Electricty comes from the Greek word electron which means ______________
amber
It is the motion or flow of electrons in the form of an electric charge.
electricity
It is a fundamental property of matter that causes to be attracted toward or repelled from another charged object.
electrical charge
What is the electric charge of an electron?
-1.602x10^-19 C
True or False:
Protons and electrons can transfer to objects because they are located outside the nucleus.
False
only electrons
True or False:
Electrons can be easily removed from the atom.
True
When an electron moves, a ________ is generated.
charge
The movement of electrons makes ___________.
electricity
The gain or loss of electrons is called ________.
Ionization
The law of charges states that:
“Like charges repel each other, and unlike charges attract each other.”
The law of charges states that:
“Like charges repel each other, and unlike charges attract each other.”
Law of Conservation of charges states that:
“Charges cannot be created nor destroyed, but can be transferred from one material to another. The total charge in a system must remain constant.”
The build up of electric charges on the surface of an object.
static electricity
When the object loses its electron, it becomes ________ charged. When the object gains an electron, it becomes ________ charged.
- positively
- negatively
Gain charge by rubbing or friction.
Charging by rubbing
