2Electric Charge All objects are made up of atoms Atoms consist of 3 partsProtonsElectronsNeutrons
3Electric ChargeBen Franklin described each part of the atom as having an electric chargeProtons have a positive charge (+)Electrons have a negative charge (-)Neutrons have a neutral charge (neither + nor - )
4Repel & AttractCharges that are the same repel one another or push each other awayCharges that are opposite attract one another or pull each other togetherThe same rules apply to magnets
5Electric FieldsThe force of electric charges can be felt for a distanceAn Electric Field is the area of force surrounding a chargeCharged particles placed in an electric field will either repel or attract.
7Static ElectricityObjects become charged by gaining or losing electronsProtons are bound to the atom tightlyStatic Electricity is when charges build up on an objectStatic means fixed or unmovingStatic charges do not flow
8What to Work On DUE: Friday, 3/16 Section 2.1 Review Questions Page 53, Questions 1-4 and 6DUE: Friday, 3/16
9Atoms are made of 3 parts. Which of these is NOT one of them? 1Proton2Electron3Positive / Negative4Neutron
10Put the following parts in the correct order: Negative, Neutral, Positive. 1Proton, Neutron, Electron2Electron, Proton, Neutron3Neutron, Electron, Proton4Electron, Neutron, Proton
11Which of these statements is TRUE? 1Particles with the same charge repel2Particles with the same charge attract3Particles with opposite charges repel
12Transferring ChargeCharges can be moved from one object to another in 3 different ways:Friction moves electrons by rubbing two objects togetherConduction transfers electrons from a charged object through touchInduction is when electrons move from an object because of electric fields.
13Static DischargeWhen a negatively charged object and a positively charged object are brought together, electrons move until both have the same chargeStatic Discharge: Two charged objects will create a balanced charge.
