static and shtuff Flashcards
what is lightning
negative charge moving towards a positive charge
what are the stages of lightning
electrons and protons rearrange in the cloud due to too many electrons and the attraction towards the ground (positive charge). the electrons move towards the clouds and are released from the cloud in a strike of lightning
conductors
materials that allow electrons to move easily. copper and metals
insulators
materials that do not allow electrons to move easily. wood and rubber
semiconductors
materials that can sometimes be insulator or conductor. silicon
friction
rubbing two objects together to cause a transfer of electrons.
conduction
touching two object together to transfer electrons
induction
charged object comes close to another object rearranging electrons
grounding
connecting a charged object to the earths surface, creating a path for charges to travel to and from the earth
protons
positive atomic particles. inside the nucleus
electrons
negatively charged atomic particles. outside the nucleus
neutrons
an atom containing equal amounts of positive and negative charge. inside the nucleus
neutral atom
not net charge, positive and negative charges are balanced
cation
positive net charge
anion
negative net charge
