Just before an object reaches the ground, its gravitational potential energy is nearly zero because its height is minimal. Conversely, its kinetic energy is at its maximum due to the object’s maximum velocity. The total mechanical energy, initially all potential energy, has entirely converted into kinetic energy, assuming negligible air resistance.
At the start of its fall, the object's kinetic energy is zero because its initial velocity is zero. All of its mechanical energy is in the form of gravitational potential energy, which then transforms into kinetic energy as it falls.
