Free Fall Lab

Today we are working on the Free Fall Lab. First I went over exactly why we are doing this lab and introduced the idea of linearization. The rest of the period was yours to take data, including about half an hour of the whole class going outside to drop the balls off of the bleachers.

To save time (and prevent the loss of the Koosh balls through a certain fence) the whole class timed the ball drops from the tallest bleachers as a group.

You have no additional homework tonight. This is due in one week (your next modular day). Please remember that you have a test scheduled on Friday.

Problem Solving Method

Today we went through a problem solving method for story problems. You don't have to use this method, but I recommend using it at least at first.

Notes: Solving Kinematics Word Problems

Homework is p.52 #37, 43, 46, 51, 54.

We will be doing a lab on Monday/Tuesday. Please read over the lab instructions this weekend and bring your lab notebook to school.

Part of the lab will be outside. You may want to bring sun protection.

1-D Motion Equations

Today we finally got some equations that will let us solve for position, velocity, and acceleration at a given time.

Notes:1-D Motion

Homework is p.52 #31, 33 a&b, 45

Graphs of Motion - Backwards!

More graphs! Just going from acceleration to velocity to position instead!

Notes: Graphs of Motion-Backwards

Homework is Kinematics TIPERs #3. Email me for an electronic copy if you need it.

Acceleration and Graphs of Motion

During bellwork we talked about your Constant Velocity labs (due tomorrow) and also made our first velocity vs. time graph. Then we defined acceleration, looked at how it affects motion diagrams, and made acceleration vs. time graphs out of velocity vs. time graphs.

Here is the Powerpoint: Acceleration and Graphs of Motion

Homework is p.51 #24 and p. 55A # 1&2 (55A is a special page only in the "AP Edition" of the textbook. You might not have it in your textbook; contact me if you do not and I will send you a picture)

Below are the answers for the bellwork.

Constant Velocity Lab

Today you worked on the Constant Velocity Lab! Your individual write-up is due next Wednesday. Remember, you can only use one car at a time, so no trial and error!

You may hand write your paper, or you can type it and email it to me.

Velocity and Graphs

Today we used graphs to find both average velocity and instantaneous velocity. The notes about instantaneous velocity included a graph on the whiteboard.

Homework tonight is the half-sheet HW: Velocity. It contains copyrighted material, however, so I cannot post it on the internet. If you need a copy, email miss.volkening@gmail.com and I can send you a PDF scan.

We also received the instructions for the lab we're doing tomorrow, Constant Velocity Lab. You will have all day tomorrow to work on this.
