Whay is the form of eventual total energy

The total energy of the ball is the sum of kinetic energy and potential energy, kinetic energy depends upon the velocity of the body, potential energy depends upon the position of the ball (height from the surface of the earth in gravitational potential energy), they keep varying but their sum i.e. total energy always remains constant.

Now eventually initially ball was at rest at a height h above the surface of the earth so form of energy was potential energy now as we know the Relation for Potential energy of an object of mass m due to earth’s gravity (g is acceleration due to gravity) held at a height h above ground is
