On a lab
group's cart for trial #1 and trial #2. (Both data sets on the same axis). Be sure to distinguish
between trial #l's data points and trial# 2's data points.
On a second sheet of graph paper, plot speed (y-axis) vs. time (x-axis) for the motion of your lab
groups cart for trial #1 and trial #2. (Both data sets on the same axis). Be sure to distinguish
benveen trial #1 's data points and trial# 2's data points.
From the plot of your graphs, The relationship between a sont

How can we tell from our plot of
speed vs. time, if the speed was
constant?
8. Describe some sources of error in
your experiment. Be specific and
explain. Do not list a source of
error that you can control, or
human error.
