Lightning is a big…
Static discharge
Electric force is the attraction or repulsion betweeen
Charged objects
Electric charge is a property that causes electrons to either attract or…
Repel from each other.
If a neutral object loses 5 electrons, what will is overall charge be?
Positive.
charges build up in clouds because of moving….
Air
when the charges move, the total charge…
doesnt change
the strength of this force depends on how much charge the objects….
Have
Protons have a postive charge and electrons have a
Negative charge
You rub a plastic rod with a wool cloth. If the rod becomes negatively charges, what happens to the charge of the wool cloth?
It becomes positively charged.
the bottom of the cloud gets a negative charge, and the top of the cloud gets a….
positive charge
touching a charged object with your hand removes…
Explain how distance affects the strength of electric forces.
the closer, the stronger. The further, the weaker.
An atom with a nucleus and with positive charges is surrounded by..
Electrons
Two balloons are rubbed on hair and then brought close together. Will they attract or repel each other, and why?
Repel, because they will both have the same charge.
when the charge is big enough, electrons move from the cloud to the ground, creating…
Lightning
Give an example of how friction can cause static electricity.
Rubbing a balloon on hair.
Charges That are the same repel each other. Opposite charges…
when the number of positive and negative charges are equal, the atom is…
neutral
Explain why a metal doorknob is more likely to give you a static shock than a wooden door.
Metal is a conductor, allowing for rapid charge flow; wood is an insulator, so less charge flows.
pin a few words, describe what happens during static discharge.
Rapid flow of electrons
static electricity is most commonly caused by the transfer of what particle?
Electrons!
If you double the charge on an object, the electric force…..
also doubles.
describe what happens to an atoms charge when it gains or loses electrons.
Gaining electrons make its negative, losing makes it positive.
Imagine a cloud where the charge separation is twice as large as in a typical thunderstorm. How would this affect the strength of the lightning strike, and why?
The lightning strike would be stronger because a larger charge separation creates a greater potential difference, leading to a more powerful discharge
