TPJ Todays objectives were to pass back papers, Review Quiz, the Daily question, and to finish the Matchup Lab. We were given a handout, and it was called Driving Mr. Physics-VT Graphs. The quiz that was handed back was on on position-time graphs (XT Graphs) and was out of twenty nine points. The lab that was finished in class was combining different motions and speeds to match certain graphs that were given to us. You had to start at different positions, walk a certain speed, and move in either a positive or negative direction, or simply no direction at all. Once you figured out how you would move and at what times, you walked the setup and used a motion detector. This was hooked up to the computer, and sketched your movements on a graph. Once you felt like you portrayed the graph accurately like the one in the packet, you printed out each one and handed them in with the lab. The handout that was given in class was about VT graphs, which are known as velocity time graphs. We had to determine the characteristics of velocity, and know how to read it on a graph. We also had to answer questions about the graph, such as the speed they were traveling at, and the motion traveled.

This is an example of a VT graph, and notice that the velocity is the vertical (y) axis and time is the horizontal (x) axis. In this graph, the person or object moving starts moving at 0 m/s, and gets faster, moves at a constant speed for a while, and then begins to move slower.
