1. Electric Charge & Static Electricity
Electricity & Magnetism Chapter 2.1
Pages 46-53

2. Electric Charge All objects are made up of atoms
Atoms consist of 3 parts
Protons
Electrons
Neutrons

3. Electric Charge
Ben Franklin described each part of the atom as having an electric charge
Protons have a positive charge (+)
Electrons have a negative charge (-)
Neutrons have a neutral charge (neither + nor - )

4. Repel & Attract
Charges that are the same repel one another or push each other away
Charges that are opposite attract one another or pull each other together
The same rules apply to magnets

5. Electric Fields
The force of electric charges can be felt for a distance
An Electric Field is the area of force surrounding a charge
Charged particles placed in an electric field will either repel or attract.

6. Electric Fields

7. Static Electricity
Objects become charged by gaining or losing electrons
Protons are bound to the atom tightly
Static Electricity is when charges build up on an object
Static means fixed or unmoving
Static charges do not flow

DUE: Friday, 3/16

9. Atoms are made of 3 parts. Which of these is NOT one of them?1
Proton 2
Electron 3
Positive / Negative 4
Neutron

10. Put the following parts in the correct order: Negative, Neutral, Positive.1
Proton, Neutron, Electron 2
Electron, Proton, Neutron 3
Neutron, Electron, Proton 4
Electron, Neutron, Proton

11. Which of these statements is TRUE?1
Particles with the same charge repel 2
Particles with the same charge attract 3
Particles with opposite charges repel

12. Transferring Charge
Charges can be moved from one object to another in 3 different ways:
Friction moves electrons by rubbing two objects together
Conduction transfers electrons from a charged object through touch
Induction is when electrons move from an object because of electric fields.

13. Static Discharge
When a negatively charged object and a positively charged object are brought together, electrons move until both have the same charge
Static Discharge: Two charged objects will create a balanced charge.
