- Electrons can be removed from some objects using friction , simply by rubbing one substance against another substance. There are many examples of objects becoming charged by friction, including a rubber comb through hair, and a balloon on a sweater In both these instances the electrons move from the second object to the first, causing the first object to become negatively charged and the second one positively charged. Friction between the tires on a moving car and the road cause the tires to become charged, and wind causes friction between clouds and air which causes clouds to become charged and can result in tremendous bolts of lightning. t t + his t t Morty rubs a balloon on his head and presses it to the wall. When he takes his hand away, the balloon sticks. Explain why this happens, mentioning positive/negative charge and flow of electrons.
