Lab10 - Phys 201 -Hookes Law.docx Lab 10 - Hooke’s Law using Computer Simulation (Taken from Phet) In this activity the learning objectives are: ● Measuring extension and force using a program ● Recording and explaining data for springs using Hooke’s law ● Recording and explaining data for springs connected in ‘parallel’ arrangements Extra Challenge: ● Describe and explain the relationship between elastic energy stored and extension in a spring. OR set up an investigation of your own The website you need for this is Phet Simulations (University of Colorado) https://phet.colorado.edu/en/simulation/hookes-law On opening the program, click on INTRO EXPT 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. Describe the pattern in your results. How is the force applied related to the extension? Give examples from the data you have taken _________________________________________________________________________ _________________________________________________________________________ _________________________________________________________________________ 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: https://phet.colorado.edu/en/simulation/hookes-law EXPT 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 Experiment 1. Force Applied (N) Extension (m) 4 Explain the main difference in the extension produced by this ‘spring system’ compared to the system in Expt 1. _________________________________________________________________________ _________________________________________________________________________ _________________________________________________________________________ _________________________________________________________________________ _________________________________________________________________________
