Q.
When an object falls toward the ground, it "loses" gravitational potential energy as its height decreases, and "gains" kinetic energy as its speed increases. In reality, it is neither gaining nor losing energy: as the object falls, its gravitational potential energy is transformed into kinetic energy.
