  1. 2. is also known as luminous energy
  2. 3. is the potential mechanical energy stored in the configuration of a material or physical system as work is performed to distort its volume or shape. The concept of elastic energy is not confined to formal elasticity theory which primarily develops an analytical understanding of the mechanics of solid bodies and materials
  3. 4. that part of the energy in a substance that can be released by a chemical reaction.
  4. 6. is the energy associated with the gravitational field.
  5. 8. the energy released by the nucleus of an atom as the result of nuclear fission, nuclear fusion, or radioactive decay. The amount of energy released by the nuclear fission of a given mass of uranium is about 2,500,000 times greater than that released by the combustion of an equal mass of carbon.

  1. 1. the energy possessed by a body because of its motion, equal to one half the mass of the body times the square of its speed.
  2. 3. is a potential energy associated with the conservative Coulomb forces within a defined system of point charges.
  3. 5. the difference between the total energy and the energy which would exist if no sound waves were presen
  4. 7. internal energy of a system in thermodynamic equilibrium (see thermodynamics) by virtue of its temperature. A hot body has more thermal energy than a similar cold body, but a large tub of cold water may have more thermal energy than a cup of boiling water.
