The following visual studies the transformation of energy: the potential energy of a body can be transformed into kinetic energy in another. Some energies are transformed into others of a different type.

The educational resource shows a visual about the conservation of energy: the sum of the kinetic energy and the potential energy of a body (mechanical energy) remains constant, provided there are no forces of friction.
