building blocks of matter made up of protons, neutrons, electrons

have a positive charge and are found in the nucleus of the atom

have a negative charge and are found in an electron cloud (mostly a region of empty space)

have a neutral, or no charge, and are found in the nucleus of the atom

a property of a particle that affects how it behaves around other particles

a buildup of electric charges on an object

When do particles repel each other (or push away from each other)?

When the particles are the same charge (2 positives or 2 negatives)

when electrons jump from one object to another because they have a negative charge and are moving to a positively charged object; it causes a shock

a steady flow of charges that flow easily through wires

a material that resists the flow of electrons, like rubber and plastic

a material that readily allows electric charges to pass through, like metals and some liquids

a path along which electric charges can flow

a path or circuit that has no breaks in its path, allowing electric charges to flow

a path is broken when charges cannot flow; a switch controls the flow of charges by opening and closing the circuit

has only one path for electric charges to follow; if any part of the path breaks, the circuit is open and nothing works

a circuit with several different paths for the charges to follow; if one part of the circuit breaks, the charges can still flow along the parts

an object that attracts iron and a few other metals

a physical property of matter; produced by the motion of electric charges, such as electrons, which causes materials to attract or repel other objects

the space around the magnet where the force of the magnet acts

each magnet has 2 ends--one is north and the other is south; a magnetic pole is the part of the magnet where its magnetic field is the strongest

or N pole; two N poles will repel each other. An N pole and an S pole will attract to one another.

or S pole; two S poles will repel each other. An S pole and an N pole will attract to one another.

device in which current produces magnetism

a device that converts mechanical energy to electrical energy

Electricity

Question	Answer
atom	building blocks of matter made up of protons, neutrons, electrons
protons	have a positive charge and are found in the nucleus of the atom
electrons	have a negative charge and are found in an electron cloud (mostly a region of empty space)
neutrons	have a neutral, or no charge, and are found in the nucleus of the atom
electric charge	a property of a particle that affects how it behaves around other particles
static electricity	a buildup of electric charges on an object
When do particles repel each other (or push away from each other)?	When the particles are the same charge (2 positives or 2 negatives)
When do particles attract to each other?	When they are opposite charges
static discharge	when electrons jump from one object to another because they have a negative charge and are moving to a positively charged object; it causes a shock
electric current	a steady flow of charges that flow easily through wires
insulator	a material that resists the flow of electrons, like rubber and plastic
conductor	a material that readily allows electric charges to pass through, like metals and some liquids
circuit	a path along which electric charges can flow
closed circuit	a path or circuit that has no breaks in its path, allowing electric charges to flow
open circuit	a path is broken when charges cannot flow; a switch controls the flow of charges by opening and closing the circuit
series circuit	has only one path for electric charges to follow; if any part of the path breaks, the circuit is open and nothing works
parallel circuit	a circuit with several different paths for the charges to follow; if one part of the circuit breaks, the charges can still flow along the parts
magnet	an object that attracts iron and a few other metals
magnetism	a physical property of matter; produced by the motion of electric charges, such as electrons, which causes materials to attract or repel other objects
magnetic field	the space around the magnet where the force of the magnet acts
poles	each magnet has 2 ends--one is north and the other is south; a magnetic pole is the part of the magnet where its magnetic field is the strongest
north-seeking pole	or N pole; two N poles will repel each other. An N pole and an S pole will attract to one another.
south-seeking pole	or S pole; two S poles will repel each other. An S pole and an N pole will attract to one another.
electromagnet	device in which current produces magnetism
generator	a device that converts mechanical energy to electrical energy
