Baseline Test: Static Electricity

Static electricity can be defined as:

• The movement of charges on the surface of an object.

• The movement of neutrons on the surface of an object.

• The movement of protons on the surface of an object.

• The accumulation of charges on the surface of an object.

A positive charge is defined as:

• An excess of electrons.

• A deficiency of electrons.

• An excess of protons.

• A deficiency of protons.

The particle responsible for the charges associated with static electricity is:

• A

• B

• C

• D

A negative charge is defined as:

• An excess of electrons.

• A deficiency of electrons.

• An excess of protons.

• A deficiency of protons.

Lightning is a massive static discharge of excess electrons.

• TRUE

• FALSE

Why do these objects NOT attract each other?

• Both are positively charged.

• Both are negatively charged.

• Both are neutrally charged.

• Not enough information to answer the question.

If the cats fur is positively charged, then the polystyrene pieces are:

• Positively charged.

• Negatively charged.

• Neutrally charged.

• Not enough information to answer the question.

What happens to these two spheres?

• They attract each other.

• They repel each other.

• They do not move.

• Not enough information to answer the question.

What happens to these two spheres?

• They attract each other.

• They repel each other.

• They do not move.

• Not enough information to answer the question.

The girls hair stands up like this because:

• The hairs all have the opposite charge therefore repel each other.

• The hairs all have the same charge therefore repel each other.

• The hairs all have no charge at all.
