Energy Unit Vocab.
what energy does.... unit
| Term | Definition |
|---|---|
| acceleration | an increase in the rate or speed of something |
| chemical energy | the energy involved in the bond formed between two atoms; type of potential energy stored in chemicals |
| circuit | a complete path of conductors that an electric current can flow through |
| closed circuit | a complete electrical connection in which current can flow in an uninterrupted path |
| collision | an instance of one object exerting force upon another, causing an exchange of energy |
| conductor | a material that allows heat energy or electricity to pass through it easily |
| constraint | a limitation or restriction; a rule that you cannot break or something that you cannot do while solving an engineering problem |
| criteria | a standard of judgment; a rule for evaluating or testing something |
| device | something made or adapted for a particular purpose |
| distance | the amount of space between two people or things |
| electrical current | a constant flow of electrons through a conductor |
| electrical energy | an electric charge that lets work be accomplished |
| electricity | a form of energy that is produced when electrons move from one place to another place |
| energy | the ability to do work |
| energy form | any of the different types of energy that measure the ability of an object or system to do work |
| engineering design cycle | a series of steps that engineers follow to come up with a solution to a problem |
| friction | a force between two surfaces rubbing against each other; friction works against motion |
| heat | a form of energy associated with the movement of atoms in any material. The higher the temperature, the faster the atoms are moving and the greater amount of energy present; the quality of being hot |
| hydropower | electricity or power produced by the energy of falling or rapidly moving water |
| insulator | a material that does not let heat energy or electricity pass through it easily |
| kinetic | pertaining to motion |
| motion | a change in the position of an object |
| nonrenewable energy | a natural resource that cannot be replaced |
| nuclear energy | the energy released during a nuclear reaction |
| open circuit | an electrical circuit that is not complete |
| potential | having the ability to develop into something; (energy) the energy an object has because of its position rather than its motion |
| rate | a comparison of two values that are measured in different units |
| receiver | a person or device that is getting the information |
| relative speed | measurement of speed in relation to another object |
| renewable energy | energy from a source that is not depleted when used |
| solar energy | energy from sunlight |
| sound | a form of energy produced by vibrating objects |
| source | a thing or plan from which something comes |
| speed | the distance an object moves per unit of time, such as miles per hour |
| switch | a device that opens and closes an electric circuit to stop and start the flow of electrons |
| thermal energy | the internal energy of an object due to the kinetic energy of its atoms |
| transfer | to pass from one place to another |
| transformation | the process of changing the form, appearance, or character of something |
| wind energy | energy in which turbines convert kinetic wind energy into energy that can be used for power |
