Chapter 16 Internet links for Electric fields and forces. Follow the path through these web sites. This order is the same as the order of questions on your worksheet that you need to complete for a lab grade. Conductivity Please follow and complete the handout that goes with this activity. Non-obvious controls: You can type in a value for the battery voltage or use the arrows to change it. Insights into thinking: The voltage does not create the electrons in a circuit. This program helps you see that electrons are always in the circuit and the voltage just makes them move. The energy diagram represents a graph, not a physical object. Follow the directions on the conductivity handout while and completing the handout. Charge transfer with rubbing balloon and resulting forces on balloon or wall ANSWER THESE QUESTIONS ON YOUR HANDOUT 1) What do you think happened to make the balloon negatively charged? 2) After rubbing them together, how does the charge on the balloon compare to the charge on the sweater? 3) Why does the balloon want to to the sweater in some cases and stick to the “stick” wall in others? Explain the differences. 4) What experiences have you had that are similar, and could be explained by electrostatic force? John Travoltage See how static electricity builds up as John rubs his foot on the carpet Experiment with how much charge is needed before being shocked depending on the distance hand is from the doorknob. Answer the following questions on the handout. Explain what happens when John rubs his foot on the carpet. What do the blue spheres represent? What did you notice about when the shock occurs? How does it relate to the amount of charge and the position of John’s arm? What happens when John touches the doorknob after his foot has been rubbed on the carpet multiple times? Conductor vs insulator Read this and answer the 5 questions at the bottom on your handout. Section 16-2 Coulomb’s law
