What are the two types of electric charges?
positive (+) and negative (-) charges
What happens when a positively charged object is near a negatively charged object?
They will attract each other.
What is a material that allows electric charges to move freely?
conductor
What is the transfer of electric charge between objects not touching?
static discharge
What happens to an object that has more positive particles than negative ones?
It has a positive charge.
What are two factors that influence the strength of electric forces?
amount and distance
What is an example of an insulator?
rubber ballon
wood
plastic
What can happen when you touch a doorknob after walking on a carpet?
You may experience a static discharge.
What do we call matter that has equal positive and negative charges?
Neutral
What is the term for the push or pull that charged objects exert on one another?
electric force
How do charges behave in conductors compared to insulators?
harges can move freely in conductors but cannot move freely in insulators.
How is static electricity related to lightning?
lightening is static discharge but much more power full
If two objects have the same charge, what will happen when they are brought close together?
They will repel each other.
Name one factor that affects the strength of the electric force between two objects.
the amount of electric charge or the distance between objects
What is the main difference between conductors and insulators?
Conductors allow charge movement; insulators do not.
What sequence leads to a static discharge when touching a doorknob?
Walking on a rug, acquiring electric charges, and then touching the doorknob.
What is it called when charged objects push or pull each other?
What is electric force?
What occurs when two positively charged objects are brought close together?
They repel each other.
What happens to negative charges in a conductor when a charged rod is brought near?
They move in response to the charged rod.
What happens to your body when you walk on certain carpets?
You acquire a negative charge.
