1) Take a moment to look at the items the simulator window is displaying (balloon, sweater, wall, charges, etc.) 2) a) Sketch the charges on the sweater AND the balloon in the BEFORE box to the left. b) Then, rub the balloon on the sweater and watch what happens! Draw the charges on both items in the AFTER box on the right. Sweater and balloon BEFORE Sweater and balloon AFTER Overall charge of sweater: charge of sweater: Overall eharge of balloon: Overall Overall eharge of balloon: 3) Remove the balloon from the sweater and attempt to place it directly in between the sweater and the wall. Do this several times and observe what happens. Explain why the balloon is attracted to one item more than the other. 4) Bring the balloon all the way to the wall so that they are touching and release it. Is the balloon is able to stick to the wall? Do you think it is as strong an attraction as to the sweater? Explain why or why not.
