# Electricity

### Electrical, Magnetic, and Gravitational Forces

TermDefinition
Element A substance in which all of the atoms are identical.
Electron The negatively charged part of an atom.
Charge An electrical force within an atomic particle.
Electricity The flow of electrons.
Static Electrons that jump form object to object.
Magnetic Field The force field created between the poles of a magnet.
Load A device that does work in an electrical circuit.
Circuit A path through which electricity travels.
Magnet An object where one end has electrons that move in one direction and the other end has electrons move in the opposite direction.
Generator A device with magnets and coils of wire that produces electricity.
Battery A device that produces electricity through a chemical reaction.
Repel How like charges or magnetic poles respond.
Attract How unlike charges or magnetic poles respond.
Mass The amount of matter an item contains. Measured in Kilograms. STAYS THE SAME!
Weight A force caused by gravity. Greater the mass, the greater the weight will be. Measured in Newtons. WEIGHT CAN CHANGE!
Gravity Force that attracts objects towards each other.
When do gravitational forces increase? When the masses are bigger and when the objects are closer.
What happens when a switch in a circuit is open? The flow of electricity stops.
What happens when a switch in a circuit is closed? There is a flow of electricity.
If you have an object that is 300 kilograms on earth, what will its weight be on the moon. Moon = 1/6 the gravity on earth. 300 kilograms divided by 6 is 50 kilograms.
If you have an object that has a mass of 23 Newtons, what will its mass be on the moon. Since mass stays the same, no matter where it is measured, it is 23 Newtons.
Which direction does a compass in always point? Why? North. The north seeking pole of the compass is attracted to the north pole of earth.
Magnetism The force of attraction or repulsion in and around a material.
Force An interaction, that when unopposed, will change the motion of an object.
Friction A force that works against motion.
Unbalanced Force A force that produces a change in motion.
Newton The standard unit of force.
