10. 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. 11. Repeat Step 10 using a force of –1.0 N. 12. Print copies of each graph (Optional). Trial 2 13. Attach the 0.500-kg mass to the cart. Record the mass of the cart, sensors, and additional mass in the data table. 14. Repeat Steps 7 – 12. Physics with Vernier 9 - 3

Experiment 9 DATA TABLE Trial I Mass of cart with sensors (kg) Regression line for force vs . acceleration data Force pulling cart (N) Acceleration (m/s 2 ) Force closest to 1.0 N Force closest to –1.0 N Trial 2 Mass of cart with sensors and additional mass (kg) Regression line for force vs . acceleration data Force pulling cart (N) Acceleration (m/s 2 ) Force closest to 1.0 N Force closest to –1.0 N ANALYSIS 1.Compare the graphs of force vs.time and acceleration vs.time for a particular trial. 2.Are the net force on an object and the acceleration of the object directly proportional? Explain. 5.What are the units of the slope of the force vs.acceleration graph? Simplify the units of the slope to fundamental units (m, kg, s). 6.For each trial compare the slope of the regression line to the mass being accelerated. What does the slope represent? 7.Write a general equation that relates all three variables: force, mass, and acceleration. 1. Use this apparatus as a way to measure mass. Place an unknown mass on the cart. Measure the acceleration for a known force and determine the mass of the unknown. Compare your answer with the actual mass of the cart, as measured using a balance. 9 - 4 Physics with Vernier
