Term | Definition |
---|---|
Attraction | The electric force exerted by oppositely charged particles, tending to draw or hold the particles together. |
Chemical energy | Energy that is stored in matter and can be released by a chemical reaction. |
Circuit | An looped path of conductors in which electrical energy can flow freely. |
Conduct | To transmit heat, sound, or electricity through a medium. |
Conductor (electrical) | A material that readily allows electric charges to pass through it and therefore carries electricity well. |
Insulator | A material used to reduce or prevent the transfer of electricity, heat, or sound. |
Electrical energy | Energy made available by the flow of electric charge through a conductor. |
Electricity | The flow of electrons. |
Energy | The capacity to do work |
Heat energy | Energy that transfers between substances because of a temperature difference between the substances. |
Light energy | The only visible form of energy; produced or given off directly from the Sun, bulbs, and lasers. |
Mechanical energy | The energy that is possessed by an object due to its motion or position. |
Repel | To force away or apart. The opposite of attract. |
Sound energy | Energy produced by sound vibrations. |
Conductor (heat) | Substance that allows heat to pass through it easily. |
Closed circuit | A complete loop where the switch is closed and electrons/electricity can flow easily |
Open circuit | An incomplete loop where the switch is open or wires are not connected correctly and electrons cannot flow |
Potential energy | energy that is stored to be used later |
Kinetic energy | energy of motion |
Refract | light is bent such as through a different medium (pencil through air then water) |
Reflect | light is bounced off an object like on a mirror |
