because …..

A material through which an electron does not easily flow.

Two objects will attract each other

when…

One example of a good conductor is …

An electric field gets stronger as you …

An equal number of protons and

electrons

What is an insulator?

When they have opposite charges?

An example of a good conductor is …

The steady flow of electrons through a conductor is ….

When the resistance in an electric circuit increases, the current flowing in

the circuit …..

A circuit that has two or more paths

for electrons to follow is a …..

A continuously flowing closed loop is a …

What is copper?

What is electric current?

What is decreases?

What is parallel circuit?

What is a circuit?

A circuit that has only one path for the current to follow.

The build up of static charge on a object

How much electric energy is in an object

Which of the following is a device designed to open an overloaded circuit and prevent overheating?

a.Circuit breaker

b.Conductor

c.Resistor

d.insulator

The rate at which an electrical device converts energy from one form to

another is called….

What is a series circuit?

What is static charge?

What is voltage?

What is a circuit breaker?

What is electrical power?

Heat from the sun moves through space by the

process of ….?

An example of a longitudinal wave is a _________ wave.

Classrooms with carpet are quieter than classrooms with tile because the sound waves are __________.

Gravity on the moon is about 1/6th the gravity felt on earth,

this is because…?

The distance from the rest line to the crest is called ...?

What is radiation?

What is a sound wave?

What is absorbed?

The moon is much less massive that the earth.

What is the amplitude?

Electric companies usually sell electrical energy in units of…

a.Watts

b.Amperes

c.Volts

d.Kilowatt-hours

These kinds of circuits are less expensive to

make and have one path or branch

Homes are usually wired with these kinds of circuits and

why?

Can objects be charged by moving protons from one object

to another?

Explain how grounding can offer protection

from electric disharges.

What is kilo-watt hours?

What is a series circuit?

Parallel circuits because if one circuit goes out the rest of the

circuits will keep working

No, proton are held tightly with neutrons in the nucleus of an atom.

Grounding causes excess charge to drain into the earth which can absorb the excess

charge.
