1. What happens to the acceleration of a system when the mass of the system increases but the net force stays constant? 2. What happens to the acceleration of a system when the net applied force increases but the mass of the system does not change? 3. Refer to the data in CI Data Table 2. Make a one-page graph of unbalanced force versus measured acceleration, and draw the best-fitting straight line. Determine the slope of this line. Show the details of the calculation on the graph, and attach the graph to the lab report. 4. What are the units of the slope of your graph
