Physics 200 2015-2016 Chapter 18 – Electric Charge and Electric Fields Class # Date 12 02-08-16 B 13 02-09-16 A 14 02-10-16 B 15 02-11-16 A Topics & Activities Electricity & Magnetism 18.1. Static Electricity and Charge: Conservation of Charge Define electric charge, and describe how the two types of charge interact. Describe three common situations that generate static electricity. State the law of conservation of charge. Van de Graaff Generator 18.2. Conductors and Insulators Define conductor and insulator, explain the difference, and give examples of each. Describe three methods for charging an object. Explain what happens to an electric force as you move farther from the source. Define polarization. PhET – Balloons and Static Electricity PhET – John Travoltage 18.3. Coulomb’s Law State Coulomb’s law in terms of how the electrostatic force changes with the distance between two objects. Calculate the electrostatic force between two charged point forces, such as electrons or protons. Compare the electrostatic force to the gravitational attraction for a proton and an electron; for a human and the Earth.

Calculate the force exerted on a test charge Assignment Due 16 02-12-16 B 17 02-15-16 A 18 19 02-16-16 B 02-17-16 A by an electric field. Explain the relationship between electrical force (F) on a test charge and electrical field strength (E). PhET - Electric Field Hockey 18.5. Electric Field Lines: Multiple Charges Calculate the total force (magnitude and direction) exerted on a test charge from more than one charge Describe an electric field diagram of a positive point charge; of a negative point charge with twice the magnitude of positive charge Draw the electric field lines between two points of the same charge; between two points of opposite charge. 18.7. Conductors and Electric Fields in Static Equilibrium List the three properties of a conductor in electrostatic equilibrium. Explain the effect of an electric field on free charges in a conductor. Explain why no electric field may exist inside a conductor. Describe the electric field surrounding Earth. Explain what happens to an electric field applied to an irregular conductor. Describe how a lightning rod works. Explain how a metal car may protect passengers inside from the dangerous electric fields caused by a downed line touching the car.
