Intro to Energy in Physics What sorts of Energy can you think of? Discuss energy transformations and flows Preview of physics description of energy We’ll lay basics physics and calculus groundwork these first few weeks, then We’ll dig into energy details starting week 4

Calculus is the language of Physics Precalculus review for the first two weeks We’ll spend two weeks per chapter –First week: formal introduction to material, first HW –Second week: a little new material, second HW on same chapter If you are ready for more challenge in calculus now: –Work ahead on homework first – is it quick and easy? –Then talk with Zita after class –Keep busy meanwhile by working harder problems from our text

Calculus Ch.1 Precalculus review: Functions, including e and ln ConcepTests Introduce material  practice examples Strategy for doing homework (HW) and learning: Skim text the first time Come to class and start learning new material Try all the problems independently Read text more carefully to figure out problems Bring questions to your team and to class Finish HW independently (online)

Calculus Ch.1: ConcepTests Goals: Engage students directly in thinking about new material Teach faculty where students are starting out Practice articulating our developing understanding 15 seconds to pick an answer Quick vote 1 minute discussion with classmate Revote Discuss solutions

Calculus Ch.1: Functions Functions describe relationships Domain = independent variable, range = dep ConcepTests 1-3 Ex: Crickets chirp faster when it’s warmer Interpreting graph Finding slope Equation for linear function ConcepTests 4-16, 20 Practice homework in teams Homework discussion

Calculus Ch.1: Functions – cont’d Ex: Mexico’s population increased by 2.6% yr Graph, slope, equation Exponential function ConcepTests, HW practice 1.3: New functions from old: shift, stretch … Ex: Oil slick area depends on growing radius ConcepTests + HW practice Even and odd; Inverse functions ConcepTests + HW practice
