Cycle II Regents Physics

John Dewey High School

Mr. Klimetz

Success on the upcoming NYS Regents examination in Physics as well as on classroom quizzes and tests necessitates thorough familiarity with the newly published *Reference Tables for Physical Setting/Physics 2006 Edition.* This document supersedes the previous *Reference Tables for Physics,* particularly the edition last used for the January, 2002 Physics Regents exam. The following exercise is designed to assist you becoming more familiar with the new *Reference Tables* as an essential data source in Physics problem-solving. Bear in mind that solutions to each of the following twenty multiple choice questions relies in some way on information provided in the *Reference* *Tables. *Therefore, you must have your *Reference Tables* alongside you in order to complete this exercise. Place the answers to each question in the left-hand margin adjacent to the respective question number.
