Within the limits of your experimental accuracy, do you data points define a straight line for each ball? Was the acceleration constant for each ball? If your graphs were linear, measure the slope of each graph. Using your measured slopes, and the equation shown in the introduction, determine the acceleration due to gravity. Be sure to include the units. Was the accel- eration the same for each ball? Conclusion Describe your laboratory experiment and discuss your results. Consider the following questions: (1) Is the accel- eration due to gravity constant? (2) Is the acceleration due to gravity the same for all objects? Discuss the con- ditions under which you believe your answers to be true. Include a discussion of the errors in your measurement and how they affect your conclusions. How linear was your graph? How might you alter your technique, or the experiment, in order to reduce experimental errors?
