AP PhysicsWednesday 14.02.25 Standards: 2b2 solve equilibrium problems. Objective: SWBAT will be able to score 3 or higher on their test. Agenda • Warm Up • Test 5m 70° 10kg Homework NA

  4. Warm Up Write down what you know about electric charge, conductors and insulators and write down any questions you may have about them. AP PhysicsThursday 14.02.19Standards: 1a1 Students should understand the concept of electric charge, so they can: Describe the types of charge and describe polarization & inductionObjective: SWBAT describe the different ways in which charges interact with each other and how they will arrange themselves in conducting surfaces Agenda • Warm Up • Review Test • Explore electric charges through Phet https://phet.colorado.edu/en/contributions/view/3044 • Read Electric Charging • Discuss Electric Charging Homework E#1 Electric Charge

  5. AP PhysicsFriday 14.02.20 Warm Up Draw a diagram that illustrates the process of conduction. Standards: 1a1 Students should understand the concept of electric charge, so they can: Describe the types of charge and describe polarization & inductionObjective: SWBAT describe the different ways in which charges interact with each other and how they will arrange themselves in conducting surfaces Agenda • Warm Up • Conduction, Polarization, Induction Notes • Guided Practice Homework E#1 Electric Charge

  6. For each of the following, draw the charge distribution and specify whether conduction, induction, and/or polarization is occurring. Guided Practice A The rod is moved close to the conducting sphere but never touches B The rod touches the conducting sphere on the right C The two neutral conducting sphere’s touch. A negatively charged conducting rod is brought close, then sphere A and B are separated and the rod is taken away. B A D. Draw a neutral insulating sphere with 5 positive and 5 negative charges.

  7. E#1 Electric Charge & Conducting Sphere’s Practice 1 (66.) Two initially uncharged conductors, 1 and 2, are mounted on insulating stands and are in contact, as shown above. A negatively charged rod is brought near but does not touch them. With the rod held in place, conductor 2 is moved to the right by pushing its stand, so that the conductors are separated. Which of the following is now true of conductor 2? (A) It is uncharged. (B) It is positively charged. (C) It is negatively charged. (D) It is charged, but its sign cannot be predicted. a. A neutral rod is places on a positively charged conducting sphere. What will be the charge of the conducting sphere? Draw the resulting configuration. c. How much charge do 10 electrons have? d. How much charge do 25 protons have? b. Three neutral conducting spheres touch. Draw the charge distributions after a positively charged rod is placed near the left sphere and a negatively charged rod is placed near the right sphere. 2(110.) A charged rod is placed between two insulated conducting spheres as shown. The spheres have no net charge. Region II has the same polarity as Region (A) I only (B) III only (C) IV only (D) I & III only (E) I & IV only
