What is shown when your hair stands on end after lots of combing?
friction
induction
conduction
What would cause two balloons to repel?
one is positive and one is negative
both balloons are positive
both balloons are negative
one balloon is positive and one is neutral
Which of the following is an example of a conductor?
plastic
copper
glass
rubber
If the balloon has a negative charge, the hair must have what charge?
negative
positive
neutral
For an object to have a positive charge, it must ____.
lose electrons
gain electrons
lose protons
gain protons
_______ is when there is a buildup of charges (more of one type of charge) on an object.
static electric discharge
static electricity
current electricity
When someone's hair is charged by the person holding onto the Van de Graaf generator, you are observing ___.
friction
conduction
induction
All of the following are examples of static electric discharge EXCEPT:
lightning
getting shocked by a doorknob
the crackle sound as you pull clothes from the dryer apart
when your hair stands on end as you jump on the trampoline
Select all that describe insulators.
allow charges to flow easily
do not allow charges to flow easily
plastic
metal
surround a wire
In static electricity, charges build up on an object, but they do not flow continuously.
For an object to have a static charge it must be ferromagnetic.
What is the major difference between static electricity and current electricity?
Current electricity involves a continuous flow of elecrons; static electricity is a sudden transfer of protons
Current electricity can be deadly; static electricity is almost always safe
In current electricity, there's a single transfer of electrons; in static electricity, there's a steady flow of electrons
Current electricity involves a flow of electrons; static electricity involves a single transfer of electrons
The comb has been rubbed with a piece of wool fabric and placed next to some scraps of paper.
Some paper moves toward the comb. The movement of the paper is caused by
static electricity
mechanical energy
chemical energy
magnetic attraction
Which of the following is true?
Electric charge is transferred only when all objects have balanced charges.
Electric charge is transferred when electrons move.
Electric charge is transferred when protons move.
Electric charge is transferred when protons and neutrons change places.
Look at the set of objects to the right. We could
increase the electric force between Object A and
Object B by each of the following EXCEPT:
Pushing them farther apart.
Increasing the difference between their charges.
Moving them closer together.
Adding lots of negative charges to Object A.
Read the following statements about electric force. Which statement is NOT CORRECT?
The smaller the distance between 2 charged particles, the stronger the electric force.
The higher the charges involved, the stronger the electric force.
The greater the distance between 2 charged particles, the weaker the electric force.
The smaller the distance between 2 charged particles, the weaker the electric force.
