From the information about the computational model of energy changes experienced by an object in free fall, the most accurate conclusion is:
The total energy stays the same over time.
In a free fall scenario, the potential energy is converted into kinetic energy, but the total mechanical energy (potential energy + kinetic energy) remains constant if we ignore air resistance and other external forces.
