Click on the balloon and drag it over and rub the balloon against the wall.
Describe what, if anything, happens to the balloon/wall.
Pull the balloon slightly away from the wall and release it, does anything happen?
Now drag the balloon over the sweater and rub it against the whole sweater.
Describe what, if anything, happens to the balloon/sweater.
Count the number of positive and negative charges on each object in the simulation and determine the overall charge of each object.
The totals for the sweater and yellow balloon will be the same as in the first table in 1a.
Overall Charge = negative charges + positive charges
Object | Neg Charges | Pos Charges | Overall Charge |
|---|---|---|---|
Sweater | |||
Green Balloon | |||
Yellow Balloon |
Overall Charge = negative charges + positive charges
Object | Neg Charges | Pos Charges | Overall Charge |
|---|---|---|---|
Sweater | |||
Green Balloon | |||
Yellow Balloon |
Drag the green balloon over to the yellow balloon.
What effect, if any, does it have on the yellow balloon? Why or why not?
Now drag the yellow balloon and rub it against the left-hand side of the sweater. Determine the new charges.
Object | Neg Charges | Pos Charges | Overall Charge |
|---|---|---|---|
Sweater | |||
Green Balloon | |||
Yellow Balloon |
Pull the green balloon off the sweater and put it all the way across the room. Quickly grab the yellow balloon and bring it near the green balloon.
What happens when the balloons are brought together?
Why does this happen?
Try to find a way to get the 2 balloons to stick to each other away from the sweater.
What would you need to do in order to get the balloons to stick together?
After completing this activity is it possible to do that? Why or why not?
When an object becomes charged which charge is transferred between the objects?
How does an object become positively charged?
How does an object become negatively charged?
In order to repel each other two objects must have
In order to attract each other two objects must have
When the balloon was brought near the wall, the wall technically stayed neutral, but the balloon was still attracted to the wall. How can this be explained?
Count the number of positive and negative charges on each object in the simulation and determine the overall charge of each object.
Overall Charge = positive charges + negative charges
Example: +14 + -12 = +2
Object | Neg Charges | Pos Charges | Overall Charge |
|---|---|---|---|
Sweater | |||
Balloon | |||
Wall |
Count the number of positive and negative charges on each object in the simulation and determine the overall charge of each object.
Overall Charge = positive charges + negative charges
Example: +14 + -12 = +2
Object | Neg Charges | Pos Charges | Overall Charge |
|---|---|---|---|
Sweater | |||
Balloon | |||
Wall |
Pull the balloon back toward the middle of the simulation and let it go.
Describe what happens.
How can you explain this occurrence?
Drag the balloon over to the wall. Bring the balloon near the wall.
Describe what happens within the wall.
Why do you think this happens?
Hold the balloon just away (barely off of it) from the wall and release it.
Describe what happens.
Why do you think this happens?
Hold the balloon a little further from the wall and release it, keep repeating this moving the balloon a little bit further from the wall each time until the balloon stops being attracted to the wall.
What eventually happened?
Is the balloon more attracted to the sweater or the wall? Why?
