Freely Falling Body:
Any object is said to be falling freely if the only force acting on it is the gravitational force.
Conservation of Energy in a Freely Falling Body
The conservation of energy in a free fall means that the energy at all points during the fall is the same, that is, remains conserved as the ball falls. The potential energy is gradually converted into kinetic energy.. Let us prove it with an experiment.
