Atoms
What is static electricity?
the imbalance of positive and negative charges. In static electricity, charges build up on an object,
What is the first law of electric charge?
What is electric force?
the attraction or repulsion between electric charges
What is friction and what happens the more you rub it?
Friction is rubbing two items/objects together. The more you rub, the more electrons move.
What is grounding?
The process of removing a charge by adding or removing electrons. it involves connecting the charged object to the ground directly or via a conductor.
What are the three parts of an atom?
Proton
Electron
Neutron
What is the second law of electric charge?
Charges that are the same (+ and +) repel each other
What happens in an electric field?
extends around a charged object, the area around a charged object where the objects force is exerted
How is static electricity produced?
When grounding is done via a conductor, what is it called?
discharging
What makes up the nucleus in an atom and what are their charges?
Protons-positive
Neutrons-neutral
What is the third law of electric charge?
Both positive and negative charges attract neutral charges.
What direction does the electric field go in around a positive charge?
outward
How is an electrostatic series arranged?
What happens to the third prong on an electrical outlet?
What do they electrons do in an atom?
a. they can jump to different atoms and objects
b. they orbit the nucleus?
What direction does the electric field go in for a negative charge?
inward
What is conduction? What happens to the electrons?
The transfer of electrons from one object to another by DIRECT CONTACT. The electrons move between objects to balance the charge.
Why does grounding work?
The earth has so many electrons that no matter how many are added or taken away, it stays neutral.
By gaining or losing electrons
When are the electric fields around charged particles combined?
when they are brought near each other
What is induction? What happens to the movement of electrons?
The transfer of electrons from one object to another WITHOUT DIRECT CONTACT. The movement of electrons to one part of an object, which is caused by the electric field of another object.
What happens to the earth when a lightning rod strikes? (2 steps)
A lightning rod is attached to the highest part of a building and connected to the ground.
A thick, insulated copper wire connects the rod to a cable in the ground - sending the electricity to the ground
