3. In physics, energy is the quantitative property that is transferred to a body or to a physical system
5. radiant energy is the energy of electromagnetic and gravitational radiation.
7. spans a broad spectrum from very long radio waves to very short gamma rays.
10. Chemical energy is the energy of chemical substances that is released when the substances undergo a chemical reaction and transform into other substances.
14. In physical sciences, mechanical energy is the sum of potential energy and kinetic energy.
15. In physics, potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors.
16. the energy is given by the machine to do useful work
17. the energy transferred to or from an object via the application of force along a displacement.
18. Elastic potential energy is energy stored as a result of applying a force to deform an elastic object.

1. In physics, the kinetic energy of an object is the form of energy that it possesses due to its motion.
2. Nuclear power is the use of nuclear reactions to produce electricity. Nuclear power can be obtained from nuclear fission
4. The joule is the unit of energy in the International System of Units.
6. Electrical energy is energy related to forces on electrically-charged particles and the movement of those particles.
8. the quantity of motion of a moving body, measured as a product of its mass and velocity.
9. a comparison of the energy output to the energy input in a given system.
11. The first law of thermodynamics is the expression of the principle of energy conservation, and it considers energy as a thermodynamic property.
12. the force by which a planet or other body draws objects toward its center.
13. In physics, the term conservation refers to something which doesn't change.
16. the amount of energy supplied to the machine.
