3. Your turn … Pick 2
Introduce yourself and pick 2 things to share with the class
Something factual
Favorite hobby / activity / unusual talent
Something interesting from the summer
Something about your family
Farthest / most exotic place you’ve traveled
Something you wish
Dream job (even if its not realistic)
Dream home / travel
Dream talent / experience

4. … in other words, everything!
WHAT is PHYSICS?
The study of matter, energy, and the interactions between them
… in other words, everything!
Physics is the study of
the very large …
the very small …
The little spring is meant to indicate that the quarks inside a nucleon are held together by a force we call gluon exchange.
It is sometimes said that Physics is the study of the ‘’essential nature of the universal” … other sciences build upon this basic foundation to examine the minutiae of narrower fields of study … the laws you learned in chemistry last year are, at their root, determined by the forces between the atoms and their component protons, neutrons, and electrons. Similarly, much of biology builds off the chemistry of organic molecules and their reactions. In this class, we will be focus on these basic laws of the universe from which all other sciences derive.
Extra time? Want them to talk more? Ask them to name a scientist … chances are they will name a physicist.
… and everything in between

5. The map of physics

6. Side Note On the Nature of Science
In this class, we will focus on classical physics, especially the basic laws of mechanics described by Isaac Newton 350 years ago
Newtonian mechanics successfully describes the motion and forces of objects in nearly all circumstances
The revolution of modern physics (quantum mechanics and relativity) came about when physicists began to realize that data on extremely small and/or fast moving objects didn’t fit existing theories.
Existing theories not only expanded our ability to
make predictions of physical phenomenon but
also revolutionized how we thought about the
nature of the universe.
Open – minded! LP for today!
Esp. interactions between time, energy, and matter.
“No amount of experimentation can ever prove me
right; a single experiment can prove me wrong”
-- Albert Einstein

7. Class structure Major Objectives Assessment
Understand physical phenomena not just equation hunt
Build problem-solving abilities
Communicate scientific knowledge simply and precisely using math, graphs, pictures, and words
Assessment
Daily work 30%
Labs & Projects 10%
Major Quizzes and Exams 60%
Estimate 30 minutes to this point
GROWTH! One of many reasons I love physics.
Work rule: ALL the time! EVEN when ‘you can do it in your head’.
No work or unintelligible work = no credit!

8. Class structure Rules Respect each other’s time and learning
Bring calculator every day!
NO computers or phones
Non-distracting food / drink is ok
Clean up after yourself
Sign in / out
Basic scientific calculators cost ~ $8 at Target, Walmart, or Amazon
Some very fancy calculators NOT allowed: not allowed if it has Qwerty key board, internet access, camera, or if I can’t figure out how to erase files / memory

9. Class structure Keys To Success
The challenge: Work through frustration and learn to engage in productive struggle.
Someone can show you how to do something 10, 20, or 30 times, but you won’t learn it as quickly or as deeply as you will if you figure it out on your own
Learn how to learn by studying resources (problems worked out in guided notes, physics classroom) . When in doubt, go back to concepts and understanding.
BUT, if you are struggling and not getting anywhere, then get help. After receiving help, try another problem on your own.
DON’T GIVE UP … studies say the single most important factor in success at any task is GRIT
Frustration is uncomfortable, not bad
Don’t get me wrong … I love helping students. But in the long term I can help you more if I teach you how to help yourself. I challenge you to work through frustration and think through the material, and I challenge myself to let you struggle … and succeed.

10. Unit 1: Vectors and Math skills Statement of Inquiry:
Math is a tool for explaining physical phenomenon
TOK Connection: To what extent does the common language and standard approach to measurement facilitate the sharing of knowledge in science?
Todays Objectives:
Define physics and recognize the types of phenomena studied
Recognize SI prefixes
Show syllabus online

11. About Measurements… Of course not! Two better ways:
The mass of the Earth is kg
Is this a reasonable way to express this measurement?
Of course not!
Two better ways:
5.972 X 1027 kg
-or –
5.972 X 103 Yg
where Y (Yotta) is the
SI prefix for 1024
**Interestingly, 1024 is the largest
SI prefix, but there is an ‘official’
Facebook petition to have SI
adopt “Hella” as 1027
There is an ‘official’ petition on facebook to establish ‘hella’ as the official SI prefix for 10^27

12. SI Units
What do I mean by SI units?? The International System of Units (abbreviated SI from French: Système international d'unités) is the modern form of the metric system adopted in Why use SI units? * universal * easy What are examples of SI units? * kg, s, m, L, etc.
OK if can’t do this. Leave 15 min for pretest.

13. SI Prefixes Power of 10 Prefix Name Symbol 10 -12 pico p 10 -9 nano n
micro µ
milli m
centi c
100 BASE UNIT, NO PREFIX
kilo k
mega M
giga G
tera T
Note:
These are prefixes. They go before the base unit (L, m, g, etc.)
What does the ‘power of 10’ column mean? !
It means how much of the base unit equals the prefix.
E.g m = 1 cm
1012 g = 1 Tg
