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 .
