1. WARM-UP:
NEW Behavior Log is filled out for 10/17/16
Copied Objective, HW into assignment list
WARM-UP:
If an object is held in the air, what kind of energy does it have?
Chemical
Kinetic
Potential
Electrical

2. Let’s Practice Together
The speed of an object undergoing constant velocity increases from 8 meters per second to 16 meters per second. If the object’s acceleration is 4 m/s2, how long does this change take?
        a. 2 s
        b. 4 s
        c. 8 s
        d. 32 s

3. Mantra - Your Turn! Today is a great day for science because:
Science is power.
We are powerful because:
We always make a difference.

4. Goals * State the Objective(s)/Standard (s)- RI 7.3; W2; Sci 2c
* State the Purpose (Big Idea) - SWBAT explain how movement is related to energy and work, and apply problem solving skills to real life situations as told in a pick-your-path-story.
SWBAT identify situational transition points between kinetic and potential stored energy and comprehend how it is related to work

5. Agenda I Do: Vocabulary/ Sample Problems We Do: Story Reading

Kinetic and Potential Energy, Lewin Demo’s
AP Physics Demo Videos
We Do: Story Reading
You Do: Checkpoint Problems
Review
Summary/ Feedback/ Questions

6. Forces *Fg= (mass) x (constant for gravity) *Fg = m g *g = 9.8
Gravity, Normal, Applied
Fg, FN, FA
*Fg= (mass) x (constant for gravity)
*Fg = m g
*g = 9.8
Free Body Diagrams
Level: Incline Plane:

7. Work Work= Force times distance times the angle of the force
W=Fdcos(Ø)
Units: Newton-meter (Nm) or Joule (J)
We care if the work is in the same or a different direction as gravity or motion, etc.
Simple Machines will probably make work easier!
Work Energy Theorem
Motion from A to B:
Work = Final Kinetic Energy – Initial Kinetic Energy
W= KEf-KEi
W= ( ½ mvf2 – ½ mvi2)

8. Energy Transfer of Energy Potential Energy
Kinetic to Potential (ie: rolling up)
Potential to Kinetic (ie: falling down)
Potential Energy
The potential of Gravity = (mass) x (gravity constant) x (height)
Ug=mgh

10. Last Items/ Questions Kinetic Energy exists in motion
Think about your progress and effort in Units 1 & 2 for Reflection/Celebration once grades are back
Kinetic Energy exists in motion
Potential Energy exists with height
Need Physics help or want to talk about your grades?
Office Hours Saturday, 12-1 at TBA!

11. GO GO FEEDBACK FRONTIER!
Miss K – In my baggie (Comments on my teaching, living up to my goals, and any personal things you need to privately tell me)
Your peers – Feedback to 1 or 2 people… What is something you saw him/her do that matched up with our class values? Why was it really great to see this?
