At the beginning of the period today (Tuesday, September 20), we turned in our Kinematics pair check worksheet if we had not done so already at the end of class Monday. We also checked our answers from Monday night’s homework, the “Kinematics Problem I” worksheet, which was graded for completion. After our homework was checked and we worked some problems, we completed an activity called “Following Jack”. Then, we took notes on graphing position vs. time graphs and velocity vs. time graphs. The next activity we did was on page 31 of our lab manuals. We played with cars (and tractors and space shuttles!) to perform what the graphs were representing. Following this, we started a lab called “Graphing the Look of Motion”, on pages 28-29 of the lab manual. We are going to finish this tomorrow in class. For homework, we were assigned a graphing exercises worksheet to turn in on Wednesday.
Answer to the QOD- Assuming that the truck is moving to the right, the position vs. time graph would be a curve with a positive slope, which shows changed velocity. The velocity vs. time graph (also assuming the truck is moving right), would have a straight line above the x-axis that continues on to show the constant acceleration.
