The transformation of potential energy into kinetic energy is described through the process of energy conversion. In physics, potential energy is stored energy that has the potential to do work, such as an object at a height (gravitational potential energy). When this object falls, the stored potential energy is converted into kinetic energy, the energy of motion. This principle is fundamental to various natural phenomena and is observable in many systems, such as mechanical systems involving falling objects, as well as in biological systems like animals moving in response to environmental stimuli.
