Experiment: When you click on the link, you will see the simulation of the Hooke's law. There are three tabs: Intro, Systems and Energy. The lab uses a simulation developed by University of Colorado at Colorado Boulder Click to start the simulation A. Click "Intro". Choose a spring constant (k) constant below 500 N/m (different than 200N/m). Click all- Applied force, Spring force, Displacement, Equilibrium position and values. Use the red bar to move away from zero; for example at applied force of 18 N, the displacement is 0.090 m and at that stretch, applied force and spring force are equal. TESTERKA www www. te
Force (N) 6 Displacement (m)
6 Change the spring constant to a value higher than 500N/m. Force (N) Displacement(m)
m Test Predictions On 1. Plot the Force (y-axis) vs displacement (x-axis) on EXCEL or on piece of paper. Label the axes and include the units. Insert the graph (Excel or picture) in the space below: 2. Find the spring constant for the spring in Newton/meters from the slope the graph. 3. What forces will stretch each spring for 0.3 m? B. Click" Energy". Choose k=400N/m, select "Energy Plot", "Applied Force", "Displacement", "Equilibrium Position". Move the slide of displacement from 0 to maximum on both the positive and negative side. 1) What is the maximum potential energy? Was it for the positive or negative displacement? 2) What is the minimum potential energy? 3) What is the value of displacement when the energy is half of the maximum value? 4) What is the value of energy when the displacement is half of the maximum value?

C. Problem: A student measured 15s for the 20 complete oscillations for an object of 200g attached at the free end of a spring. Calculate the period of oscillation (T) and the spring constant (k). Write the equation used and then the numerical values.
