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.
The energy acquired by the objects upon which work is done is known as mechanical energy. Mechanical energy is the energy that is possessed by an object due to its motion or due to its position. Mechanical energy can be either kinetic energy (energy of motion) or potential energy (stored energy of position).echanical Energy as the Ability to Do Work. An object that possesses mechanical energy is able to do work. In fact, mechanical energy is often defined as the ability to do work. Any object that possesses mechanical energy-whether it is in the form of potential energy or kinetic energy-is able to do work.
