1 A farewell or final appearance, action, or work. 2  The beautiful legendary song sung only once by a swan in its lifetime, as it is dying.
A person converts chemical potential energy into kinetic/mechanical energy when he walks. The chemical potential energy usually takes the form of adenine triphosphate (ATP) st â¦ ored in the body.
Movement produces kinetic energy, which can be converted into power. In the past, devices that turned human kinetic energy into electricity, such as hand-cranked radios, computers and flashlights, involved a person's full participation. But a growing field is tapping into our energy without our even noticing it.
