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 classTonight’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 POGILWork 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 IdeasInertia 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

If it is at rest. What does this mean?

o Zero velocityo Zero acceleration

Dynamic EquilibriumIf 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)!*

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?

POGIL- Moving ObjectsWork in groups of 4-5You 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

Go to your testing locations!Place your phones at the corner of your

desks (on silent!)You do not need a calculator for this quizYou will have 20 MINUTES to complete

this quiz! When you finish, place the quiz in the

inbox and continue working on the Mass v Weight Worksheet. **RETURN CLICKERS IN ORDER**
