6. Determine the best fit equation for the Force vs. Acceleration graph using the curve fit tools. Is it linear or some other function? 7. Print a copy of the Force vs. Acceleration graph in your lab notebook and record the equation of best fit in your lab notebook . Trial 2 8 . Attach the 0.500 kg mass to the cart. 9 . Repeat Steps 5 –
7. Sketch a copy of the graph in your lab notebook and record the equation of best fit in your lab not ebook. Data Table – To be created and entered in your Lab Notebooks Trial I Trial 2 ANALYSIS – ANSWER THE ANALYSIS QUESTIO NS IN YOUR LAB NOTEBOOK USING COMPL ETE SENTENCES. 1. Did your predicted graph match your results? Explain how your predicted graph for Force vs Acceleration did or did not match your results. 2. Are the net force on an object and the acceleration of the object directly propor tional? Explain using lab data
. 3. What are the units of the slope of the force vs. acceleration graph? Simplify the units of the slope t o fundamental units (m, kg, s). (Hint: 1 N = 1 kg m/s 2 ) What does the slope of the graph experimentally provide? What general equation is created by finding the slope of the graph? What Law is ‘written’? 4. How could you modify the lab to further identify the relationships between the three terms? Identify a ny tools, materials or methods which could be used to further refine the experiment and explain how you would apply them to the experiment.
