| Question | Answer |
|---|---|
| Energy | The ability to cause objects to change, move, or work. |
| Energy Transformation | The change of energy from one type to another, such as potential to kinetic. |
| Heat | The movement of thermal energy from hot to cold. |
| Temperature | A measure of molecular motion, generally using a Fahrenheit (F) or Celsius (C) scale. |
| Thermal Energy | Energy that is transferred from a warm object to a cooler object. |
| Kinetic Energy | Energy of motion |
| Efficiency | The ratio of useful energy that is released by a process to the total energy absorbed by the process. |
| Law of Conservation of Energy | Energy can be transferred or transformed, but cannot be lost or destroyed. |
| Scientific Law | A phenomenon of nature that has been proven to occur repeatedly, whenever certain conditions exist. It is also called a natural law. |
| Chemical Energy | A type of potential energy where the energy is stored in the bonds of atoms. |
| Elastic Energy | Potential energy that is stored by stretching or compressing. |
| Electrical Energy | Movement of energy and charge from one place to another. |
| Light | A type of kinetic energy that is transferred by the rapid movement of electromagnetic fields. |
| Nuclear Energy | A type of potential energy that is stored in the nucleus of an atom. |
| Sound | A form of energy that is transferred through air, water and many solid materials by the vibration of an object. |
| Biomass | Material from living things, such as plants and animals, that is used as a source of fuel. |
| Electricity | The movement of electrically charged particles (electrons) from place to place. |
| Fossil Fuels | A fuel produced by living plant materials that have been buried and changed by heat and pressure under layers within the earth over billions of years of time. Natural gas, petroleum, and coal are examples of fossil fuels. |
| Generator | A machine for making electricity, generally by the circular movement of a turbine, driven by steam or water, connected to a magnet that evolves inside another magnet. |
| Hydroelectric Power | Energy is generated by moving water which turns the blades of a turbine, which generates electricity. |
| Nonrenewable Resource | Materials that cannot be easily or quickly replaced by natural systems, such as petroleum, coal, natural gas, and many minerals. |
| Power Plant | A facility that transforms energy into electricity and distributes it to the surrounding area. |
| Renewable Resource | A source of material that can easily be produced again and again in nature, such as wood, solar and hydroelectric power, and food crops. |
| Solar Energy | Energy that comes from the sun. |
| Turbine | Any of many machines that use kinetic energy from moving wind, water, steam, or gas to generate mechanical energy |
| Wind Energy | Energy from the wind that causes a turbine to turn in order to generate electricity. |
