I'm not sure what is the source of error and why.

Your group's goal is to go to each station and solve the problem using data you collect. Take GOOD measurements and think, think, think. Show all of your work. A Free-Body- Diagram with ALL forces is required for each station! You each will be graded on the quality and completeness of the work as well as the answer. Station #1 - What Goes Up Stays Up The Atwood machine at this station consists of two different masses connected vertically by a string over a pulley. The smaller silver/black mass is 0.500kg. GOAL: determine mass of Santa/Shan Yu. a) With the smaller mass setting on the ground and the string over the pulley, hook the larger mass onto the other string and measure the distance from the floor to the bottom of the larger mass. Record below. Using the stopwatch, time how long it takes the larger mass to fall from this height to the floor. Do three trials and calculate an average to use in your calcs.
