  1. Tuesday, April 10thEven Day • Lesson Steps: Introduce E&M with Video; Explorer learning registration; Ready, Set, Gizmo! • Do Now: What do you know about electrons, protons and current? • Homework: None – yet…

  2. Wednesday, April 11thOdd Day • Lesson Steps: • Introduce the big picture • LIBRARY • E&M Notes • Assignment 1 (Vocab, Bookwork and Questions) • Explorer learning registration • Gizmo! All of this will be due on 4/17, so pace yourself accordingly! • Do Now: Get a copy of “Pith Ball Lab” and attach it to your notebook. • Homework: None – yet…

  3. Expect a quiz!A quick word… WARNING! May cause crying… Since you are now responsible for vocab terms and questions to go along with the notes, you can expect a notebook quiz at the end of each assignment. I WILL go over correct definitions/answers with you in class before the quiz. However, it is YOUR job, not mine, to make sure that you have the correct definition. Your classwork grades will be dependent on completeness, citations and effort. NOT CORRECTNESS. You can expect a notebook quiz before we begin chapters 19 and 20. That means April 19th and 20th.

  4. Thursday, April 12thEven Day • Lesson Steps: • Introduce the big picture • LIBRARY • E&M Notes • Assignment 1 (Vocab, Bookwork and Questions) • Explorer learning registration • Gizmo! All of this will be due on 4/18, so pace yourself accordingly! • Do Now: Get a copy of “Pith Ball Lab” and attach it to your notebook. • Homework: None – yet…

  6. Assignment Set #1: Chapters 17 & 18Due by E.O.C. Tuesday, April 17th/Wednesday, April 18th All of this must be done in your own words! • Answer all “Questions” in your notebook. Cite where you found your answers if you looked ‘em up (but I would recommend your textbook here…). • Define any term that is underlined and italicizedin your notebook. You may use your textbook, a dictionary or the internet. CITE YOUR SOURCE, even if it’s yourself! • Bookwork! (in your notebook) Weird… it all goes in my notebook…!

  7. Unit 6: Electricity Chapters 17 - 20

  8. Chapter 17:Electric Forces and Fields • Objectives: • Understand basic properties of electric charge • Differentiate between conductors and insulators and the 3 methods of charging • Coulomb’s Law • Electric Field strength

  9. Basic properties of electric charge: • Two types of charge carriers: protons (positive) and electrons (negative). Their charge is conservedand quantized. • Question 1: What is the charge/mass of a proton? An electron? Include units! • Question 2: Who figured this out? How? • There are two types of materials: conductorsand insulators. • Three ways to charge an object: contact, induction and polarization. • Question 3: What methods of charging work for what materials?

  10. Electric force and Coulomb’s Law: • Coulomb’s Law describes the FORCE generated by two electric charges separated by a distance: • Question 4:What do each of these variables stand for? What are the units? • Question 5: Write a word problem for your new equation! (Check out the book if you need some examples.) • Electric Force is a field force, much like gravity. • Question 6:Which field force is stronger, gravity or electric force? What do they have in common?

  11. The Electric Field • The electric field is represented with the following equation which supposes that a small, positive test charge (q0) is brought in to test the strength of the field made by q. • Question 7: What is the equation for the electric field strength from a point charge? • Electric field linesalways point from a positive charge to the negative charge. • Question 8: Draw the electric field lines for a: • +3 C charge and a -6 C charge at a distance, r. • +3 C charge and a +6 C charge at a distance, r.

  12. One last thing… • Conductors in electrostatic equilibrium follow four main rules: • The E-field is zero inside the conductor • Any excess charge is on the surface • The E-field just outside the conductor is perpendicular to the surface • If the surface is irregular, the majority of the charge will be at the sharp points. • Question 9: Draw this for both a sphere and an irregular shape of your choice.

  13. Chapter 18:Electrical energy and capacitance • Objectives: • Define and compute electrical potential energy for various charge distributions • Distinguish between electrical potential energy, electric potential and potential difference • Calculate the capacitance of various devices and how much energy is stored in a capacitor

  14. Electrical Potential Energy • There are two equations for electric potential energy: • In a uniform electric field: • For a pair of charges: • Question 10:What do each of the variables stand for? What are their units?

  15. What’s the difference? (between all the potential, of course!) • It is important to understand the difference between electric potentialand potential difference. • Question 11: What is this difference? (Explain in your own words!) • There are three equations for potential difference. • General: • In a uniform electric field: - E∆d • Between a point charge and a point charge at infinity: • Question 12: What do each of the terms mean? What are their units?

  16. Capacitance • Capacitance is used in a lot of electric circuits, from cars to radios. The most general equation that represents it is: • In some cases, capacitance takes place in a vacuum. That is defined as: • Question 13: What is capacitance dependent on? • Question 14: How do you use a capacitor in a circuit? • You can relate the electric potential of a circuit to the capacitance though: • Question 15: What do each of the variables in these 3 equations stand for? What are their units?
