Welcome, roll, questions
Finish Debate Planning from yesterday
Introduction to Energy in Physics
Calculus is the language of physics
ConcepTests and Peer Instruction
CAL: HW on eGrade
Looking ahead
Energy Systems, EJZ
Finish debate planning
• Groups report on question or statement to
be debated
• Draw for Pro or Con side
• Tonight on WebX, each group should
–
–
–
–
–
create an online Discussion with your team’s
Topic = title
Debate statement or question
Names of Pro, Con, and Facilitator teams
Everyone’s phone number and email
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
