 Static charge | a staionary electrical charge that is built up on the surface of a material |
| How charge is transfered | rubbed on a person's hair, a plastic ruler can attract paper scraps |
| how charge is transfered | when the ruler is rubbed, it gains electrons from the hair and becomes negatively charged, |
| proton | is positively charged |
| neutron | neutral charge |
| electron | negative charge |
| neutral | if # of electrons = # of protons |
| negative | if # of electrons is greater than number of protons |
| positive | if # of electrons is less than number of protons |
| relative rankings | those towards top of list are more likely to become postive while those towards bottom are more likely to become negative |
| electrons | are pulled from the wool to the balloon |
| electrons | balloon has more of these than usual |
| balloon | becomes negatively charged |
| wool | becomes positvely charged |
| static discharge | builds up by scuffing shoes on a carpet |
| balloon | has a negative charge when rubbed by a wool cloth |
| Don't | get back in your car when gassing up, sliding on seats can cause static electricity. |
| Don't | leave your car running while fueling, a running car is a source of sparks |
| Don't | smoke or use a lighter |
| Do | keep passengers in the car while fueling |
| do | touch metal part of the car away from the gas tank to discharge static before touching nozzle |
| negative charges | collect at the bottom of a cloud |
| negative charges | force the other negative charges in the ground down deeper, making the surface of the ground positive |
| positive charge | is pulled upward when a stream of negative charges from a cloud are a attracted by the positive ground, |
| creates a path for electrons to jump to the ground | being pulled upward when a stream of negative charges from a cloud are a attracted by the positive ground, |
| electrons | excite the air so that it emits light and heat |
| thunder | is caused when heat expands air |
