Linda Gao Becky Grossman zg2132 Thursday 1:10-4:00pm Laboratory 1 Introduction: In this experiment, we are observing the motion of an object undergoing constant acceleration and experimentally deriving the coefficient of restitution, e, as well as gravitational acceleration, g. Our results of ē w , the weighted mean of e, is 0.520 and g is 10.3 m/s 2 . Our results for ē w did not match our expectations because while ē w should be between 0 and 1, the coefficient should be around 0.8-0.9. Our experimental value, however, is significantly less. Our g, however, meets expectations, because it should be around 9.8 m/s 2 , and our experimental results coincide. Procedure: Velocity: 1. Load the Velocity Lab software on the PC and turn on the air track. Place the ranger on the track at the 150cm mark. 2. Push the ranger to the left as you press “start” on the Velocity Lab software and record data before and after the ranger hits the bumper. The software should plot the motion smoothly. 3. Perform a linear fit on the data before the collision and record the slope v i and the uncertainty σ vi of the slope obtained. 4. Perform a linear fit on the data after the collision and record the slope v f and the uncertainly σ vf of the slope obtained. 5. Repeat steps 2-4 nine more times until you have ten sets of data. Gravitational Acceleration:
