Name: ___Demauri Simpson_______________________________________ M3.6 Laboratory Report 8 Worksheet PhET Simulation: Hooke’s Law Instructions You should download this page and complete all your work directly on the MS Word worksheet using MSWord, following the M3.6 Laboratory Report 8 Instructions. Submit your completed Word document to the M3.6 Laboratory Report 8 dropbox. See the Schedule and Course Rubrics in the Syllabus Module for due dates and grading information. . The website you need for this is Phet Simulations (University of Colorado)   https://phet.colorado.edu/sims/html/hookes-law/latest/hookes-law_en.html On opening the program, click on INTRO =============================================================== Part 1 - Using one spring of force constant 200N/m Use the program to record data in your table below- you will need to click on ‘values’ to take measurements of displacement (extension) from equilibrium.  Force Applied (N) Extension (m) 1 N 0.005 m 10 N 0.050 m 50 N 0.250 m 60 N 0.300 m 75 N 0.375 m 100 N 0.500 m
1. Describe the pattern in your results. How is the force applied related to the extension? Give examples from the data you have taken The experiment's force application and spring's extension are related. The spring will extend farther in response to increased force. It appears that every Newton of force equals 0.005 meters of extension. For instance, 0.500 m of extension is obtained by multiplying 100 N of force by 0.005._______________________________________________________________________ ____________________________________________________________________________ ____________________________________________________________________________ ____________________________________________________________________________ ____________________________________________________________________________ _______________________________________________________ 2. Sketch the arrangement of the spring as shown on the screen. Show the direction of the applied force on the spring AND the spring force on your diagram. Use colour to tell them apart. Diagram: =============================================================================== Part 2 - Using two springs of force constant 200N/m in parallel (side by side) On the main menu go to SYSTEMS. Vary the applied force and record the extension or displacement from equilibrium. NOTE: Use the same force values you used in Part 1. Force applied n Extension m 1 N 0.003 m 10 N 0.025 m 50 N 0.125 m
