Lesson Plan and 3mQ for Pre-AP Physics week 09/12/11

MONDAY: Today we focus on free fall and what that means in terms of forces and accelerations. We will define free fall and then learn what free fall acceleration is. Next, we will look at p-t and v-t graphs of free fall and then look at PP 2E. What is not finished in class needs to be finished for homework. Tomorrow we will review what needs reviewing for the test on Wednesday. How far along are you on the FPs?

TUESDAY: This is our last chance for review for the test tomorrow. We will review the equations for this chapter and how we have been using them. If you have worked the FPs we can check them today. If you have not worked them we will see what we can get done today.

WEDNESDAY: Take the conceptual portion of the chapter 2 test. Homework: Prepare for the Problems portion of the chapter 2 test. Review those FPs!

THURSDAY: Take the Problems portion of the chapter 2 test. Homework: Download the Reaction Time lab here and review it before tomorrow’s class. Your review should be good enough to answer today’s 3mQ, which you will do for homework. You will be helped greatly if you read the “Quick Lab” on page 62. We have only two class days to work on this lab. It is essential that you review this lab before class. In addition, download and review the Job Description for Lab here. If you do not have this or the lab tomorrow you will be left behind.

FRIDAY: Today we will start the reaction time lab. Your group needs to get to #6 before NAT can begin for you. Before the end of class the RC must show Mr. Young the list of who is doing what part of the lab report, which is due next Wednesday.

3mQ PAPP 09/12/11

1. What is the single force that is acting on an object that is in free fall?

2. Put these objects into a list of “objects in free fall” and “objects not in free fall”: (a) an object thrown straight up, (b) an object dropped from a window, (c) a curveball pitched to a batter, (d) a massive steel ball bearing thrown to a student, (e) an airplane coming in for a landing, (f) a bird in flight, (g) a satellite in orbit around Earth, (h) Earth in orbit around the sun, (i) the sun, (j) The Milky Way Galaxy

3. What is the acceleration due to gravity for all objects on Earth at sea level?

BONUS: Sketch a v-t graph for an object that is thrown up and comes back down; what is the slope of the line on this graph? Convert this to a p-t graph.

3mQ PAPP 09/13/11

Note the v-t graph at the left:

During what time interval is the acceleration zero? What happens at t = 6s?
Calculate the acceleration of the object.
What is the total displacement of the object?

BONUS: Sketch what this graph would look like if it were a p-t graph.

3mQ PAPP 09/15/11

What single measurement will you take in order to measure your reaction time?
What single tool will you be using to measure your reaction time?
Describe what you will do with this tool so that your reaction time can be measured.

BONUS: What equation will you use along with what bit of data to calculate your reaction time?
