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.
Unit 26 Types of Energy Energy can neither be created nor destroyed. Energy changes from one kind to another. The total energy of an object never changes. Anything that has mass and movement has kinetic energy.The kinetic energy of an object in this case is given by the relation: KE = (1/2)mv2 m=mass of the object V=velocity of the object The greater the mass or velocity of a moving object, the more kinetic energy it has.ind power uses mechanical energy to help create electricity. Potential energy + Kinetic energy = Mechanical energy Mechanical Energy Summary Gravitational PE Elastic PE The energy of motion mgh Energy that is stretched or compressed.
