| Conduction | transfer of thermal energy from one substance to another through direct contact |
| Temperature | measure of the average Kinetic Energy of the particles in an object |
| Geothermal | Thermal Energy that results from the heating of the earth's crust, also the reason why geysers occur |
| Energy | ability to do work |
| Friction | In every energy conversion energy is "lost" to thermal energy because of this |
| machines | have the ability to change the direction or amount of force but will never transfer more energy than you give it |
| Perpetual motion | machines of this type are impossible since energy is always "lost" |
| Coal | This fossil fuel is burned mostly for the generation of electricity |
| Nonrenewable resource | energy resource that cannot be replaced after they are used, or can only be replaced over thousands or millions of years |
| Potential Energy | Energy of position, or stored energy |
| Radiation | transfer of energy through matter or space as electromagnetic waves such as visible light and infrared waves |
| weight x height | The formula for calculating GPE |
| Absolute Zero | 0 Kelvin |
| Sound energy | caused by vibrations of air particles |
| Kinetic Energy | Energy of Motion |
| Heat | the transfer of energy between objects that are at different temperatures |
| Convection | transfer of thermal energy by movement of a liquid or gas |
| (mv2)/2 | formula for calculating Kinetic energy |
| Chemical Energy | "stored energy" the energy of food |
| Renewable resource | energy resource that can be used and replaced in nature over a relatively short period of time |
| Energy resource | natural resource that can be converted by humans into other forms of energy in order to do useful work |
| Nuclear energy | The suns energy, and the cause for all energy here on earth |
| Fossil Fuels | Energy sources that originally received their energy from the sun, but are formed by the buried remains of plants and animals that lived long ago |
| Energy Conversion | a change from one form of energy into another |
| Mechanical Energy | the total amount of energy in a system, or the sum of PE and KE |
