PHYS 2002 Lecture : Lecture1
Document Summary
It may still change slightly during this week. If you only have the 9th edition of the text, then you will need to purchase access to the 10th edition: orion adaptive learning engine. We will use turning point clickers in class: for quizzes & example problems, starting on wednesday. These slides will be posted on moodle before each class. Note: final date for students to drop a course without receiving a grade of w for the fall 2016 semester is august 30. Newton"s 2nd law: mass: property of an object, physics 2002: electrical charge. Can be positive or negative: electricity = flow of electrons. Electron charge is negative: -1e = -1. 602 10-19 c. Proton charge is positive: +1e = +1. 602 10-19 c. Extra particle inside the nucleus of other atoms. Two neutrons (charge 0: total charge: -2e+2e=0. Key idea: total negative charge of electrons equals total positive charge of nucleus: 1 electron has charge -e where e= 1. 602 10-19 c.
