1. Welcome to PHSC 2014: General Physics 1 PHSC 2015: Calc-Based Physics 1

2. Subject Matter The secrets of the Universe

3. What’s the Point? Physics is basic Physics is the secrets of the universe Physics is problem-solving

4. Subjects Mechanics –forces and responses –interactions and collisions –repositioning and rotating –uniform and accelerated rotation –gravity –conservation laws

5. Subjects Fluids –pressure –buoyancy –flow Oscillations –simple harmonic oscillators –damped and driven oscillators

6. Subjects Waves –limiting types: longitudinal and transverse –factors determining speed –interference: standing waves and beats –Doppler effect Heat and Temperature –arrow of time –engines

7. Who are You? Please clearly write your first and last name on the tent card Please bring your tent card to every class Your Name First Last

8. Group Work Introduce yourself to your group. Identify something memorable about yourself your home town your family your name or anything else associated with you Tell your group and write it down.

9. Mechanics of the Course

10. PHSC 2015: Calculus-Based We need to find another hour to meet each week Any suggestions?

11. Standards-based grading Scored on standards, not points The more standards you meet, the higher your final grade

12. Meeting the Standards Last assessment matters Don’t blow off early assessments: learn! If lots of folks miss a standard, I’ll re-quiz If you personally miss a standard: –Work some more problems –See me for a re-assessment I want you to succeed.

13. Quizzes In class May be announced or unannounced Assess on standards (no numeric score)

14. Scores on Standards NNot assessed INot eligible for reassessment EEligible for reassessment P Progressing SSatisfactory S is the only score satisfying a standard Other scores tell what needs to happen X

15. Labs Tuesdays 10–noon, 1–3, 3–5 Room HSC 111 (downstairs) First labs tomorrow Manual on-line for now Must meet lab standards for grade

16. Homework No points: for practice Required for retaking standards Additional exercises may also be required for retakes

17. Textbook and Lab Manual Textbook: Walker, Physics, 4th ed. (req.) Lab Book: Physics I Laboratory Manual (pending)

18. How to Succeed

19. Read the Textbook Read before class Study after

20. Prepare for Lab Read manual before lab Do pre-lab (due at start of lab)

21. Do the Homework Possibly online exercises Turn in written part in class Late submissions don’t get feedback

22. Use Web Resources Class web site –www.barransclass.com/phsc2014www.barransclass.com/ph –Syllabus, standards, PowerPoints Balckboard –Scores (I hope I can do standards there)

23. Visit Me Heimerman Science center room 119 Hours: MWF1–2 PM T9–10 AM or by appointment or come in if my door is open

24. The Science of Physics the fundamental quantities

25. Quantities and Units Distancemeter (m) Masskilogram (kg) Timesecond (s) Chargecoulomb (C) SI (International System) or MKS units QuantityUnit

26. Working with Units Math makes sense

27. Eat a live bullfrog first thing in the morning… …and nothing worse will happen to you for the rest of the day!

28. Do math with units Unit labels can be treated like any variable in algebra. Add them! 3 x + 4 x = 7 x 3 s + 4 s = 7 s Multiply them! (3a)(4b) = 12 ab (3 m/s)(4 s) = 12 m = 3 x/y 6 x 2 y = 3 J/s 6 J 2 s Divide them!

29. Compound Units Areas Volumes Accumulated effects Effects of population Represent:

30. Compound Units a b Area = ab

31. Compound Units 3 workers Effort= (3 w) (4 h) = 12 (w)(h) = 12 worker·hours 4 h

32. Ratio Units Rates of change Intrinsic properties Represent:

33. Ratio Units A baby has a mass of 3.2 kg at birth and 8.6 kg 9 months later. What is its average annual growth rate during this time? slope = 5.4 kg 0.75 y = 7.2 kg/y mass (kg) time (y) 10 8 6 4 2 0 01 0.75 y 5.4 kg

34. Manipulating Units Conversions 39.37 in = 1 m 72 in equality conversion factors = 72 in · 1 = 39.37 in 1 m 1= 1 39.37 in = 72 in · 1 m 39.37 in = 72 39.37 m = 1.829 m

35. Group Work 2.1 mi = 5280 ft 1 yd = 3 ft Set up the conversion 2 mi to yd. 3.1 mi = 5280 ft 1 ft = 12 in 1 m = 39.37 in 1 h = 3600 s Set up the conversion 75 mi/h to m/s.

36. Reading for Next Time Distance, velocity, and acceleration: how physics describes motion Keep in mind the relations between different quantities
