10-16

As people walked into class you knew that it was going to be an excellent class period because the Phillies won and Mr. Manning loves the Phillies. To start off class we discussed about the packet we did the day before and for homework which was Driving Mr. Physics- VT Graphs. I was not in class the day before so I just listened and learned about the difference between VT graphs and XT graphs. While we were going over the VT graphs Annie had a question which was, "Why shouldn't it be negative if the line is going in a negative direction?" Mr. Manning answered "That as long as it is above the x-axis it is a positive direction and it is only a negative direction when it goes down in a XT graph." The Daily Question of the day was to describe in detail the following VT Graph:

It goes from a negative position to a positive. It is slowing down in the negative and speeding up in th positive. The starting velocity is -3m/s. It goes from a negative direction to a positive direction. At 4 seconds you stop and go in an opposite direction. The line picks up speed until you get to 5m/s in 6 seconds.

We ended class by finishing the XT Graphs of Objects in Free fall. We got on the computer and put the x-coordinates in and the y-coordinates. As we were doing these graphs Mr. Manning was handing back papers that were graded. He handed back the quiz we took on XT graphs and the Match up and Roundup Lab. While we were doing it Andrew put in the wrong time so our graph was wrong. He had to go back and switch them to the other time. This time our graph looked right. We printed it out right as the bell rang.
