5. Rub the yellow balloon on the sweater until you get all of the blue negative charges on the balloon. When you rub two things together and there is a transfer of negative charge, this charge distribution is called friction. Now, drag the balloon in between the wall and the sweater. Then release the balloon to see what happens. Explain what happened and why.

6. Now take that same balloon and drag it over to the wall. You will notice that the blue negative charges move away in the wall and then the balloon sticks to the wall. This charge distribution is called induction, because the negative charges move without any touching. Why does the balloon stick to the wall?
Type Answer HERE:
Answer 5: The balloon will accumulate the blue negative charges because of the friction between the balloon and the sweater. This friction leads to the transfer of electrons from the sweater to the balloon, resulting in an accumulation of negative charge on the balloon.
Answer 6: The balloon sticks to the wall because of the phenomenon known as induction. When the balloon is brought close to the wall, the negative charges on the wall are repelled by the negative charges on the balloon. As a result, the negative charges on the wall move away from the balloon, leaving a positively charged region on the wall. The positive charges on the wall then attract the negative charges on the balloon, causing it to stick to the wall.
