consider kinetic energy, as it is actively moving.
