DAY 15

Eighteen years ago, on this day, my Uncle Geoff and Aunt Judy were in Newark, NJ. Being hard working old people, they had booked a standby flight to leave earlier than their scheduled flight to San Francisco, Flight 93. They caught that earlier standby flight, and a few days ago, my uncle celebrated his 72nd  birthday. They were this close to being gone. So, try to live today and each day as your best version of yourself. Tell the folks you love that you care about them. Smile. Do good things. Cause, you never know what the future holds. 

-Mr. A

ESSENTIAL QUESTION:

What is motion? What factors influence how and why things move?

#Goals: SWBAT...

1. Interpret position-time graphs 

Warm-Up: (4 min)

If you watched the video for learning at home, this should be a simple review. If not, fingers crossed for you! :-/

Copy the position-time graph below. During which stage(s) is the object at rest? 

Classwork:

1. #015A: Position-Time Graphs Review & Notes (4 min)

Function: to express the location of an object at a specific time. 

Slope is the displacement AKA change in position (d) over the change in time, AKA the velocity

For the above example:

A: becoming more positive as time passes. It shows positive displacement, and therefore positive velocity

B. horizontal, so no displacement AKA "at rest"

C. becoming more positive as time passes. It shows positive displacement, and therefore positive velocity

D. horizontal, so no displacement AKA "at rest"

E. becoming more negative as time passes. It shows negative displacement, and therefore negative velocity

2. #015B: Chromebooks (8 min)

Copy your Chromebook number into your notes. 

Copy Chromebook norms (below) into notes. 

    - what's not appropriate

        - run

        - inappropriate things, like...

            - visit websites which are not school related

        - no liquids next to it

        - don't stack more than 2

        - don't charge your phone

    - what's appropriate:

        - use two hands

        - keep on desk

        - close when not using

        - charge when done

        - memorize your #

        - return to correct slot

3. #015C: Practice Position-Time (P-T) Graphs (30min)

    Use the Concept Builder linked below to build your skills

    You'll complete six questions from "Words and Graphs" and four questions from the "Speed Rankings" sections

    For each problem, number the problem, summarize the question (which stages show positive velocity? etc.), then copy the P-T Graph into your notes, and answer the question. QUESTIONS? Use the help button in the Concept Builder (how-to video here: LINK) or...ask me.

Learning at Home/HW

If you didn't finish the classwork, finish it at home. 

no video tonight :)

exam on all topics except distance/displacement, speed/velocity, & vectors/scalars is this friday. take tonight to study, look at old quizzes, etc. 

OLD STUFF BELOW - DISREGARD...

#Goals: SWBAT...

1. define free-fall without using the term, "force"

2. solve 1-D kinematics problems using the UAM equations.

Warm-Up (4min) 

• • 1. Give An Example of An Object in Free-Fall

• 1. If an object is in free-fall, is that an example of UAM?

  2. Why does Mr. P use the phrase, "the vacuum that you can breathe"?

  3. Define "free-fall" without using the word "force"

CLASSWORK

1. #015A: Notes: Representing Free-Fall with Graphs

    a. Draw a p-t graph. Draw a line representing the motion of an object in free-fall

    b. hint: does the position change more in the first second, or in the second second?

    c. revise if necessary

    d. Draw a v-t graph. Draw a line representing the motion of an object in free-fall.

    e. hint: does the velocity change more in the first second, more in the second second, or is the velocity change constant?

2. #015B: Practice Problems w/ Free-Fall

    - Solve 14 & 16 here: http://www.physicsclassroom.com/Class/1DKin/U1L6d.cfm 

    - Use GUESS

At Home Learning (HW) 

**This weekend, expect to start seeing grades in schoology. Probably not all grades, as this is my b-day weekend, and my daughter's as well.** (I like Coke and Almond Joy ;-)

1. #015B practice problems. If you didn't complete this in class...do it for HW

    - use GUESS

    - solve # 14 & 16

    - LINK - The Physics Classroom

2. #015C: Tuesday we will attempt more complicated Free Fall problems as we build towards our ramp/cup/ball bearing challenge
