under free fall when a body Falls due to the expression of gravity is height decreases so the potential energy
also under the influence of acceleration due to gravity the velocity increases hence the kinetic energy this change occurs simultaneously
and as we know that the mechanical energy of a substance is always remains constant
so it is cleared then potential energy is converted into kinetic energy during free fall
and at the end height become 0 so potential energy is zero
and the velocity is maximum at the last moment so the kinetic energy is the maximum
hence the all potential energy which was in the body has completely changed into kinetic energy
