14. coherent, typically large body of matter with no definite shape.
15. Energy-Electrical energy is the power an atom's charged particles have to cause an action or move an object.
16. Energy-the energy released during nuclear fission or fusion, especially when used to generate electricity.

1. energy-of an object or material) able to resume its normal shape spontaneously after contraction, dilatation, or distortion.
2. Energy-the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.
4. Light energy is a kind of kinetic energy with the ability to make types of light visible to human eyes.
7. Energy-Mechanical energy is the energy that is possessed by an object due to its motion or due to its position.
9. ability to do work
