Graphing Speed -
Will reviewed the graphs that represent constant motion and acceleration. He then graphed out the process of slow, variable speed, acceleration and then deceleration. We added these graphs to his notebook. He then was tasked with examining a graph of a car trip. The graph showed a line that was diagonal in some sections, horizontal in some sections and every section varied in slope and length. He identified where the car was traveling at a constant speed, accelerating, decelerating, and stationary. We then examined a graph showing the motion of several runners in a race; a single line represented each runner. Will was able to identify who won the race, who took a breather in the middle of the race and who was very much out of shape. Will was curious about the speed of sound, so we used some of this class to research the speed of light and sound, and why there is such a thing as a sonic boom.
