|
static electricity
|
an imbalance of electric charge on the surface of an object
|
|
|
electric force
|
the force exerted by a charged object
|
|
|
induced charge separation
|
a shift in the position of electrons in a neutral object that occurs when a charged object is brought near it; the neutral object does not gain or loose electrons
|
|
|
charging by friction
|
electrons are transferred between two different types of neutral objects when they are rubbed together or come into contact, causing a charge of imbalance
|
|
|
charging by conduction
|
occurs when two charged objects with different amounts of charge contact each other and excess electrons from one object are transferred to the other less negatively charged object in order to produce a more even distribution of electric charge between the two objects
|
|
|
grounding
|
involves removing excess charge by transferring electrons between the object and a large neutral object like the earth
|
|
|
positively charged object grounded
|
electrons move up from ground until object is neutral
|
|
|
negatively charged object grounded
|
electrons move down from the object into the ground until the object is neutral
|
|
|
charging by induction
|
bringing a charged object near but not touching, a neutral object charges a neutral object
|
|
|
temporary induced charge
|
charging by induction without grounding
|
|
|
permanent induced charge
|
charging by induction with grounding
|
|
|
electric discharge
|
the rapid transfer of electric charge from one object to another
