| part | a piece of a system that contributes to the whole process |
| input | something that is put into a system |
| process | a systematic series of actions directed to some end |
| output | The energy, power, or work produced by a system or device. |
| transferred energy | Work is done and energy is either stored or transferred to motion |
| kinetic energy | The energy of an object that is due to the object's motion. |
| potential energy | Stored energy because of position or in chemical bonds |
| mechanical energy | the amount of work an object can do because of the objects kinetic and potential energies |
| mass | a measure of the amount of matter in an object |
| Speed | the distance traveled divided by the time during the motion occured |
| work | The transfer of energy from one object to another, especially in order to make the second object move in a certain direction. |
| weight | A measure of the gravitational force exerted on an object |
| height | Distance from the ground. How tall someone or something is. |
| Joule | The standard unit of work or energy in SI, equal to the work done by a force of one newton when its point of application moves through a distance of one meter in the direction of the force. |
| Conduction | The transmission of heat or electricity or sound |
| Convection | The transfer of thermal energy by the circulation or movement of a liquid or gas |
| Law of Conservation of mass | Mass cannot be created or destroyed during ordinary chemical or physical changes. |
| radiation | The energy radiated or transmitted in the form of rays, waves, or particles. |
| thermal energy | Energy in the form of heat or heat transfer |
| electrical energy | Energy made available by the flow of electric charge through a conductor |
| chemical energy | That part of the energy in a substance that can be released by a chemical reaction |
| mechanical energy | the amount of work an object can do because of the objects kinetic and potential energies |

| nuclear energy | The energy from the changes in the nucleus of an atom |
| atom | smallest parts that make up a substance |
| molecule | A group of two or more atoms linked together by sharing electrons in a chemical bond. |
| Electron | An elementary particle with negative charge |
| Chemical bond | An electrical force linking atoms |
