Lesson 1 Electric Charge Flashcards
Comes from the Greek word
electron which means “amber”
Electricity/Electrical Energy
Electron MEANS,
Amber
It is a fossilized resin material
used in jewelry
Amber
is the motion or flow of electrons in the
form of an electric charge
Electricity
Is a fundamental property of matter that
causes to be attracted toward or
repelled from another charged object.
Electrical Charge
Only the Electrons
can transfer to
objects because
they are located
outside the nucleus.
Free Electrons
The gain or loss of electrons is called
Ionization
Like charges repel each other, and
unlike charges attract each other
Law of Charges
Who proposed the law of charges and Law of Conservation of Charge
Benjamin Franklin
Charges cannot be
created nor destroyed,
but can be transferred
from one material to
another. The total charge
in a system must remain
constant.
Law of Conservation of Energy
Is the build up of electric charges on the
surface of an object
Static Electricity
When the object loses its electron,
it becomes -_______________________, When the object gains an electron, it becomes _______________________
Positively Charged, Negatively Charged
Gain charge by rubbing or friction
Charging by Rubbing
Is an arrangement of materials / substances
according to their ability to gain or lose electrons.
Triboelectric Series
Charge is created in a nearby object, without direct
contact
Charging by Induction
