Before starting the quiz, make sure you have completed all module activities with additional emphasis on the following: The textbook is essential for this course. Read Chapter 1 and be sure you understand the solved problems in the chapter. Actively (with paper and pencil) work through this module's 1st video ( entitled Solving Physics Problems ) that introduces the 5-step problem-solving technique used throughout this course. This module's additional videos are also helpful. Successfully complete the problems in the textbook End-of-Chapter Problems section. This is an essential step in preparing for this Chapter Quiz. The End-of-Chapter Questions section is also helpful. Quiz Instructions 1. Use 9.8 m/s for g (the acceleration due to gravity). 2. Use the conversion factors found in the back of the textbook (not those found on the internet). 3. Answers should be solved in SI units unless other instructions are given in the question. 4. Do not include units in your answer ( numbers only ). 5. Express answers to 3 significant figures unless other instructions are given in the question. 6. To enter an answer in scientific notation in Canvas, use lower-case "e". For example, 6.02 x 10 would be entered as 6.02e+23. A. "+" is optional for positive exponents. B. Do not include spaces in your answer. Questions are presented one at a time. Use caution in navigating back to a previous question – answers are only saved by selecting the Save button or navigating forward to the next question. Attempts: You will have three attempts to take this quiz. After a first wrong answer a hint is provided to help get started but additional steps, including unit conversions, may be needed.
