PROCESSING THE DATA (Part A)
1. Describe the difference between the two lines on your graph made in Steps 4 and 5. Explain why the lines are different.
Answer: The lines were made different in the aspect that they first graph was for us to test the sensor and the second to test our skills to perceive if we can mimic something.
2. How would the graph change if you walked toward the Motion Detector rather than away from it? Test your answer.
Answer: It would spike lower due to the fact that moving away makes it rise. It did spike lower as predicted.
3. What did you have to do to match the graph you were given in Step 7?
Answer: We stopped for five seconds, walked backwards, stopped, walked backwards, and stopped once more.
PROCESSING THE DATA (Part B)
4. Describe the difference between the two lines on the graph made in Steps 10 and 11. Explain why the lines are different.
Answer: It was different because we had no control on matching the velocity. It was impossible to match in our opinion.
5. What is the definition of velocity?
Answer: Speed of motion, or action.
6. What did you have to do to match the graph you were given in Step 13? How well does your graph match the given graph?
Answer: We had to hold a constant speed to get a result close to what we were suppose to get.
PROCESSING THE DATA (Part C)
8. How does the acceleration vs. time graph differ from the other two graphs?
Answer: Acceleration differs in the fact that it doesn't matter where you are or what position you are in but how fast you are going.
9. What is acceleration?
Answer: Acceleration is the process of an object picking up speed as it travels over ground.
