Presentation Transcript

  1. Static Charges Notes

  2. Magnetism Force of attraction/repulsion Unlike = attract Like = repel http://www.bbc.co.uk/schools/ks3bitesize/science/images/sci_dia_74.gif

  3. Charged Particles Found in atom Proton (positive) Electron (negative) Unlike charges = attract Like charges = repel Ben Franklin gave names positive and negative to the charges! http://www.geocities.com/CapeCanaveral/Hall/1410/charges.gif

  4. Similarities/Differences Same two ends (pos/neg; north/south), field around them, like repel, opposite attract Different Magnetic poles = pairs Electric charges = alone

  5. Electric Field Where electric force (attract/repel) around charged particle felt Lines = direction and strength Closer together lines… stronger the electric field http://www.rwc.uc.edu/koehler/biophys.2ed/images/fields2.gif

  6. Field Lines http://buphy.bu.edu/~duffy/PY106/2e.GIF http://www.school-for-champions.com/science/electrical_charges.htm

  7. Neutral? Protons = electrons

  8. Static Electricity Static = stationary Temporary partial charge Charges build up – do not continue to flow http://www.esdsystems.com/images/carpet.gif

  9. Transfer Conservation of Charges: Not created or destroyed; Transferred Electrons flow Lose electrons  positive Gain electrons  negative Friction – rubbing of uncharged objects Conduction – touching of a charged object to another object Induction – no touching, caused by electric field of charged object

  10. Visibility Charges not seen Detected by electroscope Static Discharge – transfer until equal charges Can cause a spark (like lightning)! http://www.science.uwaterloo.ca/~cchieh/cact/nuctek/interact.html http://weathereye.kgan.com/cadet/lightning/electricity.html
