ElectricityProtons-✔ ✅Positive electric charge
Electrons-✔✅Negative electric charge
Neutrons-✔✅No electrical charge
electrically neutral atom-✔✅number of protons = number of electrons
(neither attract nor repel)
static charge-✔ ✅an unbalanced negative or positive electric charge on an
object
✅
Electic force-✔ A force between charged objects which can still happen
even when they are not touching
✅
Coulomb's Law-✔ Electric force and electric charge are directly related
and electric force and distance are inversely related
✅
electric insulator-✔ A material in which electric charges cannot easily
move (higher the resistance the better it is)
✅
electric conductor-✔ A material in which electric charges can easily
move (lower the resistance the better it is)
✅
Conduction-✔ the transfer of electric charge by a simple touch when
electric charges flow from one conductor to another
✅
Induction-✔ the transfer of electric charge by scrambling electrons in
conducting materials. A charged object scrambles the electrons in two
conducting materials it is brought near by repelling the electrons in the
conductors so that more electrons are on the far object. When the
conductors are separated, the charges are trapped and can't return to
where they were before
