2.Place the spring onto the eye hook3.Tie the string to the end of the spring and use the other end to tie to an anchoringpoint that will not move4.Turn on the iOLab software and use the wheel sensor (position) and the forcesensor to collect the data5.Pull on the iOLab unit back and forth 7-10 times to collect sufficient data withsmooth curvesPHYS 1010 – page 1
Lab Assignment Sheet6.Use the graph on the iOLab software to pull 5-8 data points (displacement andforce) to graph on an excel sheet7.Once the data points are in a table on excel, take the negative value of the springforce and this becomes the applied force value8.Graph the applied force and displacement values9.Next, create a math model, a diagrammatic model, and a verbal model of theresultsDiagram of Apparatus:Precautions and caveats: Do not tie the string to something higher than the iOLab unitso that the spring isn’t at an angleData Table with Units:Displacement (m)Spring Force (N)Applied Force (N)0.1914-2.49252.49250.1506-1.9921.9920.1146-1.50521.50520.0769-1.00471.00470.066-0.8950.895PHYS 1010 – page 2
