- 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.
