1. Electric Charge & Force Static Electricity

2. Electric Charge An electrical property of matter that creates a force between objects Ex. When you get shocked touching a door knob Charges can be positive or negative Charges are a result of the gain or loss of electrons

3. Like Charges vs Opposite Charges Like Charges  REPEL Opposite Charges  ATTRACT Ex. Rubbing a balloon on your hair  Hair is positive balloon is negative

4. Conductors & Insulators Conductors  Allow electric charges to flow freely Insulators  Do not transfer charges Can you think of an example of each?

5. Friction How can we transfer electrons?  Rub items together  One object gains electrons and the other loses electrons  This is charging by friction

6. Contact Charging by Contact  A neutral object can be charged by “touching” it with a charged object

7. Induction Neutral Objects are attracted to charged particles In the neutral object there is a rearrangement of electrons

8. Electric Force The force of attraction or repulsion between objects due to charge It is not necessary to touch in order for there to be a force

9. Electrical Field A charged particle produces an electrical field around it If a second particle is in the electrical field it will feel a force from the first particle Force field lines show the direction of the forces
