What is electric charge?

• A propert of the particles of atoms involving electron charge

• The movement of electrons

• Electric charge doesnt exist

• Part of the atomic theory

Only _________ move

An object with more electrons than protons will be __________ charged

If there is an equal number of electrons and protons the object is _________ charged

Two objects with ____ charges will repel each other

two objects with unlike charges will _______ each other

What is the law of electric charges?

• Objects in the mirror are closer than they appear

• Dry air is an insulator

• static electricity is the movement of electrons in a controlled way

• Two objects with like charges will repel each other, two objects with unlike charges will attract each other

True or false: In order for an object to become electrically charged it must gain or lose electrons

• True

• False

• no

• Neither

What is static electricity?

• The movement of electrons in a controlled way

• When the charge remains where the rubbing action occurs on each side of the charged objects

• when the air is moist and the water molecules transfer charges

• When an object is rubbed against another rapidly and both become charged the same

Why is static electricity worse in the winter? (basic answer)
