9.
Repeat Step 8 using a force of –1.0 N.
10.
Print copies of each graph.
Trial 2
11.
Attach a mass of approximately 0.500 kg to the cart.
Record the mass of the cart, sensors,
and additional mass in the data table.

ANALYSIS
Create and save graphs of force vs. time and acceleration vs. time for each
trial.
Create and save a graph of force vs. acceleration (with linear fit data) for each
trial.
Include all graphs in your report [6 total].

CONCLUSIONS
1.
State in your own words the results of the experiment. Be specific —
cite numerical and
graphical results and discuss the meaning or significance of the results.
Include a statement
concerning percent error and sources of error when applicable.
A possible source of error is pulling the cart at an angle above the horizontal.
2.Compare the graphs of force vs.time and acceleration vs.time for a particular trial. How are they different (aside from the obvious fact that they are different values being recorded at the same time)? How are they the same? NOTE: Calculations are not necessary to answer this question. Descriptions in words are sufficient.The force and acceleration graphs both have the same shape. They increase and decrease with the same slope.
