Triboelectric Series

Which pair of materials is more likely to give up electrons when the materials are rubbed together?

• Wood vs. human hair

• Plastic wrap vs. steel

• Cotton vs. silk

• Rubber vs. glass

What happens to the position of the positive charges when objects are rubbed together?

• They move to the object losing electrons

• They move to the object gaining electrons

• They are created

• They do not change

What happens when two objects made out of different materials are rubbed together?

• They both become positively charged

• They exchange electrons and one becomes negatively charged while the other becomes positively charged

• They both become negatively charged

• Nothing happens

These insulators typically lose their electrons when rubbed with anything else.

• Metersticks

• Electrophorus

• Plastic Tubes

• Rabbits' Fur

What is allowing the balloon to be attracted to the neutral wall in this picture?

• The wall is polarized in the presence of the balloon

• The balloons positives attract the wall

• The wall feels an attraction of two like charges

• The triboelectric series says that balloons and walls will get opposite charges.
