Lightning
Within a storm cloud, warm air rises past falling cold air, and these are picked up by the cold air that is filled with hail, ice and partially frozen water droplets.
What are electrons?
These particles have a negative charge, and two of them will repel each other.
What is an electron?
Iron, sodium, sea water.
What is a conductor?
These two variables determine the strength of the electrical force between two objects
What is the amount of charge on both objects and the distance between two objects?
When conducting objects with unequal charge, electrons flow from the object with greater concentration of negative charge until the concentration of charge on both objects is equal by this process.
What is conduction?
The negatively charged cloud causes the Earth's surface to repel which particle?
What are electrons?
These particles have no charge.
What is a neutron?
Plastic, rubber, and pure water
What is an insulator?
If the total amount of charge on two objects increases, there is an increase in the attraction between them because of this.
What is an increase in electric force?
When you bush your hair and it sticks up until you touch someone and a spark flies, this is happening.
What is electric discharge?
The Earth's surface below a lightning cloud has what charge because of the electrons on the bottom of the cloud?
What is postive?
These have a positive charge and two will repel each other.
What is a proton?
Transferring charge by this process by which one object causes two other objects that are conductors to become charged without touching.
What is induction?
Your brush can be positively charged after bushing your hair and your hair can be negatively charged. When you bring them close together, the electric force does this.
What is attract?
When you touch the Van de Graaff generator with another metal ball, you can cause this.
What is electric discharge as lightning?
This is what happens when electrons approach the ground, positive charges quickly flow upward, making a connection between the cloud and the ground.
What is electric discharge as lightning?
A proton and an electron will have this effect on each other.
What is attract?
Three ways that electrons transfer between objects.
What are contact, induction, or conduction?
If the amount of charge on an object remains the same, the strength of an electric field increases as the distance does this.
What is decreases?
This happens when a neutral object gains electrons.
What is getting a negative charge?
This is what the negatively charged cloud does to the Earth's surface by repelling negative charges, thus the ground becomes positive.
What is polarizes?
This type of particle allows electricity to flow.
What is an electron?
When objects made of different materials touch, electrons tend to collect on the object that hold electrons more tightly, transferring electrons by this process.
What is contact?
The strength of an electric field increases as the total amount of charge between the two objects does this.
What is increases?
This happens when objects are polarized.
What is having electrons concentrated at one end?
