Part I: Mass – Spring System A. Assemble this set up.
Part I: Mass – Spring System Zero the force sensor when the mass is at rest. C. Displace the mass downwards and release from rest to start the oscillations. Record the motion on the Labquest. Determine the period of the motion from the graph. Record the mass and the period. Repeat for 4 different masses.

Questions and Analysis Plot T2 vs. m Get the slope from the best linear fit. Calculate the spring constant: k = 4p2/slope Spring Color Spring Constant (± 5%) Red 25 N/m Blue 30 N/m Yellow 35 N/m White 40 N/m Green 50 N/m
Part II Starter A mass spring system oscillates with a period T. If the mass is quadrupled, the new period is: 1.41 T 2.00 T 2.41 T 4.00 T Tnew/Toriginal = √(mnew/moriginal) =√4 = 2
Part II: The Pendulum Set up a pendulum with a photogate set to read the period. Start the data collection to read the period. Record the period and the length of the string. Adjust the string to a new length and record the new period and length. D. Repeat for 5 different trials.
Setting Up for Pendulum Timing Hook up the Labquest to the computer and start LoggerPro. 2. Go to Experiment> Set Up Sensors> Show All Interfaces 3. Click on the picture of the Photogate and select “ Pendulum Timing”
