Graphing your Motion Lab

Group with Greg Lundberg and Amber Kinnier

1. The faster we moved, the higher that the line began to rise.

2. The line would begin at the top and start to descend and the data would definitely change, because of how the graph was.

3. In the test, we had to stand still, then rapidly move backwards, then stand there and move just a little bit more, then stand completely still to be able to have the same results as the still in the example did.

4.  The difference between the two lines is that our velocity increased as we moved fast away from the sensor.

5. Velocity is a vector quantity that refers to "the rate at which an object changes it position."

6. To match the graph in the example, we had to keep a steady velocity , in order to match the graph. By moving slow and steadily backwards.

7. Walk backwards steadily then stop and start moving forwards, but just a little bit faster this time.

8. The acceleration vs. time graph differs, because it takes the other two pieces of data an uses them to record the acceleration. The graph is going to be more finicky than the others.

Skipped nine and ten and did the tasks in composition books.

11.Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity.
