regression line in the data table (include units). 8. Using the graphs, estimate the acceleration of the cart when a force of 1.0 N has acted upon it. Select ‘Interpolate’ from the ‘Analyze’ menu. Move the mouse across the graph and determine the acceleration (x) when the force (y) is nearly 1.0 N. Record the force and acceleration in the data table. 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.
