Part II: Constant Mass Difference ( mair) For this part of the experiment you will keep the difference in ma of the Atwood's machine constant and increase the total mass 1) Use 145 g for m, and 135g for m,. Record the new masses 2) Add mass Sg increments to both sides, keeping a constant di 3) Repeat steps 1-2 for each mass combination and record the re Collect motion data and determine the acceleration (slope of done in part I) for at least five different mass combinations. Find calculated value of acceleration using Eq 4b Compare the experimental value of acceleration ( with calculat Data Table 2 Part II: Constant Mass Difference Trial 1 2 3 m 1 m 2 m diff m TOT
