Buggy Reflection
In physics class, it felt refreshing to do the Buggy labs yet again this year. From the lab, my group and I learned the the Buggy travels at a constant velocity (but some may argue that it is speed). In my lab, for every second, the position increased by 9.3 inches. This meant that the velocity is 9.3 inches/second. Both velocity and speed can be found by slope (but the speed will always be a positive number since it does not show direction).
In relation to the graphs, different graphs represented different situations. A graph with two parallel linear lines with different y-intercepts indicate that the velocity is the same, but it is just that the starting positions are different.
On the other hand, a graph with two perpendicular lines that intersect show that the two buggies travel at the same speed but at different velocities (because one line is positive and the other is negative). Also, the intercept of the lines show that the buggies are at the same position at the same time. However, if the two lines were not perpendicular with one line being positive and the other being negative, then the speed will be different. But, the fact that the intercept of the two lines indicates that the buggies are at the same position at the same time remain true.
In addition, a graph that shows two positive (or negative) lines with different slopes mean that the two buggies are traveling in the same direction, but just at different velocities.
Also, the y-intercept is the starting position of the buggy and (0,0) is the reference point.
All in all, despite the disagreements during the whiteboard discussion, I understood this lab and the meaning behind the data well. I have no questions.Thank you.
