12-12

Kim Humbard Today, Friday December 12th, 2008, we covered a new topic titled components. On the way into class, students picked up Pages 19 and 20 which were titled Components Note Worksheet. Students were then asked to answer the daily question, which was as follows: Because we see a top view of an airplane being blown off course by wind in various directions, use the parallelogramrule to show the resulting speed and direction of travel for each case. In which case dows the airplane travel the fastest across the ground? The Slowest? The black in the pictures below represent the direction of the plane, notice how it is always a 90 degree angle. The green represents the directions of the wind.



The answer to the first part of the question is letter D, while the answer to the second part is letter c. The reason that D would be moving the fastest is because the wind is going at a steeper angle, than any of the others. C is the slowest because the angle is the greatest in comparison to the others. The second thing that we covered in class was the quiz reminder. On Monday the class will have a quiz on vector addition, subtraction, and components. Make sure you study! The last topic covered was components, which is all about the worksheets 19 and 20. The rest of the class period was spent practicing components. Mr Manning also reminded any students who did not bring in their physics shirts checks to bring them in Monday.
