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 is the energy which is possessed by an object due to its motion or its stored energy of position. Mechanical energy can be either kinetic energy (energy of motion) or potential energy (stored energy of position).hat is, its mechanical energy enables that object to apply a force to another object in order to cause it to be displaced. Numerous examples can be given of how an object with mechanical energy can harness that energy in order to apply a force to cause another object to be displaced.
