All answers must be in complete sentences.
  1. Describe the motion of your object for run one. State whether the object is moving at constant speed or if its speed is changing. Use the appearance of the position vs time graph to support your answer.


  2. Repeat for run three.


  3. How does the appearance of the position vs time graphs for run one and for run two indicate that the car was moving away from or approaching the motion sensor?


  4. In your position vs time graphs, why was position used as the dependent variable (y) and time used as the independent variable (x)?


  5. What variable in physics does the slope of the position vs time graph represent? Support your answer using the definition of this variable.


Conclusion: In your conclusion, answer the purpose in complete sentences. State what value that you found for the velocity of the object in runs one and two. State what was different about the motion of the object in run three, citing a supporting reason.
