Daily Agenda for November 15th and 16th
DO NOW:
• Take your clicker from the front of the class room
and return to your seat
• Take out your POGIL that you began for homework
from last class
Tonight’s Homework:
• Finish Mass v Weight handout (you’ll get this
later)
• Complete POGIL Activity if you did not finish in
class!
Review #1-7 in your POGIL
Work with others if needed-5 minutes to
review
 THINK…DISCUSS… QUESTION!!!
 Then, we will summarize the Big Idea from
the POGIL #1-7
 Any questions about #1-7?
 With the people around you…summarize
the BIG IDEA from #1-7…we will then
popcorn around the room
 What exactly IS inertia????

Big Ideas
 Inertia
is a measurement of MASS
◦ Directly related to mass
◦ More mass, more inertia…
◦ less mass, less inertia
 Inertia
is NOT affected by speed or
how fast

Inertia is a measurement of how RESISTANT to
change an object is.
◦ More mass = more resistant
◦ Less mass = less resistant
◦ DON”T TRY THIS AT HOME…But picture kicking a
bunny rabbit vs. a full grown hippo.
 Which is easier to get from rest to moving (in other
words, which is LESS RESISTANT to change?)
 The bunny! Less mass…less inertia…less RESISTANT to
change!
 Imagine they are BOTH running towards you at 50
mph. Which is more difficult for you to stop? (in other
words, which is MORE RESISTANT to change?)
 The hippo! More mass…more inertia…more RESISTANT to
change!
Mechanical Equilibrium ( ME)
Is when…
 The object is not changing its state of motion…
 so the object is not accelerating…
 and the net force on an object is zero.
And there are 2 types of it…
Static Equilibrium
Dynamic Equilibrium
If it is at rest.
 What does this mean?
o Zero velocity
o Zero acceleration
If it is moving in a
STRAIGHT LINE at a
CONSTANT SPEED.
 What does this mean?
o Constant velocity
o Zero acceleration
If I push a ball to the right with a force of 5 N
and you push towards the left with a force of
3N, what’s the net force? *Hint – draw a force
diagram (picture)!*
A. 2 N
B. 3 N
C. 5 N
D. 5N Left
E. 2N Right
F. 2N Left
G. 8 N
H. 15 N Up

Is this a mass, weight, or volume?
Mass Weight Volume T Chart
2000 lb race
car
2kg Discus
500ml Beaker
What’s the BIG idea?

What is the difference between Mass,
Weight, and Volume?

If I stood on a regular bathroom scale in
outer space, what would it read?

Does location affect my weight?
Go to #13 !!
What do we know?? (Look at Page 3)
POGIL- Moving Objects
Work in groups of 4-5
 You may work at a lab bench, but make
sure you are able to see the projector
 Work efficiently on these problems!
Whatever is not finished becomes
homework!
 At each
check in with a teacher. DO
NOT GO AHEAD UNTIL YOU
HAVE DONE SO.

What’s the BIG idea?
What is the difference between Mass,
Weight, and Volume?
Quantity of how much matter is in an
object. Units: g, kg, mg, etc.

Measurement of force of gravity
acting on an object. Units: pounds (lbs)
Newtons (N)
How much space an object takes up.
Units: cubic cm, Liters (L), cubic meters
If I stood on a regular bathroom scale
in outer space (aka weightless
environment), what would the scale
read?
A.
B.
C.
D.
E.
More than my weight
on earth
