Week 1 - Kinematics
Homework Procedure: Read pages specified in Honors Physics Essentials by Dan Fullerton. Questions
labeled TQ will be questions about the text you read. These TQ’s can be answered in one word, one
phrase, or a complete sentence. Questions labeled CQ are conceptual questions and must be answered in
complete sentences. Questions labeled QQ’s are quantitative questions and the equation, substitution
with units, and solve with units must be shown on your paper. CQ’s and QQ’s will be similar to the
questions found in the Honors Physics Essentials textbook.
