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. 12. Repeat Steps 5 – 10.
Newton’s Second Law DATA TABLES INCLUDE UNITS WHERE NECESSARY Trial 1 Mass of cart with sensors Regression line for force vs . acceleration data Force pulling cart Acceleration Force closest to 1.0 N Force closest to –1.0 N Trial 2 Mass of cart with sensors and additional mass Regression line for force vs . acceleration data Force pulling cart Acceleration Force closest to 1.0 N Force closest to –1.0 N 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.
