### Studying Suggestions for Static Electricity Quiz

2013-2014

There will be a quiz on Friday, December 6. The quiz will be a one-page quiz, covering a both sides of a sheet of paper. Coulomb's law equation, Coulombs constant, and the charge of an electron will be provided. Other than a calculator, no other helps will be provided nor allowed. The quiz will be short and contain mostly multiple choice questions. Use of your book, your packet, the online resources at Multimedia Physics Studios, The Physics Classroom, and Minds On Physics should provide sufficient review. Students can expect the following concepts, skills, and problem-types to be assessed on this quiz:

1. Use an understanding of atomic structure to describe how objects can become charged either positively or negatively and explain how the law of conservation of charge applies to situations in which objects become charged.

2. Use the fundamental rule that like charges repel and opposite charges attract to conduct tests to verify that an object is positively or negatively charged; to apply this fundamental rule to explain electrical phenomenon.

Charge Interactions

3. Identify the Coulomb as a unit of charge and relate the quantity of charge on an object to the number of excess or deficient electrons; and use Coulomb's law as a guide to making qualitative predictions of the effect of one variable (quantity of charge and distance) and to solve simple computational problems.

4. Distinguish between conductors and insulators.

Conductors and Insulators

5. Identify and describe the method of charging objects by friction; use an understanding of conductors and insulators to explain in terms of electrons what happens when objects are charged by friction.

Charging by Friction

6. Identify and describe the method of charging objects by contact; use an understanding of conductors and insulators to explain in terms of electrons what happens when objects are charged by contact.

Charging by Conduction

7. Identify and describe the method of charging objects by induction; use an understanding of conductors and insulators to explain in terms of electrons what happens when objects are charged by induction

Charging by Induction

8. Identify and describe the grounding process; use an understanding of conductors and insulators to explain in terms of electrons what happens when an object is grounded.
