DAY 7

***I'm still sick, and won't be talking much, so make sure you participate to keep the energy high!***

Essential Questions: 

1. How do I do math in physics?

#GOALS: SWBAT...

1. Correctly use the mathematical tools needed to make conversions

2. Define accuracy and precision

3. Score 100% on the quiz

WARM-UP:

1. Is your mass the same wherever you go, or does it change if you travel to another planet?

2. Find your mass in slugs. Use the steps below:

1. Find your weight (in pounds on Earth).

   1. Find gravitational acceleration on Earth in ft/s2.

   2. Use the equation below in which:

   3. g = gravitational acceleration of Earth (ft/s2)

   4. F = equals your weight (lbs)

   5. m = your mass in slugs (English unit)

OLD STUFF BELOW

#GOALS: IWBAT...

1. Define the components of the acceleration equation

2. Solve an acceleration problem using the GUESS method

WARM-UP:

1. Review the image of the rock falling from the cliff (LINK)

2. Is the rock moving at a constant velocity? (Y/N)

3. How can you tell?

4. What does the text call this example of falling without resistance?

5. Copy the Two Rules for Free-Fall:

CLASSWORK

1. HW Questions?

2. #007A: Acceleration Notes (10 min)

   • Go to page two (LINK). Answer the following in your notes

     1. what is the magnitude of g? direction?

     2. Find and record the value of g here in LA, and for Barrow, AK. 

        1. Are they the same g? Why/why not? (hint: LINK)

     3. Copy the equation for acceleration

     4. What is the pattern for change in velocity shown in the Time / Velocity chart

• 1. #007B: Penny Acceleration Lab

  2.     Hypothesis

  3.     Data Collection

  4.     

HOMEWORK

#007B: Lab Calculation

For your data in "1 penny 1 m", find the average time for all three results, then use that average t to solve for the acceleration.

#007C: Speed, Average Velocity, Instantaneous Velocity Notes (& Future Discussion)

    The goal here is for you to memorize and then translate some information about speed and velocity. By doing so, I hope you'll understand the similarities and differences between instantaneous and average velocity, between speed and velocity, and be able to describe some of those factoids out loud, with confidence. Here we go...

    a. you'll need a notes page in your binder. The title is in bold above

    b. Individually: while skimming, I want you to write down 5 facts, similarities, or differences you've found. Facts could include symbols, equations, definitions, descriptions, etc.

    c. Group: Tomorrow, in your group, each person will choose one fact, similarity, or difference, and read it out loud. Don't be super loud. We don't all need to hear you ;-). Listeners should either check the item off on their notes if they have the same bit of info already written down, or add it to their list if they don't. The idea here is that you as a listener have to compare what you have written, and how you interpreted it, to how someone else interpreted it. This helps improve your comprehension. 

    d. Whole class: We will repeat "c" as a class

    e. So, what's the reading??? CH2, pg 43-47
