How is the contact different between a balloon and sweater and a balloon and the wall?

Balloons may stick to a knit sweater, but normally the electromagnetic force will oppose it. However, once a balloon is rubbed on a sweater, it can stick to a wall (or other surface) by creating an electrostatic (magnetic) field with the stationary wall.

What is the hypothesis for static electricity?
My hypothesis for my experiment was that rubbing the balloon on the wool sweater will make the balloon stay on the desk the longest. I believe this because the sweater was furry. I also predicted that there would not be a different in the amount of time the balloon stayed on the desk at different times of day.
Why does a balloon stick to the wall when you rub it on a sweater?
static electricity
You watch your friend rub a balloon on their sweater and then stick it to the wall. To investigate, you set up an experiment to test what happens with other objects. What's the test variable in your experiment?
Answer: When you put the balloon on the wall after you rubbed it on the sweater. the balloon would either stick to the wall or repel from the wall depending on what kind of electrons there are on the sweater
Why do a balloon get stuck to the wall when it rubs against your hair or a wool sweater?
because of charge
Can electrons move or cannot move from one object to another when rubbed together?
Probably because they can. Before we had transistors we had vacuum tubes. In them electrons move between objects. They also move electrons between objects in particle accelerators. If your community has a cancer center in its hospital, you might ask them if you could have a tour of the radiation therapy department. The "linacs" used to treat cancer accelerate electrons.

How is a cardigan sweater different from a regular sweater?
A cardigan sweater does not have a hood and it has buttons in the front as a closure. Regular sweaters can have buttons or zippers and can also have a hood.
How is yarn in a sweater and wool from a sheep different?
because the yarn in the sweater is cleaned and died and the wool on the sheep is not
If two balloons are rubbed on a wool sweater they should stick to each other?
The balloon has a greater affinity for electrons so it obtains a negative charge after being rubbed against the sweater. The balloon, containing a highly negative charge, sticks to the wall because it is attracted to the positive charges in the wall (opposites attract). After a while, the balloon's extra electrons move to the wall and both objects become neutrally charged. Lacking any significant attraction, the balloon will fall off the wall.
What is the difference between sweater weather and jacket weather?
A sweater is for when the weather is around 45 degrees. A jacket is for when the weather is around 20 degrees.
Are electrostatic forces large or small?
Compared to what ? Here's something to think about: There are some bits of tissue lying on the table on a dry day. You rub a balloon against your sweater a few times, and then you pass the balloon low over the bits of tissue. In response to the electrostatic force of the charged balloon, the bits jump off the table and up to stick to the balloon ... even though the gravity of the whole Earth is pulling them down.
