HOMEWORK FOR LAB 1: INTRODUCTION TO IOLAB AND SOFTWARE

Please list the members of your group:

Make sure you use units, when necessary!

Answer the following questions in the spaces provided.

Question 1: In the position vs time graph to the right, an IOLab was allowed to run down a ramp, with the force sensor pointing down. At what time was the IOLab released? Please zoom in to the correct section.

Question 2: How long was the IOLab moving?

Question 3: What distance did the IOLab move? Please zoom in properly.

Question 4: The graph to the right shows the same experiment as on the previous slide: an IOLab was allowed to run down a ramp, with the force sensor pointing down. What was the maximum velocity before the IOLab was stopped? Please zoom in to the correct section.

Use complete sentences when you answer questions!

Question 5: How do you know?

Question 6: What is the average slope of the velocity vs.time graph while the IOLab is moving down the ramp? Highlight the section using the bar graph tool.

Question 7: The graph to the right shows the same experiment as on the previous slide: an IOLab was allowed to run down a ramp, with the force sensor pointing down. What was the average acceleration during the time the IOLab was moving down the ramp? Highlight the section using the bar graph tool.

Use complete sentences when you answer questions!

Question 8: How does your answer compared with the average slope of the velocity vs. time graph?

Question 9: The graph above shows an experiment where a student lifted the IOLab by the hook screwed into the force sensor. At what time did the student started to lift the IOLab?

Question 10: How do you know?

Question 11: When did the student put it down?

Question 12: You did the same in the lab. Can you comment on the value of the weight of this IOLab? Does this number look reasonable? What do you think could be the issue?

Question 13: The graph to the right shows an experiment where a student lifted the IOLab by the hook screwed into the force sensor. At what time did the student started to lift the IOLab? Please zoom in to the correct section.

Question 14: When did they put it down?

Question 15: Notice that the force sensor does not read zero prior to the student picking up the IOLab. This suggests that the IOLab was not properly zeroed. This can be remedied by doing the following:

1) Use the bar graph tool to highlight a section of the graph before the student picked up the IOLab.

2) Click on "rezero force sensor" which is just below the x axis in the graph.

There should now be a section of the graph reading a force of zero, which corresponds to the time before the student picked up the IOLab, and a section of the graph with a positive force, which corresponds to the time after the student picked up the IOLab. How much does the IOLab weigh?

ALL DONE!
