 * The Objectives for the day were:**

Mr. Manning started off the day with the daily question"
 * Daily Question**:

Bellow we see a top view of an airplane being blown off course by wind in various directions. Use the parallelagram rule to show the resulting speed and direction of travel for each case. In Which case does the airplane travel fastest across the ground? Slowest?

The fastest plane to travel accross the ground is plane D. This is because the wind is coming from the back side pushing the plain in the most forward direction. The slowest plane to travel across the ground is C becuase the wind is hitting this plane pushing it almost backwards and slowing down the plane.

Component Notes and Worksheet:
 * Quiz Reminder: **Quiz Monday on vectors, everything drawing!!!**


 * The class then turns to the worksheet recieved in the begining of class, Pg 19. Manning goes on the explain components. A** component **is the resultant velocity and angle of two vectors. When vectors are at right angles to eachtoher it is called a** perpendicular vector**. Any vector can be broken down into its perpendicular components along the axes (North/South, East/West).

Mr. Manning warns the class that they will later need to find the lengths of these perpendicular components for future use. We can do this by drawing the original vector and then drawing the North/South axis component only as far out as the original vector goes. The same goes for the East/West axis.

That concludes our class period. Mr. Manning gives us the rest of the time to practice these perpendicular components with the following questions numbers one through four.
