2 Physics 121 a physics survey course designed for physics and engineering majors. The topics of vectors, linear and multi-dimensional motion, work, energy, gravitation, simple harmonic motion, conservation of momentum and energy, constant acceleration motion, rotational motion, thermodynamics, and waves, will be covered at an introductory university level with some introduction to mathematical techniques used in more advanced courses. Students are assumed to have some knowledge of calculus, though the techniques will be reviewed as they are used. No previous physics instruction is assumed. … is Surgeon General’s warning: No matter what you’re smoking, this is not your high school course.

3 Professor Steven Manly B&L 203E Name University … ) address favorite midnight snack favorite novel Why are you in this course? See syllabus/info writeup

4 Why are You here? It is a requirement for my major. This hot girl down the hall said she was taking it, so I figured... I like physics, did great in high school. I haven’t a clue. I want to be an engineer and computers do their calculations.

5 Why is this a requirement for your major? fluid flow, arteries, water fountains, commodes mechanics of breathing, walking, running, flying, standing all sports: curve balls, spin in tennis, drag in swimming, etc. Motors, gears, wheels, ambulances, bikes buildings, doors, bridges, skeletons Chemical bond modeling planes, boats gravity All engineering calculations/models are based on physics.

6 Why do I think you are here? Awareness and respect for physics in the real (your) world To learn to solve problems. To pick up many of the basic principles and techniques that will carry you through future courses in physics and engineering.

7 “It is not so very important for a person to learn facts. For that he does not really need a college. He can learn them from books. The value of an education in a liberal arts college is not the learning of many facts but the training of the mind to think something that cannot be learned from textbooks.” - Albert Einstein, 1921, commenting on Thomas Edison’s opinion that a college education is useless.

9 Hidden slide: notes for discussion of recipe analogy Why hard? Lack of experience, lack of confidence, language, prior knowledge, equipment which is harder? Why Can you make bread following a recipe? Would you feel confident changing the recipe to make a different kind of bread? Suppose the bread didn’t work out, would you know what to change to make it work next time? What are the similarities in the recipes? What is essential and what can be changed? What is the essence of what happens with each ingredient/step?

10 Components of the course: Lecture Concepts, depth, association with the rest of life, other disciplines, systematic technique, gotchas, class issues, hints, some problem solving

11 Components of the course: Lecture Lab Not as integrated as we would like. Part of your P121 grade. Must do all 5 labs to get a grade in P121.

12 Components of the course: Lecture Lab Text More depth and associations, different approach, problems, not a substitute for lecture or doing problem sets

13 Components of the course: Lecture Lab Text Problem sets Absolutely critical that you struggle with them and follow thru on particular personal questions/issues, taken up and graded for effort only

14 Components of the course: Lecture Lab Text Problem sets Workshop My way to help you help yourself!

15 Components of the course: Lecture Lab Text Problem sets Workshop Project A fun break from the analytical.

16 Components of the course: Lecture Lab Text Problem sets Workshop Project Exams
