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 1.Protons 2.Electrons 3.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

8 What to Work On Section 2.1 Review Questions Page 53, Questions 1-4 and 6 DUE: DUE: Friday, 3/16

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

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

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

12 Transferring Charge Charges can be moved from one object to another in 3 different ways: 1.Friction 1.Friction moves electrons by rubbing two objects together 2.Conduction 2.Conduction transfers electrons from a charged object through touch 3.Induction 3.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: Static Discharge: Two charged objects will create a balanced charge.
