For each of the following sentences, draw a graph the corresponds to the motion being described (i.e. no motion, constant motion, speeding up or slowing down).

1) A hockey puck slides across the ice
2) A student drops out of Ms. Tanzman's window. There are no witnesses.
3) You've been driving your car, and you notice that Rite Aid is having a sale on hair gel and gold necklaces. You slam on the brakes.
4) "Yo bro," you remark via Facebook chat, "I'm just chillin'."

Describe the motion of each of these graphs:

1)

2)

3)

4)

In our investigate, Method B, you tested your reaction time by catching a ruler. You were also timing this part of the experiment with a stopwatch (another test of reaction time!). Let's find out how accurate you were!

Using the distances you recorded (NOT THE TIMES), use the following equation to calculate how long the ruler was falling.



d = distance the ruler falls (in cm)
g = acceleration of the ruler due to gravity (980 cm/s2)

Now, compare your calculated times to the times you recorded during your investigate. Are they the same? Why or why not?

Complete 'What Do You Think Now' and 'Essential Questions' on pages 16 & 17 of your textbook.

Take your hand-drawn graphs from today's lab (for Method A and B only) and re-graph them on the computer. Once you have your plot points, use a best-fit line to connect them. Then, find the slope (excel will do this for you) of each graph.

Also, come up with 3 new ways that you could measure someone's reaction time. Make sure that each method is scientific! How are you measuring each factor? How can you compare one trial to another?

By tomorrow, complete the following in your notebook:

• Answer chapter 1 'What Do You Think Questions' 
• Read and outline the Physics Talk and answer the Checking Up questions

Midterm Review

Gents-

At the bottom of the page, you will find a midterm review/practice powerpoint embeded using two different third-party webpages, to ensure that everyone could access it from your home computer or the school computers.

The quia midterm review can be found under 'Helpful Links'.

Don't forget - I will be around after exams tomorrow to answer any of your questions!

Thursday, January 10

Look over the worksheet you got in class today. Try to answer as many questions as you can. Come in with specific topics you want to review tomorrow.

Tuesday, January 8

Gents, we will have our chapter 5 quiz tomorrow (sections 1 & 2 only!). Look back over your physics talks, class notes, wave calculations worksheet and the physics to go questions.

I'll be in early tomorrow morning, if you want to ask me questions.

Midterm review on Thursday and Friday.

Update

Quiz has been moved to Wednesday. Work on wave calculations sheet for Tuesday's class.

Your instrument is still due on Tuesday. Also, here's the video that goes along with the current website picture:

Friday, January 4

Your insturment and write-up are due in class on Tuesday. Use the rubric I handed out and the guide on page 482 to help you.

We will also be having a quiz on chapter 5 on Tuesday. You should know the info from your notes, physics talk outlines and the wave calculation worksheet. We will have a quick review in class before the quiz so I can answer any of your lingering questions.

Thursday, January 3

For tomorrow you should have completed:

1) Checking Up questions (pg. 502)
2) What Do You Think Now? & Essential Questions (pg. 504)
3) Physics to Go questions 1-8 (pg. 505-506)
