DAY 8

Warm-Up

1. What is the symbol for acceleration?

2. Can acceleration be negative, or only positive?

For each of the following P-t diagrams, copy the image into your warm-up. Then...

3. label each diagram as either: positive acceleration, negative acceleration, or constant acceleration. Assume movement towards the right is positive.

4. Directly underneath each diagram. add a position (dot) diagram, and a motion (vector arrows) diagram. An example of these is to the left of the projector screen.

5. How can you tell from a P-t diagram that an objects velocity is changing?

CLASSWORK

1. #007B (continued): Penny Acceleration Lab

Hypothesis

Data Collection

Results

Take a photo of your experimental setup

Tomorrow, we will discuss #007C: Speed, Average Velocity, Instantaneous Velocity Notes. Make sure you bring those notes to class...if you didn't do it, here's the instructions again.

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. Group: 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

HOMEWORK:

1. Tomorrow we will discuss your lab write-up, which will be due Tuesday. Bring your lab document to class.

2. #008A: Tomorrow we will also also practice walking through position-time diagrams. You'll need to be able to demonstrate what a position-time graph means, and we'll do that by having you walk (just like in the HW video)

Take Notes: LINK 1

3. #009A: Warm-Up Check is tomorrow. Including Friday's, you should have 9 warm-ups.
