Electricity
| Term | Definition |
|---|---|
| Atom | Tiny particles that make up matter |
| Proton | Particles in the nucleus of an atom that have a positive charge |
| Nuetron | Particles in the nucleus of an atom that have no charge |
| Electron | Tiny particles that move around the nucleus of an atom. An electron has a negative charge |
| Electric Force | Push or pull between charges objects |
| Attract | Pull together. Objects that have unlike charges attract |
| Repel | Push apart. Objects that have like charges repel |
| Electric Charge | A property of matter.( positive or negative) It can change when matter loses or gains electrons |
| Electric Discharge | When a charge moves quickly from one object to another |
| Friction | Rubbing together |
| Static Electricity | The build up of positive or negative electrical charges on an object |
| Lightning | A giant discharge of static electricity |
| Electricity | A form of energy associated with the movement of electrons |
| Conductor | Material through which electric current passes easily |
| Conductivity | The ability to conduct electricity |
| Insulator | Material through which electric current doesn't pass easily |
| Electric current | A flow of electrons through a circuit |
| Cell | The device in a circuit that provides the electrical energy. It could be a battery or electrical energy provide by outlets |
| Load | Is the component of the cell that uses thee electrical energy. It could be anything from a light bulb to a video game |
| Terminal | The place on the battery where electrons flow in and out |
| Battery | Two or more primary cells connected together, usually in series, to provide |
| Dry cell | A cell in which the electrolyte exists in the form of a paste, source of electric current; energy source |
| Switch | Can be used to open/close a circuit |
| Electric Circuit | Path electrons follow as they flow |
| Open Circuit | Is one in which the pathway of the electrical current is broken |
| Closed Circuit | Is one in which the pathway of the electrical current is complete and unbroken |
| Series circuit | Current can travel along only one path |
| Parallel Circuit | Has multiple pathways for the current to flow. If the circuit is broken the current may pass through other pathways and other devices will continue to work |
| Magnet | An object that can push or pull objects made of iron, nickel, or cobalt |
| Pole | Ends of a magnet where the force is the strongest |
| Attract | To pull towards (attraction) |
| Repel | To push away (repulsion) |
| Temporary Magnet | Material that has been magnetized, but will only stay magnetized for a short period of time |
| Permanent Magnet | Material that holds magnetic properties for a long time |
| Magnetic Field | Space around the magnet where the force acts |
| Electromagnet | A magnet made by winding a wire with a current around an iron bar. It is a temporary magnet and can be turned on and off |
