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 possessed by an object due to its motion or its position. Well, that seems simple enough, but what is energy? Energy is the ability to do work, where work is the movement of an object when a force is applied to it. For example, a person doing push-ups is doing work by applying force to the floor.
