  1. 2. Nuclear power, or nuclear energy, is the use of exothermic nuclear processes, to generate useful heat and electricity. The term includes nuclear fission, nuclear decay and nuclear fusion.
  2. 4. is a place in a longitudinal wave where the particles are close together
  3. 5. In the physical sciences, mechanical energy is the sum of potential energy and kinetic energy. It is the energy associated with the motion and position of an object. The principle of conservation of mechanical energy states that in an isolated system that is only subject to conservative forces the mechanical energy is constant.
  4. 7. is the energy that is stored by the forces within a distorted elastic object.
  5. 9. means to reduce the quantity of energy that is used for different purposes. This practice may result in increase of financial capital, environmental value, national and personal security, and human comfort.
  6. 10. Solar energy is radiant light and heat from the sun harnessed using a range of ever-evolving technologies such as solar heating, solar photovoltaics, solar thermal energy, solar architecture and artificial photosynthesis.
  7. 12. Electromagnetic radiation (EM radiation, EMR, or light) is a form of energy released by electromagnetic processes. In physics, all EMR is referred to as light, but colloquially light often refers exclusively to visible light, or collectively to visible, infrared, and ultraviolet light.
  8. 14. usable power that comes from heat, electricity, etc
  9. 16. is the potential of a chemical substance to undergo a transformation through a chemical reaction or, to transform other chemical substances. Examples include batteries, light bulbs, cells, bombs and more. Breaking or making of chemical bonds involves energy, which may be either absorbed or evolved from a chemical system.
  10. 17. In physics, potential energy is the energy stored in an object due to its position in a force field or in a system due to its configuration. Common types include the gravitational potential energy of an object that depends on its vertical position and mass, the elastic potential energy of an extended spring, and the electric potential energy of a charge in an electric field
  11. 18. BIOMASS is a planned ESA satellite that is due for launch in 2020 under Living Planet Programme, aimed to take measurements of forest biomass to assess terrestrial carbon stocks and fluxes.
Down
  1. 1. wave in which the vibration of the medium is parallel to the direction the wave travels
  2. 3. Electromagnetic radiation (EM radiation, EMR, or light) is a form of energy released by electromagnetic processes. In physics, all EMR is referred to as light, but colloquially light often refers exclusively to visible light, or collectively to visible, infrared, and ultraviolet light.
  3. 6. In the physical sciences, mechanical energy is the sum of potential energy and kinetic energy. It is the energy associated with the motion and position of an object. The principle of conservation of mechanical energy states that in an isolated system that is only subject to conservative forces the mechanical energy is constant.
  4. 8. transverse wave is a moving wave that consists of oscillations occurring perpendicular (or right angled) to the direction of energy transfer. If a transverse wave is moving in the positive x-direction, its oscillations are in up and down directions that lie in the y–z plane. Light is an example of a transverse wave.
  5. 11. In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes
  6. 12. is a zero-emission fuel which uses electrochemical cells, or combustion in internal engines, to power vehicles and electric devices
  7. 13. energy made available by the flow of electric charge through a conductor
  8. 15. are fuels formed by natural processes such as anaerobic decomposition of buried dead organisms. The age of the organisms and their resulting fossil fuels is typically millions of years, and sometimes exceeds 650 million years. Fossil fuels contain high percentages of carbon and include coal, petroleum, and natural gas.
