Ms. Piskor rubbed a balloon on an old sweater and the balloon gathered more electrons.

Where did the electrons come from?

• The electrons went from the balloon to the sweater

• The protons left the balloon and went to the sweater, making the balloon falsely appear more negative

• The electrons left from the sweater to the balloon due to the friction

• Trick question: protons and electrons never move

What is the unit in measuring the amount of charge an object has?

• Coulomb (C)

• Electrostatic Force (F_e)

• Electrostatic constant (k)

• Electrostatic distance (E_d)
