1. Three Methods of Electrostatic Charging

2. FRICTION Friction between the objects allows electrons to move from one object to the other

3. + - Objects charged by friction - - - - - -- - - - - + + + + + + + + + + +

4. CONTACT Touching a charged object to an uncharged object transfers some of the charge + + + + + + + + +

5. + + ++ + Objects charged by contact + + + + + + + + + + +

6. INDUCTION A charged object is brought close to an uncharged object + + + + + + + +

7. + This induces the electrons to move in the uncharged object. - Polarization + + + + + + + + + + + + - - - -

8. If contact is then provided to the ground electrons will flow onto or off of the object. - - - - - Grounding + - + + + + + + + + + + + + - - - -

9. This produces an object that has the opposite charge of the original charge. Objects charged by induction + - + + + + + + + - - - -

10. Conservation of Charge Charges are neither created nor destroyed but are moved from place to place and object to object.
