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.
Mechanical energy can take the form of kinetic energy as in the energy of an object's movement or it can take the form of potential energy by virtue of the stored energy of an object in a particular position. Mechanical energy can be seen in the form of a pendulum, landslides, and avalanches etc.
