Conductors and Insulators
Why do mittens keep your hands warm in the winter?
They are insulators.
What is energy?
The ability to do work
The stored energy in a battery is _______ into electricity.
Transformed
Objects with opposite charges will ______
Attract
Give an example of an insulator and a conductor.
Conductors- metal, copper, salt water...
Insulators- Rubber, oil, plastic...
How is kinetic energy transferred?
When one object hits another
What type of charges are released in a battery?
Negative charges
Repel
What is the difference between a conductor and an insulator?
A conductor allows electricity to flow through it easily and an insulator does not.
What type of energy is transferred when one domino hits another domino?
Kinetic to kinetic
What type of energy is stored inside a battery?
Chemical energy
What kind of charge do most objects have?
Neutral charge
Why are metals useful for making electrical wiring?
A battery converts what type of energy to another?
Chemical to electrical
They are attracted to the positive side of the battery. (Opposites attract!)
A sweater and a balloon are both neutrally charged. What makes them neutrally charged?
They both have an equal amount of positive and negative charges.
Why is electrical wiring covered with a layer of plastic?
To prevent electrical shock
On a roller coaster, where is the maximum potential and maximum kinetic energy?
Potential: At the top of a big hill
Kinetic: At the bottom of a big hill
What gives the negative charges the pathway to flow?
The wires of the circuit (Conductors)
What will happen to two neutrally charged objects?
They will neither attract or repel.
