experiments
100
the law that states opposite charges attract one another and like charges repel. (example 2 + charged ballons repel one another)
What is law of electric charges
100
this is a type of charging that occurs when charges are wiped from one object to another
What is friction
100
the term static is an synonym for what
static means not moving
100
the release of electric energy stored in an object
What is electric discharge
100
electricty is the flow of this
What is electrons
200
the area of influence around a charged object
What is electric field
200
This is the only type of charge that does not require direct contact
What is induction
200
a material which charges cannot flow through easily
What is an insulator
200
what is happening if your hair stands up on end outside
you are in a location that is being charged by induction, you are about to be struck by lightning.
200
why was it necessary for the charged person to stand on the platform in the Vandegraffe experiment?
they would not build charge if they were in contact with the ground.
300
Force of attraction or repulsion based on an objects charge
What is electric force
300
When using the van de graff generator placing your had directly onto the dome will result in this kind of charging
What is conduction
300
the build up of charges in an object
What is static electricity
300
What will happen to the bark on a tree that has been struck by lightning. what causes these trees to explode?
What is blow off chunks in a spiral pattern, burn vapor pressure of the water turning to water vapor inside the tree, causes the tree to explode, like a hot dog in a microwave.
300
what were the bubbles a good example of ?
What is attraction/repulsion of charges
400
Name the Positively, negatively, and neutrally charged subatomic particles
What is Proton, electron, neutron
400
When you leave your clothes in the dryer the charge eventually goes away. Were the charges destroyed?
No, charges cannot be created or destroyed, they simply move from one atom to another
400
one of the most dramatic examples of electric discharge
What is lightning
400
What is the zigzag line and why is it important to us as we study electricity
the line that separates medals from nonmetals on the periodic table. this line also separates conductors and insulators
400
when the smoke was around the genorator what did it show
What is an electric wind.
500
Name the two things that affect electric force
What is the amount of the charge and the distance between charges(the greater the charge the greater the electric force)
500
What makes metals good conductors
they have electrons in their outer shell that are free to move, thus allowing electricity to flow
500
a lightning rod does two things for a building. use class disscussion and the Van De Graaf demonstration to support your answer
a lighting rod reduces a buildings likely hood of being struck by reducing charges building in the ground. it also protects the building and occupants by providing a safe path of electricity to the ground.
500
the build up of elec charges in clouds is cased by what
friction between particles of ice,air and water
500
what did you stop hearing when a lighting rod was attached to the generator
What is the sound of electric discharge
