1. Daily Agenda for November 15th and 16th Daily Agenda for November 15 th and 16 th 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!

2. 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????

3. 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

4. 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!

5. 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 velocity o Zero acceleration Dynamic Equilibrium If it is moving in a STRAIGHT LINE at a CONSTANT SPEED.  What does this mean? o Constant velocity o Zero acceleration

6. 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

7. This object is in…. 10N A. Mechanical Equilibrium B. Static Equilibrium C. Dynamic Equilibrium D. It is not in Equilibrium! E. Not sure

And there are 2 types of it… Static Equilibrium If it is at rest.  What does this mean? o Zero velocity o Zero acceleration Dynamic Equilibrium If it is moving in a STRAIGHT LINE at a CONSTANT SPEED.  What does this mean? o Constant velocity o Zero acceleration

9. This stationary object is in…. A. Mechanical Equilibrium B. Static Equilibrium C. Dynamic Equilibrium D. It is not in Equilibrium! E. Not sure 10N

10. 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 velocity o Zero acceleration Dynamic Equilibrium If it is moving in a STRAIGHT LINE at a CONSTANT SPEED.  What does this mean? o Constant velocity o Zero acceleration

11. A. Mechanical Equilibrium B. Static Equilibrium C. Dynamic Equilibrium D. It is not in Equilibrium! E. Not sure 10N This moving object is in….

13. A. Mechanical Equilibrium B. Static Equilibrium C. Dynamic Equilibrium D. It is not in Equilibrium! E. Not sure 10N This moving object is in….

14. Is this a mass, weight, or volume?

15. Mass Weight Volume T Chart 2000 lb race car 2kg Discus 500ml Beaker

16. 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?

18. Go to #13 !! What do we know?? (Look at Page 3)

19. 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.

20. 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

21. If I stood on a regular bathroom scale in outer space (aka weightless environment), what would the scale read? A. More than my weight on earth B. Less than my weight on earth C. My weight on earth D. Zero E. Not sure

22. What’s the BIG idea? If I stood on a regular bathroom scale in outer space (aka weightless environment), what would the scale read?

23. Does location affect my WEIGHT? A. YES B. NO C. Not sure

24. Does location affect my MASS? A. YES B. NO C. Not sure

25. Go to your testing locations! Place your phones at the corner of your desks (on silent!) You do not need a calculator for this quiz You 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** Tonight’s Homework Finish POGIL activity Moving Objects Complete Mass v Weight worksheet for homework! This will be checked and reviewed next class so have it done!
