What is a conductor? What is an insulator?
A conductor is something that heat or electricity can flow through easily. An insulator is not.
100
True or False, positive charges and negative charges REPEL.
FALSE! Opposites attract! Like charges repel!
100
For a circuit to be on it needs to be ______.
Closed

If Kelvin applies the same force to an object that weighs 10 pounds to an object that weighs 40 pounds, which will need more effort?
The 40 pound object
200
What is another word for HEAT energy?
Thermal

Why are wires in a phone charger wrapped in plastic and rubber?
So we do not get shocked when plugging it in. To stop electricity from hurting us!
200
What is it called when you use heat from the earth's crust to create electricity?
Geothermal Energy

If I don't have an extra copper wire to complete my circuit, will a plastic straw work? Why or why not?
No because it is an insulator.

Which surface would friction be greatest if you are sliding a toy car across it? Ice, carpet, or glass
Carpet

If two equal forces are pulling an object in opposite directions, what will happen?
The object will not move because the forces are balanced.
