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
