At the start of class, we turned in the Chapter 2.1-2.2 guided reading worksheet and the kinematics discovery lab. Then we were given a handout over kinnematics. We went through problems 1-4, answering the questions as a class. These notes reinforced basic definitions such as; xi=initial position, v= rate, etc.. These problems were for us to get used to making our own equations from information given and how to use these equations, either to find a specific meeting point of two constant moving objects or a time in which they would meet. For number 3, we made the problem more of a story by making Mr. Hume be the car and Emily be the other car (bus) driving the Spark kids from West Chester to Dayton. Afterward we continued with a pair check. Most students did not finish the pair check and that became additional homework to the Kinematics Problems 1 wkst. Both are due tomorrow.
Question of the Day: You are running from a bear. At first, you speed up because you want to get away, but eventually you slow down because you get tired. If you survived this experience and plotted your motion on a graph of position vs. time, would it be appropriate to draw a straight line through your data points?
Answer: No, it would not be appropriate to draw a straight line through the data points because you were not traveling at a constant speed so the motion was not uniform.
