1. In your own words, describe the situation to be studied.
2. List and define all of the parameters to be measured directly.
3. In this experiment you will need to design your own data tables. Use thelist of parameters in #2 above to create appropriate data tables for thisexperiment. Be sure to label each table appropriately.
4. List any quantities that will be calculated.
5. List any graphs that will be created during the analysis of thisexperiment.
1. In this experiment, you will use the ultra-sonic range sensor to studythe motion of a mass on the end of a spring. The mass will be positioned abovethe ranger and the ranger will then produce a graph of position versus time onthe screen.
2. Each lab group will check out a set of springs. If you over-stretch orotherwise permanently damage any of the springs in your set, 2 points will betaken off of the reports from each person in the group for each spring that wasdamaged. DO NOT OVERSTRETCH THE SPRINGS!!!!!
3. To measure the spring constant of the springs, use Hooke's law:F=-kx. Find the average k for three different pairs ofF and x for each spring. Choose the upper, lower, and median ofthe range of masses you plan to use in step 2 so that you will have the averagek value over the range you will be using in your analysis.
4. Step 5 of the procedure asks you to create graphs of the data found insteps 2, 3, and 4. You will be analyzing the shapes of the graphs to determinethe relationships between each of the three parameters and the period of themotion. Therefore, it will be important to take sufficient numbers of datapoints in each case to see whether the data makes a straight line, parabola, sine wave or some other curve. You will have plenty of time to take all the data you need, so be thorough.
1. Your results should include the spring constants for each of the threesprings as well as a statement of the relationship between the period of themotion and each of the three parameters studied: mass, amplitude, and springconstant.
2. Analize each of the three parameters separately. Discuss not onlywhat the relationship was between the period and the parameter, but alsohow you determined the nature of that relationship. Be specific inexpressing your reasioning and support your conclusions with appropriatereferences to your graphs.
3. Discuss why it was necessary to change only one variable at a time whilekeeping the others constant.
