Energy Transformation through Circuits
| Term | Definition |
|---|---|
| chemical energy | the energy stored in the bonds of chemical compounds. Ex: batteries |
| electrical energy | the energy of charged particles called electrons |
| energy | the ability to do work or cause change |
| light energy | the energy of photons that travel in straight lines in waves; energy we can see |
| mechanical energy | the energy of motion and moving parts |
| sound energy | the energy of vibrations; energy we can hear |
| thermal energy | the total energy of moving particles that make up an object, observable in the object's state of matter and how it transfers heat |
| transform | to change form |
| circuit | a complete path around which electricity can flow |
| conductor | a material that allows electrical energy to pass through |
| current | the flow of electricity in a circuit |
| electrical conductivity | the ability of a material to allow electrical energy to pass through |
| insulator | a material that slows or stops the flow of electricity energy |
| output device | a component added to a circuit for energy transformations such as a lightbulb, motor, or bell |
| switch | a component in a circuit that controls the flow of electricity |
