Graph Matching
introduction
one of the most effective methods of describing motion is to plot graphs of position, velocity, and acceleration vs. time. From such a graphical representation, it is possible to determine in what direction an object is going, how fast it is moving, how far an object traveled, and whether it is speeding up it slowing down. In this experiment, you will use motion detector to determine this information by plotting a plot a real time graph of your motion as you move across the classroom.
purpose
-analyze the motion of a student walking across the room
-predict, sketch , and test position vs. time kinematics graphs

3.an object moving in the negative direction with a constant speed
4.An object that is accelerating in the positive direction, starting from rest

negative direction
positive direction
positive acceleration
conclusion
For an object at rest, both velocity and position is a flat line, for a positive direction there is a negative line shown for both graphs, for a negative direction both lines on the graph are positive, and for positive acceleration both graphs start flat and grow steeper. Each graph is different and they all shoe a different "story" or what happens when we move away or toward the wall.
extension
When you go towards the wall the line is going to be negative and when you go away from the wall the line is positive. The steeper the line the faster you are going and the flatter the line is the slower you are going.
