12-15

Taylor Husted Period 7 December 15, 2008 December 15th Today the objective in class was to take a "quest" (the mix between a quiz and a test). This quest covered the three types of vector problems. There was one question on the quest that dealt with vector addition, one that was answered with vector subtraction, and a final question that was how to find the forces using a right-angled triangle. A question used with subtraction could be found using one of two methods. The first method is subtraction by adding the opposite. This is where the second vector, or the vector being subtracted, is flipped to the opposite angle. For instance, if the second angle was 180 degrees, then you would simply flip it and the angle would be a 0 degrees instead. The second method that could have been used to find the answer to a subtracting vector problem, was the tail-to-tail method. This is where you place the two vectors head to head, and the final vector drawn will be the answer. This quest seemed like it would be a simple one, but once given the quest, one found that was not all true. Mr. Manning let us use our rulers, in centimeters, and our protractors, in degrees, to find the answers to the problems. Everyone seemed content with the quest, and no one asked any class-open questions. There are no homework assignments for tonight, but keep in mind a test may be coming up soon! So it would be in ones best interest to review daily the methods learned.
