7. Determine if the oscillation period is independent of the amplitude of oscillation. To do this, hang a mass of 0.20 kg from the end of the spring. This will stretch the spring to a new neutral position (marked by the black dashed line). From this (neutral) position, pull the spring down an additional 4.0 cm and release it. (You may find using the red dashed line and the pause button to be helpful, here.) Use the stopwatch to measure the time for 50 complete oscillations. Record this result in Data Table 2. Helpful hint: Click on the blue Pause button, move the spring with hanging mass to the desired location, click the "start" arrow on the stopwatch, then when ready click the "Pause" button. This will start both the stopwatch and the oscillations. 8. Repeat stop 7 for an amplitude of 8.0 cm. Complete the discussion based upon Data Table 2. 9. Hang a mass of 0.05 kg from the end of the spring. With an amplitude of 5.0 cm, measure the time for 50 complete oscillations. Record this time in Data Table 3. Determine the period, T, for one complete oscillation. Record this as Imess in the data table. 10. Use the equation, T = 2x M+ (ms/ 3) k to compute the calculated value of the period. Record this data as Tea. Then, compute and record the % Difference between the measured and calculated values of period. (Since my is not given you can take it as a massless spring). 11. Repeat steps 9 and 10 for the loads specified in the data table.+ Table 3: Mass Time 50 osc.
