When an object falls toward the ground due to gravity, what type of energy becomes kinetic energy?

potential energy (gravitational)

Explanation:

Potential energy is the energy that is stored in an object due to its position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height. If we think of the ground as the zero height, the height of the object is coming down from a positive height.  Wherever it is relative to the zero height, it is stored at that height, meaning that it is potential energy at that particular height.  When it moves to the ground, it becomes kinetic, by gravitational means.
