Miss Madsen rubbed two balloons with a piece of wool. What will happen when the balloons are brought near each other?

• The balloons will repel each other.

• The balloons will attract each other.

• The balloons will become positively (+) charged.

• The balloons will pop.

What is static electricity caused by?

• A balance of power

• A balance of positive and negative charges

• An imbalance of positive and negative charges

• An imbalance of protons and neutrons

An object will become POSITIVELY charged when it:

• loses electrons

• gains electrons

• loses protons

• gains neutrons

Two objects with LIKE static charges will

• attract each other
• even out in the end
• repel each other
• cause a spark
