Multiple Choice

Mrs. Davis 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.

Multiple Choice

What types of charges attract?

• Positive and Positive

• Positive and Neutral

• Negative and Neutral

• Positive and Negative

Multiple Choice

What is a region around a charged object where the object's electric force is exerted on other objects?

• electric field

• magnetic field

• electric charge

• negative charge

Multiple Choice

At which point is the electric field the strongest

• A
• B
• C
• D

Multiple Choice

At which point is the electric field the weakest?

• A because it is the furthest away
• A because the field lines are further apart
• C because the field lines are further apart
• C  because it is the furthest away

Multiple Choice

Electrical charge built up on the surface of an object is called _________________.

• static electricity
• current electricity
• lightning
• electrons

Multiple Choice

the charging of an object by the contact of a charged object to a neutral object (like touching a door knob)

• induction

• conduction

• friction

Multiple Choice

• conduction

• friction

• induction

Multiple Choice

Bending water with a charged balloon is an example of what type of charging (charging an object without touching)

• friction

• induction

• conduction

Multiple Choice

Which of the following is caused by static electricity?

• a stove getting hot when it is turned on
• a magnet being attracted to a refrigerator
• a lightning strike during a storm
• a light bulb coming on when a switch is turned on

Multiple Choice

Lightning occurs because ___.

• the negative charges at the bottom of clouds are attracted to the positive charges on the ground.

• the positive charges at the bottom of clouds are attracted to the negative charges on the ground.

• the positive and negative charges inside clouds are attracted to each other

• All of these reasons are correct.
