-Any net charge on a solid object, whether it is positive or negative, results from the transfer of electrons between this object and another object

- Different materials hold on to their electrons with different strengths

－Static electricity can be a nuisance or even a danger. The energy that makes your hair to stand on end can also damage electronics and cause explosions.

-static electricity can be a nuisance or even a danger, as in the case of static cling or static shock, in other cases it can be quite useful. ]]> 2016-10-13 02:04:39 UTC https://padlet.com/yichuanw/telw4zcs2qm4/wish/130313897 yichuanw https://padlet.com/yichuanw/telw4zcs2qm4/wish/130316243 2016-10-13 02:25:45 UTC https://padlet.com/yichuanw/telw4zcs2qm4/wish/130316243 yichuanw https://padlet.com/yichuanw/telw4zcs2qm4/wish/130316980 2016-10-13 02:33:30 UTC https://padlet.com/yichuanw/telw4zcs2qm4/wish/130316980 Static electricity  yichuanw https://padlet.com/yichuanw/telw4zcs2qm4/wish/130655547 When two objects are rubbed together to create static electricity, one object gives up electrons and becomes more positively charged while the other material collects electrons and becomes more negatively charged. This is because one material has weakly bound electrons, and the other has many vacancies in its outer electron shells, so electrons can move from the former to the latter creating a charge imbalance after the materials are separated. ]]> 2016-10-14 06:58:37 UTC https://padlet.com/yichuanw/telw4zcs2qm4/wish/130655547 yichuanw https://padlet.com/yichuanw/telw4zcs2qm4/wish/130667589 2016-10-14 08:18:38 UTC https://padlet.com/yichuanw/telw4zcs2qm4/wish/130667589 yichuanw https://padlet.com/yichuanw/telw4zcs2qm4/wish/130667613 2016-10-14 08:18:47 UTC https://padlet.com/yichuanw/telw4zcs2qm4/wish/130667613 yichuanw https://padlet.com/yichuanw/telw4zcs2qm4/wish/130668172 2016-10-14 08:22:11 UTC https://padlet.com/yichuanw/telw4zcs2qm4/wish/130668172
