Procedure sx2g 10g 500g mi m2 500g Figure 2. I. Arrange your system as shown in Figure 2. Place your weights so that you have one 500g mass on each side, and a 10 gram mass on mi and five 2g masses on mz. Measure and record the total distance that mi will travel as it falls from its raised position to the floor. 2. Record the total mass of mi and m2. Be sure to include the mass of the hangers. 3. With mi fully raised, give mi a gentle push. If m and m are of equal mass, then mi should stop falling after a short distance due to the friction in the pulley. Add a lg mass to mi and again give it a gentle push from its raised position. Repeat this process until mi travels to the ground Typically, one or two grams will be sufficient. The amount of mass added to mi is the friction equivalent. Record this value as m without accelerating downward or stopping. and the total mass is: (mi + m2 + m) 61
