1. Using Table 1, graph time (on the horizontal axis) versus distance (vertical axis). Be sure to
include all of the necessary components: optimal use of 1/2 of one page, data points indicated by
circled dots, labeled axes including units in parentheses, title, and a smooth "best fit"
interpretation (line) of the relationship between the variables.
2. Again using Table 1, draw a second graph of time squared versus distance. If either of these
graphs appears to indicate a linear relationship between the two variables, determine what the
slope of the line is and include units in your answer._____________________
3. In the Temperature Probe section of the lab, how many data points are to be collected and at
what interval?
a. Number of points:____________
b. Interval (seconds):____________
4. In the Force Sensor part of the lab, how many data points will be collected if the sample
interval is 0.02 seconds and we sample for a total of 3.6 seconds?
5. What is the range of the motion detector? _______________meters.
