Mass-Spring System Lab 1 http://phet.colorado.edu/new/simulations/sims.php?sim=Masses_and_Springs Go to the link above and select the Masses & Springs activity. You may then select RUN NOW! or RUN OFFLINE. If you select to RUN OFFLINE, you will instructed how to download the activity to your computer. Part 1 5 points Create a plot from the data you acquire to determine the spring constant of Spring 1, the left spring, using Hooke’s Law. You are to use the plot to determine the spring constant. Part 2 5 points Determine the mass of the three unknown masses. Show all calculations. Part 3 10 points Place Spring 3 setting to the softest stiffness setting. Create a plot from the data you acquire to determine the spring constant of Spring 3. Your data is to include 6 different masses and the period of oscillation of each mass. DO NOT REPEAT THE HOOKE’S LAW PROCEDURE found in Part 1. What to turn in: Data Table(s) Plot(s) Calculations Results with an explanation of how the plot(s) were used to determine the result Please clearly label each part.
