The transformation of energy when the body falls.

When the body falls, the following energy transformation occurs:

First, at the highest point of its trajectory, the body has a potential energy equal to Epotential = m * g * H (where m is the body mass, g is the acceleration of gravity, H is the height above the earth’s surface) and zero kinetic energy Ekinetic = 0 ( since the speed of the body is zero). As the body freely falls to the ground, its speed increases along with the kinetic energy, and the height above the earth’s surface decreases, that is, the potential energy decreases. As the fall, the potential energy is converted into kinetic, and at the very surface of the earth immediately before the impact, the potential energy is zero, and the kinetic energy is Ekinetic = m * v ^ 2/2 (where v is the body’s velocity.).

The transformation of energy occurs due to the law of conservation of energy, which is generally described by the following formula:

Epotential + Ekinetic = const, that is, the sum of all energies of the body is always constant.

When describing the transformation of energy upon falling, the force of air resistance was not taken into account. If this force is also taken into account, then part of the energy will be transferred into the internal energy of the body, since due to resistance it will heat up.
