  1. 2. Energy (PE) - is the energy found in the nuclei of atoms.
  2. 5. Energy (PE) - the energy that an object has because of its position and is measured in Joules (J).
  3. 7. Energy (KE) - moving energy. It is the movement of tiny particles called electrons and protons. Electrical energy can be seen in nature in a bolt of lightning, which is a large number of electrons flowing through air all at once.
  4. 9. Energy (KE) - Sound is energy that we can hear. It is a type of kinetic energy made from matter's vibration. Sound moves from the source of its vibration through other matter, like air or water.
  5. 12. Energy (PE) - the energy that is needed to move a charge against an electric field.
  6. 13. - a device consisting of a hub fitted with blades that is made to turn rapidly by an engine.
  7. 15. - a substance that does not possess a definite shape and easily yields to external pressure. Fluid is any liquid or gas or any material that is unable to withstand a shearing or tangential force, when at rest.
  8. 17. Energy (PE) - energy stored in the bonds of atoms and molecules. Batteries, biomass, petroleum, natural gas, and coal are examples of chemical energy.
Down
  1. 1. Energy (KE) - the energy of motion. All moving objects have kinetic energy.
  2. 3. Energy (PE) - energy stored in the bonds of atoms and molecules. Batteries, biomass, petroleum, natural gas, and coal are examples of chemical energy.
  3. 4. Energy (KE & PE) - all the energy that an object has because of its motion (kinetic energy) and its position (potential energy)
  4. 6. - a machine that transforms rotational energy from a fluid that is picked up by a rotor system into usable work or energy.
  5. 8. of Energy - a principle stating that energy cannot be created or destroyed, but can be altered from one form to another.
  6. 10. Energy (KE) - the energy contained within a system that is responsible for its temperature.
  7. 11. Energy (PE) - the energy that is needed to move a charge against an electric field.
  8. 14. Transformation- the changing of energy from one type to another, e.g. from kinetic energy to electrical energy, or from potential energy to kinetic energy.
  9. 16. Energy (KE) - the physical energy resulting from electromagnetic radiation, usually observed as it radiates from a source into the surrounding environment. Radiant energy sources include the entire electromagnetic radiation spectrum, including gamma rays, x-rays, radio frequencies, microwaves, light and heat.
