Position vs. Time

This week in Physics, we did a lab that once again dealt with kinematics.  In the lab, we studied how motion worked in using a Motion Detector.  From using the Motion Detector, I learned that when an object stays in the same place for a certain amount of time, then the graph shows a line with a slope of 0.  When an object moves in a forward direction, the graph shows a decreasing slope.  When an object moves in a backwards direction, the graph shows an increasing slope.  So, in other words, I learned that the direction in which an object is moving and the time it takes to move that certain distance affects the direction of the graph.
