  1. Announcements 8/29/11 Close to Home: • Prayer • Introductions • This section: Physics majors and minors only! • For others, section 1 is in 445 MARB, right now • Signup sheet to be passed around • Willing to offer prayers in class • Willing to have phone number and/or email on a class directory

  2. Syllabus • Objectives. Five units: • Fluids • Thermodynamics • Waves/sound • Optics • Relativity

  3. Syllabus, cont. • Schedule • Reading assignments, lecture topics • HW/Lab/Term project due dates • Exams

  4. Syllabus, cont. • Grading • Guaranteed levels: • Categories

  5. Syllabus, cont. • Clicker quizzes • Two types of questions • Reading quizzes, 2 points if right, 1 point if attempted • Thought questions, 1 point if attempted • All questions from a day = 1 quiz • 4 free quizzes, no make-up quizzes • Register your clicker via class website ASAP! • Quizzes start next class period

  6. Syllabus, cont. • Exams, final, term project • More details later • Labs • Assignments at back of packet • First lab begins this Saturday • Typically 1 week to complete labs • Don’t count on being able to do it the last Saturday! • Extra credit • In syllabus, read about on your own

  7. Syllabus, cont. • Class website • www.physics.byu.edu → Courses → Class Web Pages → Physics 123 (Colton J) • http://www.physics.byu.edu/faculty/colton/courses/phy123-fall11/ • On website: • Study aids • Lecture notes • Demo videos • Old exams • Exam solutions • Obtain class ID number (“CID”) • Register clicker • HW submission • Check grade • Labs 3, 6 details • Term project details • Math review handout • Mathematica handout • Etc.

  8. Syllabus, cont. • Where to get help on homework • Other students • Dr. Colton’s office hours • MWF 2-3 pm (for now), Underground Lab study area under the skylight • If you don’t know where that is, there are directions in the syllabus • Chris Mackprang’s office hours • MW 5:30-7 pm, F 3:30-5 pm; same location as mine • The Tutorial Lab, 3rd floor of ESC (info on class webpage)

  9. Syllabus, cont. • Homework: paper-only vs computer-graded • The computer-graded HW system Syllabus packet contains problems: Get your missing numbers (“data”) from class website → Put in the [xx]______ spaces before you work the problem set 1. [01] 3.43 [02] 8.20 [03] 22.2 [04] 30.2 [05] 39.8 [06] 4.0 etc.

  10. Syllabus, cont. • Computer-graded HW system, cont. Answer range in packet, at end of list of problems: Indicates units, range and decimal places of answer 63.8 Type into website form: Submit all answers at once Partial credit, aka “retries” •  Points for each successive try: 5, 5, 3, 0 •  If you miss, correct answer is given to you • Use new data each time • No retries on multiple choice problems

  11. Syllabus, cont. • Final general HW comments: • Late HW • 4 free late ones, chosen to give you most pts • All other late HW is 50% • All work must be turned in, even for computer-graded problems • TA has 5 pts for each assignment at his discretion, for legibility/completeness/etc • Where to turn in work • Slot labeled “Phys 123, section 2” in boxes near room N375 ESC • Don’t put name on work, just your CID • First HW due Wednesday night! • My HW solutions – posted in hallway by CSR office

  12. And now, for the Physics… • Serway chapters 1-13, 15: Newtonian Mechanics • Covered in Physics 121 • Serway chapter 14: Fluids (static & moving) • Starting right now! • Then Thermodynamics (chapters 19-22) • Then other stuff

  13. Pressure • 1 Pascal = ?? • 1 atm = ?? • 1.013105 Pa • 14.70 psi

  14. Demos • Pressure vs. force • Collapsing can • Magdeburg hemispheres • von Guericke and the first vacuum pump, 1654 demo for Ferdinand III

  15. Density • Units? • Density of water: • 1000 kg/m3 = 1 g/cm3 • “Specific gravity”

  16. A Pressure vs. Depth • Weight of water above area A? (depth h) • Pressure at h: (include weight of air) Fluid pushes in all directions

  17. Summary • “How to get started” http://www.physics.byu.edu/faculty/colton/courses/phy123-fall11/ • Work hard!! (More Strange Quark comics at Dr. Durfee’s website, http://sqcomic.com )
