Introduce team. Stacey teacher of record.
Students pair up and introduce the person
next to you – something interesting about
them or something no one knows. 1 min, 1 min,
30 sec.
One simple rule – if it helps education, good,
if not, bad.
Course syllabus – need signature.
Describe PPT project - why, especially that it
is research. Film, pics, people, we’ll be testing
out material, so…

Quiz on inertia
How do you measure inertia?
What has more inertia, a 1 kg cannonball
traveling 500 m/s, or a 7 kg bowling ball
rolling at 10 m/s?
What is inertia?
How does constant velocity relate to
inertia?
Discuss Galileo, Aristotle, inertia
Friction activity and summary questions
Friction is a force
Friction results from contact between two
objects
friction affects motion
friction is everywhere
static friction increases until sliding starts
static friction > sliding friction
sliding friction is constant
friction increases proportionally with the
force between the objects (weight)
friction varies with the surface
friction is independent of area

Test Tuesday?
Quiz
Why do the lab when we can tell them F=ma?
To get a FEEL for why it works, To have
hands-on/ better memory. To learn science.
To learn how to figure things out. To see
what the original guys had to do.
Lecture on Newton finding F=ma. aF/m
Units are kgm/s2
F=ma for weight or pull. What is a? Hence
.070kg -> 0.7N

Gravity is force of attraction between
masses
All objects have mass & gravity. More mass
means more gravity.
Weight is a force. F=ma
Calculate weight knowing a of gravity. F=m
Difference between mass & weight. g
WU - What is mass? (Stuff)
WU - What is inertia? (A property)
P4 - WU - What is gravity? (A property)
WU - What is weight? (A force, mg)
WU - What is the difference between mass
and weight?
Mass has inertia and gravity. (Einstein said
they're the same.)
WU - How would you find the mass of
something? The point is arbitrary definitions.
Show a balance beam scale. mg=mg,
20.5mg=1mg
Just for fun, Discuss standards for mass,
distance, and time - from Giancoli
Summary - Why would an object weigh less on
the moon than on Earth?

Center of mass

points:
A standing object is stable if the CM is above
the base of support.
De-brief L lab
Center of mass
Quarterly reports
CM worksheet and exercises
CM review
POST ANSWERS? Summary and exercises.
De-brief CM lab & HW
Every mass has a CM
The CM is the balance point, average of the
mass, all the mass is evenly distributed
around the CM.
The object acts as if all the mass is at the
CM for both inertia and gravity.
The CM hangs directly below the suspension
point. Why? Torque from Fg.
If the CM is above the base, it's stable.
CM does NOT mean that there's equal mass
on all sides (use demo)
Apply CM to physiology
Ronel take test at lunch

Quiz
Review physiological CM exercises
CM can move within an object
Draw a base of support showing feet
Draw a line through Earth CM and object CM.
For freely-supported object, CM is always on
that line.
Ruler balance - do in stages. Hand out sheet
Bend paper clips, 5 total, as shown
Calculations of CM, ∑md = ∑md
Review quiz #3, CM not in center - density
#4, change CM by bending wire into circle.
Ruler balance continuation
Summarize first part, md = md
m and d are inversely proportional, so mult.
Look at each combo by itself. No absolute #s.

Derive levers formula - try in mks, using N
Class 1 should be easy, just like CM
Class 2 - farther is easier, up to F of R
Class 3 - starts w/ F of R, increases to 
Make a class graph of class 3s to show a
hyperbola

Work is Fd, so lifting distance.
PE is energy of position, so we’re looking at
height.
KE is energy of motion, so we’re looking at
speed.
Work is Fd, and sliding friction is constant
force, so distance can represent that.
