Intro to Electrostatics

All objects start outneutral

Neutral means equal numbersof t & - charges

You can charge an objectby rubbing twoobjects together

Negative charges canmove from one objectto another

The object that losesnegatives becomes positive

Oppositely charged objectsattract each other

Two like chargesrepel each other

Develops a successful theoryto explain how object get

charge

Names the charges t & -

Used to predict charge+ when two objects are

rubbed together .

things that are higher upwill lose electrons to become

negative-

As distance gets smaller,

the force gets larger .
