PHYSICAL SCIENCE A GUIDED NOTES SUMMARY FOR MODULE : ELECTRICITY AND MAGNETISMGuided Notes Summary -Electricity and MagnetismGuided Notes: Module 6: These questions are essential questions, the answers to which summarize the key concepts from each lesson. Read the question, write the answer in your own words; use illustrations and examples as appropriate to enhance your understanding. You will be required to submit the completed document to your DBA. Essential QuestionsNotes9.01 METHODS OF CHARGINGWhat makes an atom electrically neutral? How do we make an object positively or negatively charged?Explain how a ruler rubbed with a glass rod gets charged. Give examples from everyday life for how friction creates chargesExplain how charges can exert forces on each other. Property FrictionConductionInduction Objects in contact or notMechanism of charging(use diagrams)Nature of charge on the
